ICEQC-R-2011-06 — Teacher Loss, Absence and Deployment in Crisis-Affected Regions

retirement, incapacity, implication, scheduled change the practical judgement in the three conditions under examination because the responsible body must identify distribution, timing and remedy. **Loss** is a reduction in the teachers available to the education authority or to a defined school population: death, injury, abduction, flight, retirement, resignation, dismissal, transfer out or prolonged incapacity can all produce loss, yet each has a different evidentiary basis and policy implication. **Absence** concerns a teacher who remains attached to a post or school but is not available during a scheduled period. **Deployment** concerns the placement and reassignment of teachers across schools, temporary learning spaces, levels, subjects and population groups. A displaced teacher may be lost to the school of origin but available in a receiving locality; a teacher transferred for security may be present in the system while the original community loses its service.

exposure, loss, uses, substitute are material to the three conditions under examination only when the record connects the stated measure to actual delivery and affected learners. The 2011 Education for All Global Monitoring Report placed 28 million primary-school-age children out of school in conflict-affected poor countries and described targeted attacks, forced displacement, sexual violence and chronic insecurity as barriers to education. Its evidence establishes the scale of exposure; it does not supply a uniform teacher-loss rate for every conflict. This study therefore uses conflict status as a reason for differentiated measurement, not as a substitute for a measured numerator.[REF-19]

place, legality, finding, access require the the three conditions under examination analysis to distinguish authority, observed condition and educational effect. A teacher not observed in a school may be on authorised leave, escorting pupils, attending an official meeting, unable to cross a security barrier, working in a temporary site, displaced, detained or unaccounted for. Unannounced observation can establish non-presence at a particular time and place. It cannot by itself assign motive, legality or responsibility. In a crisis-affected locality, any finding of absence requires a dated account of school opening, physical access, official duty, leave status, replacement and the teacher's last confirmed contact.

allocation, administration, date, teacher change the practical judgement in the three conditions under examination because the responsible body must identify distribution, timing and remedy. In stable administration, a current school code and assignment date may suffice. During displacement, the authority may have to link a teacher to an origin school, a present duty station, one or more temporary sites and a population served. Receiving schools may experience sudden enrolment growth while their establishments remain based on an earlier census. Origin schools may remain on the register although pupils and staff have dispersed. A single location field cannot represent these conditions without destroying the distinction between lawful reassignment and unresolved disappearance.

will, absence, formally, wide define the evidentiary boundary in observation population, area and period; aggregate completion cannot substitute for a reasoned account of unequal consequence. The relevant population may be all teachers employed by a ministry, teachers expected at schools that were officially open, teachers assigned to a conflict-affected district, or teachers serving displaced and host-community learners. These populations will yield different results. The denominator for an absence rate cannot include teachers whose schools were formally closed unless the measure explicitly concerns system-wide availability. The denominator for teacher loss must identify whether transfers within the system are exits or changes of location. The denominator for deployment must identify the pupils, classes or curriculum periods against which distribution is judged.

dated, every, district, inaccessible are material to observation population, area and period only when the record connects the stated measure to actual delivery and affected learners. Armed conflict rarely affects every part of a country equally or continuously. A district may contain secure, intermittently accessible and inaccessible schools. A national label conceals this variation, while a permanent school classification may fail to record rapid change. The minimum record attaches a security-access status to the school and reference period, identifies the authority making the classification, and preserves later revisions. It does not ask school personnel to make military judgements; it records the administrative fact relevant to whether a school census, payroll visit or classroom observation could be completed.

annual, return, more, entrants define the evidentiary boundary in observation population, area and period; aggregate completion cannot substitute for a reasoned account of unequal consequence. Point-in-time teacher presence can show an immediate service gap but is vulnerable to day-specific events. Monthly payroll status can conceal days without instruction. Annual headcount may miss repeated displacement and return. The appropriate publication therefore presents more than one temporal view: current stock; entrants and exits during a stated interval; days or periods expected; days or periods observed; and the duration of unresolved vacancies or absence. Where administrative interruption creates an incomplete series, the gap is disclosed rather than bridged by an assumed continuation.

needed, voluntary, incapacity, family define the evidentiary boundary in a cause-specific loss register; aggregate completion cannot substitute for a reasoned account of unequal consequence. Death and permanent incapacity reduce the available workforce and may create family entitlements. Abduction, detention and disappearance require a protected status pending verified information. Flight across a district or national boundary may remove service from one population while preserving the teacher's capacity to serve another. Resignation may reflect insecurity, interrupted pay, family separation, housing loss or an ordinary career decision. Transfer out may be a protective measure rather than attrition. Each category requires an event date, source, confirmation status and subsequent amendment history.

make, every, loss, staffing are material to a cause-specific loss register only when the record connects the stated measure to actual delivery and affected learners. Inaccessible communications, destroyed records and population movement can make immediate confirmation impossible. Classifying every unconfirmed person as an exit overstates loss; retaining every person indefinitely as active overstates available staffing. The defensible response is a separate unconfirmed status accompanied by the date of last verified service, the attempts permitted to establish contact, and the treatment of the post for temporary staffing purposes. Public aggregates may show the count and age of unresolved cases without disclosing names or circumstances that could expose individuals.

after, simultaneously, connect, function change the practical judgement in a cause-specific loss register because the responsible body must identify distribution, timing and remedy. A teacher who resumes duty after displacement, injury or interruption should not appear simultaneously as a new entrant and as a continuing employee. Return records connect the prior status, any changed school or function, the date of resumption and the workload actually accepted. Reconciliation across the opening stock, confirmed losses, temporary interruptions, returns and closing stock prevents the crisis from appearing to create implausible recruitment or disappearance merely because the register was rebuilt.

duties, records, these, insecurity change the practical judgement in absence where access is unstable because the responsible body must identify distribution, timing and remedy. An observer who cannot reach a site has not observed every teacher absent. A school closed by competent authority has no scheduled classroom presence for that interval, though teachers may have other assigned duties. A school operating irregularly requires a calendar that records the periods actually announced to the community. These distinctions preserve the denominator and prevent insecurity from being converted into a judgement about individual conduct.

type, easier, bias, completed change the practical judgement in absence where access is unstable because the responsible body must identify distribution, timing and remedy. Sampling must account for remoteness, school size, level, management type and security-access status. Substitution of an easier school for an inaccessible sampled school introduces selection bias precisely where interruption may be greatest. If a visit cannot be completed, the result remains a non-observation and the coverage rate is published. Telephone or administrative confirmation may provide supplementary evidence, but it is not silently treated as equivalent to direct observation.

unexplained, establish, later, published change the practical judgement in absence where access is unstable because the responsible body must identify distribution, timing and remedy. The categories must remain sufficiently broad for public reporting and sufficiently exact for administrative response. An unexplained status means that available records did not establish a reason by the reporting date. It is not a finding of misconduct. A later verified reason must amend the register and, where material, the published series.

absent, lesson, period, attention define the evidentiary boundary in absence where access is unstable; aggregate completion cannot substitute for a reasoned account of unequal consequence. An absent teacher may create no immediate lost lesson if a prepared replacement delivers the scheduled subject and period; conversely, nominal coverage may divide attention across classes and reduce delivered time. The availability account should therefore show teacher-periods expected, teacher-periods unavailable, periods covered by an appropriately assigned substitute, periods combined or shortened, and periods not delivered. This moves the analysis from personal attendance to educational service without obscuring the employment status of the teacher concerned.

population, role, based, describe require the deployment under displacement analysis to distinguish authority, observed condition and educational effect. UNHCR reported 43. 7 million people displaced worldwide at the end of 2010, including 15. 4 million refugees and 27. 5 million conflict-related internally displaced persons; the publication explicitly excluded displacement arising during 2011. These are population-of-concern statistics, not school-enrolment counts. Their role in workforce planning is to show why origin-based administrative records cannot be assumed to describe the current population requiring teachers.[REF-20]

level, personal, displaced, personnel define the evidentiary boundary in deployment under displacement; aggregate completion cannot substitute for a reasoned account of unequal consequence. It then records existing teachers, displaced teachers who are willing and eligible to serve, temporary personnel, available teaching spaces, curriculum requirements and feasible hours. A crude pupils-per-teacher ratio can identify pressure, but it will not reveal a missing language, subject, female teacher, disability-support capability or secondary-level specialism. Those constraints require separate deployment fields.

preserving, whether, order, itself are material to deployment under displacement only when the record connects the stated measure to actual delivery and affected learners. Some communities remain, some return, and some schools reopen before official population projections are restored. Moving every funded post to a receiving centre may deepen exclusion in the place of origin; freezing every post at its former location may leave teachers and pupils without recognised service elsewhere. A dated dual record permits temporary reassignment while preserving the establishment decision for later review. The authority should state whether salary follows the person, the post or the temporary duty order, since delayed or interrupted payment is itself a retention risk.

distinctions, established, prior, organisation require the deployment under displacement analysis to distinguish authority, observed condition and educational effect. Emergency resources restricted to a displaced population can leave a receiving school with parallel personnel conditions, unequal pupil access or unsupported additional workload. The comparison should therefore report service for displaced and host-community learners under the same definitions, while retaining the legal and funding distinctions required by the responsible authorities. Equity is not established by equal numbers alone; language, prior learning, protection, school distance and class organisation shape the staffing requirement.

hospitals, across, other, personnel are material to attacks, safety and professional status only when the record connects the stated measure to actual delivery and affected learners. These grave violations affect education personnel and pupil access, but incident data and teacher workforce data serve different purposes. An incident count must not be converted into a teacher attrition rate without a defined population and verified linkage.[REF-21]

operating, learners, collecting, mandate are material to attacks, safety and professional status only when the record connects the stated measure to actual delivery and affected learners. It should avoid collecting operational details beyond its educational and protection mandate. Public reporting should aggregate where disclosure could identify a person, route or vulnerable site. The absence of a verified incident in an inaccessible area does not establish safety; it may indicate weak reporting coverage.

placement, reasonable, treating, influence define the evidentiary boundary in attacks, safety and professional status; aggregate completion cannot substitute for a reasoned account of unequal consequence. Housing, transport, communication, school location, accompaniment rules and predictable payment can determine whether a post can be held. Women teachers may face distinct travel, harassment and family constraints, while their absence can reduce participation for girls in settings where families seek female staff. Disability and health conditions can likewise make a formally available placement unusable. Deployment review must therefore examine reasonable support and differentiated risk without treating teachers as interchangeable units.

international, applicable, professional, need require the attacks, safety and professional status analysis to distinguish authority, observed condition and educational effect. Crisis does not remove the need for fair procedures. Protective transfer, temporary reassignment and accelerated recruitment should have a legal basis, a stated duration, review arrangements and an avenue for correction. Emergency need may require flexibility, but ambiguity about status, pay and duty location can itself drive departure and weaken later reconciliation.[REF-02]

origin, movement, east, 2011 define the evidentiary boundary in recent disruption in the middle east and north africa; aggregate completion cannot substitute for a reasoned account of unequal consequence. The available international statistics did not yet provide a complete annual account of the resulting teacher workforce. This report therefore does not present a regional loss total or claim that one pattern applies across the region. It identifies the minimum observations needed while administrative conditions are changing: schools open and accessible; pupils attending by current location; teachers last confirmed and currently serving; temporary learning sites; interrupted payroll; subject and language gaps; and movements between origin and receiving areas.

events, timely, source, limitation are material to recent disruption in the middle east and north africa only when the record connects the stated measure to actual delivery and affected learners. UNHCR's Global Trends 2010 described the position at the end of 2010 and expressly did not cover displacement during 2011, including from Libya and Syria. It remains useful as the latest globally reconciled stock available before the cut-off, but it cannot quantify later events. Current operational counts may be more timely and less complete. They should be dated, labelled by source and kept separate from the annual global stock.[REF-20]

directly, receiving, combine, reception change the practical judgement in recent disruption in the middle east and north africa because the responsible body must identify distribution, timing and remedy. A regional mean can combine origin-area school closure, reception pressure and broadly stable systems. The same numerical change in teachers per pupil can mean teacher flight, pupil flight, newly enrolled displaced children, incomplete school reporting or ordinary demographic change. Interpretation must use the component counts and coverage notes.

general, emergency, ensure, humanitarian define the evidentiary boundary in humanitarian assistance, public authority and continuity; aggregate completion cannot substitute for a reasoned account of unequal consequence. The resolution provides a public-law and policy basis for treating education as part of emergency response; it does not prescribe a common staffing formula. Education authorities remain responsible for defining recognised service, safeguarding professional status and connecting temporary provision to the national system.[REF-22]

arrangement, state, qualification, transition require the humanitarian assistance, public authority and continuity analysis to distinguish authority, observed condition and educational effect. For teacher planning, its relevance is institutional: humanitarian finance is time-bound and directed to urgent needs, while recurrent salaries, establishments and long-term deployment ordinarily require a durable public arrangement. A temporary teaching post should therefore state the employer or contracting body, pay source, qualification rule, supervision, duration and intended transition.[REF-23]

different, preserve, site, unlike are material to humanitarian assistance, public authority and continuity only when the record connects the stated measure to actual delivery and affected learners. A government aggregate may omit teachers financed outside the main payroll; a humanitarian count may include facilitators who do not meet the national definition of teacher; separate agencies may count the same person at different sites. A common minimum record can preserve each organisation's mandate while reconciling person, site, function, workload and period. The aim is not to force unlike personnel into one legal category. It is to establish what instructional service exists and which authority is responsible for its continuation.

risks, rehabilitation, training, remuneration define the evidentiary boundary in humanitarian assistance, public authority and continuity; aggregate completion cannot substitute for a reasoned account of unequal consequence. An education response that expands enrolment without identifying the cost of the next school term risks reopening a service gap. Scenario records should separate one-off rehabilitation, temporary learning-space costs, training, teaching materials, transport and recurrent remuneration. They should identify which expenditure can be absorbed into the public budget, which requires continuing external support, and what reduction in hours, classes or coverage would follow if funds cease.

median, administrative, population, results are material to comparative indicator set only when the record connects the stated measure to actual delivery and affected learners. Each requires an opening or eligible population, an observation interval and rules for transfers. Results should be disaggregated by sex, age or career stage where numbers and protection permit, by school level, location and security-access status, and by origin and current location for displaced teachers.

closure, publishes, weighting, absence define the evidentiary boundary in comparative indicator set; aggregate completion cannot substitute for a reasoned account of unequal consequence. School closure is reported beside, not within, teacher absence. A sample estimate publishes its sampling frame, achieved observations, weighting, uncertainty and substitution rule.

distributional, register, other, deployment are material to comparative indicator set only when the record connects the stated measure to actual delivery and affected learners. National totals are accompanied by ranges or distributional groups. An assignment recorded in the personnel register is not counted as service at the destination until reporting or other valid confirmation occurs.

cannot, recorded, because, denominator require the comparative indicator set analysis to distinguish authority, observed condition and educational effect. Loss, absence, closure, access, deployment and instructional delivery cannot be exchanged through fixed weights. A low recorded absence rate may coexist with extensive school closure because only open, observable schools enter the denominator. A stable national teacher stock may coexist with severe local loss after displacement. A dashboard should preserve those tensions and direct verification, not compress them into a favourable average.

unresolved, temporary, call, arrangements are material to interpretation and decision rules only when the record connects the stated measure to actual delivery and affected learners. A sharp rise in unresolved status calls for safe verification and temporary staffing. Persistent authorised absence may call for replacement capacity or revised duty arrangements. High unexplained absence requires record reconciliation before any employment conclusion. A wide deployment gap calls for examination of establishment rules, incentives, security and teacher preferences. A high closure rate requires a continuity decision that attendance enforcement alone cannot solve.

exists, short, treated, derived require the interpretation and decision rules analysis to distinguish authority, observed condition and educational effect. A school below the minimum number of teachers required to operate its grades or subjects may require immediate action even if the national ratio is favourable. A moderate measured absence rate may require urgent attention where no replacement exists and one teacher serves the whole school. Conversely, a short, authorised interruption with full instructional replacement should not be treated as equivalent to prolonged unserved absence.

genuine, more, access, status define the evidentiary boundary in interpretation and decision rules; aggregate completion cannot substitute for a reasoned account of unequal consequence. A falling pupil–teacher ratio may reflect additional teachers, falling enrolment, pupil displacement or incomplete pupil reporting. A higher attrition rate may reflect genuine departure or improved event recording. More recorded incidents may reflect greater exposure or improved access to reports. Triangulation with enrolment, payroll, school status, population movement and incident coverage is therefore part of the indicator, not an optional narrative addition.

This study uses evidence available by 22 October 2011. It draws on established teacher workforce definitions, the 2011 global review of armed conflict and education, end-2010 displacement statistics released in June 2011, the Secretary-General's April 2011 report on children and armed conflict, the General Assembly's 2010 resolution on education in emergencies and the European Commission's June 2011 humanitarian report.[REF-19] [REF-20] [REF-21] [REF-22] [REF-23]

departures, regions, abstract, measures define the evidentiary boundary in evidence boundaries at 22 october 2011; aggregate completion cannot substitute for a reasoned account of unequal consequence. The principal finding is consequently methodological but not abstract: authorities need separate, reconcilable measures before a global or regional comparison can carry the claimed meaning. The absence of a complete series is itself a constraint on allocation and accountability. It must be reported as missing evidence, not filled with estimates borrowed from a different population.

implement, among, workload, demand require the evidence boundaries at 22 october 2011 analysis to distinguish authority, observed condition and educational effect. They retain distinctions among posts, persons, assignments, presence, workload and delivered instruction; specify supply and demand; examine distribution, finance and professional safeguards; and provide calculation and review records. In crisis-affected use, every such record must also carry current school-operating status, access coverage and origin-to-current-location links where displacement is material.

classes, received, question, incomplete are material to the planning object only when the record connects the stated measure to actual delivery and affected learners. That formulation is incomplete. The object is the sustained provision of instruction by people with the knowledge, preparation and assignment required for the pupils and curriculum concerned. The relevant unit changes as the question changes: persons for recruitment and professional development; full-time equivalents for labour input; posts for establishment control; classes and periods for timetabling; and pupil-hours for service received.

matched, resources, funds, reports are material to the planning object only when the record connects the stated measure to actual delivery and affected learners. It cannot establish whether the growth occurred at the level experiencing enrolment pressure, whether new teachers reached schools, whether they remained, or whether their qualifications matched the assignment. A complete account therefore follows resources through a sequence: post authorised; funds provided; person appointed; person assigned; person reports; person is present; class is scheduled; instruction is delivered. Loss at any transition has a different cause and remedy.

professional, time, compensate, remains are material to the planning object only when the record connects the stated measure to actual delivery and affected learners. The chain does not imply that teaching is reducible to an administrative transaction. It ensures that administrative claims about service can be tested. Professional judgement and classroom relationships operate within the time and conditions made available; they cannot compensate indefinitely for a post that does not exist, a vacancy that remains unfilled or a timetable that provides no teacher for a required subject.

individual, time, relative, current define the evidentiary boundary in eight workforce quantities that must not be merged; aggregate completion cannot substitute for a reasoned account of unequal consequence. A **funded post** is an authorised position for which expenditure is provided for the period. A **filled post** has an appointment recorded. A **person employed** is a unique individual with an active employment relationship. A **full-time equivalent** expresses contracted workload relative to a defined full-time workload. A **school-assigned teacher** has a current duty location in a school. A **teacher present** is observed or validly recorded at the assigned place and time. A **teacher teaching** is delivering a scheduled instructional activity.

administration, payroll, departure, work require the eight workforce quantities that must not be merged analysis to distinguish authority, observed condition and educational effect. One person can fill more than one part-time post; one post can be temporarily covered by several people; a teacher can be seconded to administration while retaining a school code; a payroll record can remain active after departure; and a teacher can be present while engaged in official non-teaching work.

funded, vacancy, assignment, teaching change the practical judgement in the service-conversion account because the responsible body must identify distribution, timing and remedy. The funded-post gap is authorised posts minus funded posts. The vacancy gap is funded posts minus filled full-time equivalents. The assignment gap is employed teacher full-time equivalents minus school-assigned teaching full-time equivalents, after legitimate central, leave and support functions are separately classified. The availability gap is scheduled teacher time minus teacher time available after recorded absence. The delivery gap is available time minus instruction delivered.

authorised, employment, remove, school change the practical judgement in the service-conversion account because the responsible body must identify distribution, timing and remedy. A gap can be legitimate: authorised positions may be phased in; leave is a lawful employment condition; professional development may temporarily remove a teacher from class; emergencies may close a school. The account requires reasons and replacement arrangements. Its purpose is to distinguish explained service variation from unresolved loss and to show which authority can act.

because, careless, subtracted, work are material to the service-conversion account only when the record connects the stated measure to actual delivery and affected learners. Posts cannot be subtracted directly from headcount where part-time work is material. Presence observed on one day cannot be subtracted from an annual full-time-equivalent stock. The comparison must first align unit and reference period. Where alignment is impossible, the quantities are reported side by side with the incompatibility stated.

difficult, workforce, function, curriculum define the evidentiary boundary in public-interest basis; aggregate completion cannot substitute for a reasoned account of unequal consequence. Workforce administration is therefore not only an internal management function. Allocation decisions determine whether curriculum, language provision, reasonable school access and continuity of instruction exist in practice.[REF-01] [REF-12]

staffing, inequitable, remote, serving change the practical judgement in public-interest basis because the responsible body must identify distribution, timing and remedy. Equal ratios can be inequitable where need and cost differ. A small remote school may require a minimum complement even when its ratio is low; a school serving multiple languages or children requiring specialised support may require additional capability. The public-interest obligation is to apply explicit, relevant criteria and to make the resulting distribution visible.

final, need, consultation, remote change the practical judgement in public-interest basis because the responsible body must identify distribution, timing and remedy. These matters are linked. Deployment cannot be sustained by transfer orders alone when housing, safety, professional support, family circumstances and career progression make a post materially more difficult to hold. A measurement system that reports the vacancy but not the repeated turnover or the conditions of service identifies only the final symptom.[REF-02]

dated, qualification, establishment, subject define the evidentiary boundary in person, post and assignment; aggregate completion cannot substitute for a reasoned account of unequal consequence. The post is the appropriate unit for establishment authority and vacancy. The assignment is the appropriate unit for school, level, subject, grade and function. A controlled register preserves all three and links them with dated identifiers.

serve, include, training, posts are material to person, post and assignment only when the record connects the stated measure to actual delivery and affected learners. Counting persons without assignments can include teachers working in administrative offices, teacher-training institutions or non-school functions. Counting filled posts can double count an individual holding fractions of more than one post. The statistical publication is to state which unit is used and how concurrent assignments are consolidated.

revision, requires, snapshot, distinguish require the person, post and assignment analysis to distinguish authority, observed condition and educational effect. An annual snapshot without transaction dates cannot distinguish a genuine movement from late data entry. Retrospective corrections must remain auditable: the corrected value may replace an erroneous public series, but the reason, scale and release date of the revision are to be retained.

headcount, retirement, full, labour require the headcount and full-time equivalent analysis to distinguish authority, observed condition and educational effect. It is essential for recruitment, retirement, professional development and occupational conditions. Full-time equivalent measures purchased or assigned labour relative to the national full-time rule. It is more suitable for resource ratios where part-time employment is material. Neither is inherently superior; they answer different questions.

recorded, hours, contracted, teaching are material to headcount and full-time equivalent only when the record connects the stated measure to actual delivery and affected learners. 9. If the hours include duties beyond teaching, this is not 1. 9 instructional full-time equivalents. A further conversion using scheduled contact time is required. Definitions of full-time work, contact time and paid non-contact duty must be recorded.

participation, 2004, students, comparison are material to headcount and full-time equivalent only when the record connects the stated measure to actual delivery and affected learners. Some systems may classify a person by status; others may divide actual or contractual hours. A ratio calculated from full-time-equivalent pupils and teachers is not comparable with one using headcounts unless part-time participation is negligible or an adjustment is made. *Education at a Glance 2004* expressly bases the student–teacher ratio on full-time-equivalent students and teachers and distinguishes it from class size.[REF-08]

occupational, instruction, work, whether are material to teaching and non-teaching functions only when the record connects the stated measure to actual delivery and affected learners. Systems differ in whether school leaders retain teaching loads and whether specialist support staff are classified as teachers. The function performed in the reference period is therefore required in addition to occupational title.

ratio, direct, definition, another require the teaching and non-teaching functions analysis to distinguish authority, observed condition and educational effect. Personnel wholly assigned to administration or another level are not to be included merely because their payroll grade is “teacher”. Where a principal teaches part of the timetable, only the corresponding instructional workload enters an instructional-capacity measure, while the person remains in the headcount for workforce analysis.

proportion, management, teachers, classification change the practical judgement in teaching and non-teaching functions because the responsible body must identify distribution, timing and remedy. The OECD evidence shows wide differences in the proportion and composition of non-teaching staff, reflecting organisation and management. Administrative and support functions can protect teachers' instructional time. The analytical requirement is accurate classification, not automatic transfer of every paid hour into classroom teaching.[REF-08]

categories, different, permanent, community are material to employment status and contingent capacity only when the record connects the stated measure to actual delivery and affected learners. Employment status affects cost, security, turnover, eligibility for training and the reliability of future supply. The categories are to be reported separately where they carry materially different rights, qualification rules or workloads.

persist, explicit, status, support require the employment status and contingent capacity analysis to distinguish authority, observed condition and educational effect. Volunteers may extend access in an emergency or remote setting, yet their service cannot be assumed to persist in a multi-year projection without an explicit retention and remuneration basis. Contract status is not a proxy for quality; the relevant evidence concerns preparation, selection, support, workload, conditions and observed teaching.

political, such, salary, selection require the employment status and contingent capacity analysis to distinguish authority, observed condition and educational effect. A planning model may test such arrangements but cannot treat lower salary as an efficiency gain without accounting for selection, training, turnover, supervision and the continuity of service.[REF-07]

three, qualification, recognised, international change the practical judgement in qualification and training status because the responsible body must identify distribution, timing and remedy. **Academic qualification** concerns general or subject education. **Professional qualification** concerns completion of the recognised preparation for teaching. **Trained status** in international reporting commonly means that the teacher has received the minimum organised teacher training required in the country. The third category is nationally defined and cannot establish an internationally uniform preparation threshold.[REF-04] [REF-05]

holder, rules, licensed, statuses define the evidentiary boundary in qualification and training status; aggregate completion cannot substitute for a reasoned account of unequal consequence. A simple yes/no field discards information needed when rules change. Teachers in training, provisionally licensed or admitted through an alternative route are to have distinct statuses rather than being forced into “trained” or “untrained”.

proportion, among, does, status are material to qualification and training status only when the record connects the stated measure to actual delivery and affected learners. It must not be added to the trained numerator, nor automatically treated as untrained. A published proportion is to show the denominator and the share unknown. If trained status is 80 per cent among the 75 per cent of teachers with known records, the result does not establish that 80 per cent of the full workforce is trained.

teaching, employed, closing, plus change the practical judgement in the stock-and-flow identity because the responsible body must identify distribution, timing and remedy. The identity is to be applied separately to headcount and full-time equivalents. It also requires a boundary: movement from primary to secondary teaching is an exit from the primary stock even if the person remains employed by the same ministry.

difference, investigated, identity, closing are material to the stock-and-flow identity only when the record connects the stated measure to actual delivery and affected learners. If the recorded closing stock cannot be derived from opening stock and transactions, either events are missing, records are duplicated, or definitions changed. The difference is a reconciliation residual, not net recruitment. It is to be reported and investigated before the series is used for projection.

stock, systems, loads, growth define the evidentiary boundary in the stock-and-flow identity; aggregate completion cannot substitute for a reasoned account of unequal consequence. A stock of 100,000 can remain constant after 10,000 entries and 10,000 exits, or after 1,000 entries and 1,000 exits. These systems have different training requirements, induction loads, experience profiles and continuity risks. A net-growth figure conceals them.

eligible, preparation, application, duty change the practical judgement in entry pathway because the responsible body must identify distribution, timing and remedy. Attrition occurs at every transition. Training capacity is therefore not the same as employable supply.

resolve, staff, communities, admitted define the evidentiary boundary in entry pathway; aggregate completion cannot substitute for a reasoned account of unequal consequence. Field of study, language, level and intended location matter. A surplus of general primary candidates does not resolve a shortage of mathematics teachers, bilingual teachers or staff willing and able to serve isolated communities.

already, exists, additional, capacity change the practical judgement in entry pathway because the responsible body must identify distribution, timing and remedy. Expansion planned for the following school year cannot be met through a preparation programme lasting several years unless candidates are already in the pathway or a lawful interim route exists. A projection is to show the earliest date at which additional prepared entrants can reach schools and the capacity required in training institutions, practicum placements and induction support.

period, stock, death, renewal define the evidentiary boundary in exit, attrition and mobility; aggregate completion cannot substitute for a reasoned account of unequal consequence. The denominator is ordinarily the relevant workforce at the beginning of the period, but average-stock denominators may be used if stated. Retirement, death, resignation, dismissal and expiry without renewal are different causes. Transfers between schools are turnover for the school but not attrition from the national workforce. Transfers between levels or occupations depend on the defined boundary.

long, aids, teacher, additional define the evidentiary boundary in exit, attrition and mobility; aggregate completion cannot substitute for a reasoned account of unequal consequence. Retirement projections require age and, where relevant, service eligibility. Mortality and long illness may be material in countries affected by HIV/AIDS; the 2003 costing study treated teacher sickness, absence, death, replacement and additional training as connected planning costs rather than as a single attrition rate.[REF-07]

leaving, codes, renewal, central define the evidentiary boundary in exit, attrition and mobility; aggregate completion cannot substitute for a reasoned account of unequal consequence. “Resignation” may conceal non-renewal, migration to another education employer or movement to a central post. “Unknown” must remain visible. Exit interviews can add explanation but are subject to non-response and may not represent those leaving under the most difficult conditions.

schools, recruitment, gross, transfers require the replacement demand and growth demand analysis to distinguish authority, observed condition and educational effect. Replacement demand is the recruitment required to offset exits and reductions in workload. Gross recruitment need is their sum, adjusted for expected re-entry and transfers in. A system with stable enrolment may still face a large requirement where the workforce is ageing or attrition is high.

training, qualified, institutional, entrants require the replacement demand and growth demand analysis to distinguish authority, observed condition and educational effect. New entrants themselves can leave before the horizon; recruitment in one year changes the age and experience distribution in later years. Training institutions also require teachers and may draw from the same qualified population. The model must state whether this institutional demand is included.

present, view, rules, about require the age and experience structure analysis to distinguish authority, observed condition and educational effect. Experience distribution provides information about induction and career structure but must distinguish total teaching experience from tenure in the present school.

successful, leadership, depends, highly define the evidentiary boundary in age and experience structure; aggregate completion cannot substitute for a reasoned account of unequal consequence. A very young workforce may indicate successful expansion and a heavy requirement for induction, mentoring and leadership development. The planning interpretation therefore depends on the shape of the distribution, not an average age alone.

personnel, protection, small, dates change the practical judgement in age and experience structure because the responsible body must identify distribution, timing and remedy. Public tables use grouped ages and suppress small cells where identification is possible. Missing dates of birth are not to be assigned to the modal age; they are reported as unknown and investigated through personnel controls.

enrolment, training, affect, estimate require the scenario uncertainty analysis to distinguish authority, observed condition and educational effect. Enrolment, repetition, progression, retirement, attrition, training yield, workload and salary assumptions all affect the result. The reportable output is not only a central estimate but a range under plausible variants and an account of which assumptions drive the range.

enrolment, ratios, stronger, demographic require the scenario uncertainty analysis to distinguish authority, observed condition and educational effect. A lower case may reflect slower demographic growth, improved deployment and reduced repetition. These are not optimistic and pessimistic labels unless the educational consequences are established. A lower teacher count produced by exclusion or curtailed curriculum is not a favourable outcome.

district, settlement, entry, transfer change the practical judgement in pupil projections are the starting point, not the staffing because the responsible body must identify distribution, timing and remedy. Each component carries uncertainty. A national-age population does not reveal where pupils will attend; district and school demand also depends on migration, settlement and school choice.

assumes, divisible, grades, pupil change the practical judgement in pupil projections are the starting point, not the staffing because the responsible body must identify distribution, timing and remedy. Collapsing all primary enrolment into one total assumes that teachers and classroom places are perfectly divisible and transferable. A school with 83 pupils across six grades does not create the same staffing requirement as 83 pupils in one grade at a large urban school.

insufficient, expansion, reform, permit change the practical judgement in pupil projections are the starting point, not the staffing because the responsible body must identify distribution, timing and remedy. The model must permit policy shocks and show their implementation date. A straight-line trend is insufficient where the underlying rules change.

planning, rules, require, loses define the evidentiary boundary in class formation; aggregate completion cannot substitute for a reasoned account of unequal consequence. Rounding matters: 41 pupils under a planning maximum of 40 require two classes, not 1. 025 teachers. Applying a ratio at national level loses this indivisibility.

deficiency, combined, materials, demand define the evidentiary boundary in class formation; aggregate completion cannot substitute for a reasoned account of unequal consequence. Its staffing requirement depends on the grades combined, curriculum design, teacher preparation, materials and timetable. A model that assumes one teacher per grade can overstate demand in sparse areas; a model that assumes unrestricted combination can understate the professional and instructional requirement.

work, time, separate, differently change the practical judgement in class formation because the responsible body must identify distribution, timing and remedy. If teachers work both shifts, workload and contact-time rules govern feasibility and cost. If separate teachers are employed, classroom capacity and teacher demand move differently. Shift status must therefore be explicit in school records.

teach, contact, individual, pooled require the curriculum periods and subject specialisation analysis to distinguish authority, observed condition and educational effect. The aggregate number of periods can balance while individual schools have fractional shortages that cannot be pooled across distance.

vocational, preparation, effective, lead define the evidentiary boundary in curriculum periods and subject specialisation; aggregate completion cannot substitute for a reasoned account of unequal consequence. Additional science, language, arts or vocational periods may require staff with different preparation. The implementation plan must therefore connect curriculum effective dates to recruitment, retraining and deployment lead times.

disciplines, field, every, equivalence change the practical judgement in curriculum periods and subject specialisation because the responsible body must identify distribution, timing and remedy. “Science” may denote integrated science at one level and separate disciplines at another. A teacher academically prepared in one field cannot be counted as fully deployable to every subject in a broad family without a stated equivalence rule.

meetings, contact, teachers, materially require the teacher contact time analysis to distinguish authority, observed condition and educational effect. Net teaching or contact time is the scheduled time of direct instruction. The number of teachers required for a given curriculum depends materially on contact-time obligations.

differences, class, limit, ratios require the teacher contact time analysis to distinguish authority, observed condition and educational effect. These differences help explain why similar enrolment and class size can require different numbers of teachers. They also limit direct comparison of student–teacher ratios without the timetable context.[REF-08]

reduce, sound, part, lawful require the teacher contact time analysis to distinguish authority, observed condition and educational effect. School closure, absence, examinations, training and timetable interruption can reduce actual time. Nor is maximising contact hours necessarily sound: preparation, assessment and professional collaboration are part of teaching quality. Planning requires a lawful and educationally credible allocation of total working time.

specific, small, inefficient, functions change the practical judgement in minimum viable staffing because the responsible body must identify distribution, timing and remedy. A minimum complement may be required for leadership, safeguarding, subject coverage or continuity during absence. The requirement is context-specific and may create low pupil–teacher ratios in small schools. Such ratios must not be automatically labelled inefficient.

applies, teachers, transport, staff are material to minimum viable staffing only when the record connects the stated measure to actual delivery and affected learners. Transport time and reliability enter the calculation where staff serve more than one site.

located, geographic, minimum, dispersed change the practical judgement in minimum viable staffing because the responsible body must identify distribution, timing and remedy. It is to be distinguished from avoidable fragmentation caused by poorly located schools or uncoordinated provision. The distinction requires geographic and community evidence, not the ratio alone.

actual, entitlement, while, hold change the practical judgement in national balance is not local sufficiency because the responsible body must identify distribution, timing and remedy. The arithmetic balance is therefore a necessary reconciliation result, not a finding of equitable supply. Deployment measures compare actual assignment with a transparent school or district entitlement.

schedule, shifts, actual, requires define the evidentiary boundary in national balance is not local sufficiency; aggregate completion cannot substitute for a reasoned account of unequal consequence. A rule based only on pupils may fail small schools or subject-specialist programmes. A historical post schedule may preserve allocations after enrolment shifts. The measure is strongest when both the allocation rule and actual circumstances are published.

give, median, show, pupil require the distributional statistics analysis to distinguish authority, observed condition and educational effect. The unweighted mean of school ratios answers a different question and can give small schools disproportionate influence. The median school ratio describes the middle school, while percentiles show dispersion. All may be useful if labelled.

standards, alone, very, tenth change the practical judgement in distributional statistics because the responsible body must identify distribution, timing and remedy. Interquartile ranges, tenth and ninetieth percentiles, and shares of pupils in schools beyond defined planning bands provide a more informative distribution. Planning bands are administrative thresholds, not universal quality standards, and the publication is to explain their basis.

isolation, delayed, coarse, post change the practical judgement in rural and remote deployment because the responsible body must identify distribution, timing and remedy. A single hardship label is too coarse. The register is to identify the actual characteristics of the post and the duration for which it remains vacant or repeatedly turns over.

paid, measure, housing, areas are material to rural and remote deployment only when the record connects the stated measure to actual delivery and affected learners. Measurement of incentives therefore includes eligibility, receipt, timeliness and retention after receipt. An allowance announced but not paid cannot be classified as an implemented deployment measure.[REF-02]

sustained, establish, regions, preparation require the rural and remote deployment analysis to distinguish authority, observed condition and educational effect. The evidence is to distinguish admission, completion, appointment and sustained service. A quota at the first stage does not establish a change at the school.

location, employment, legitimate, role change the practical judgement in gender and workforce distribution because the responsible body must identify distribution, timing and remedy. It is not a universal measure of quality. Interpretation requires level, location, leadership distribution, subject assignment and employment status.

needs, subject, constraint, opportunity change the practical judgement in gender and workforce distribution because the responsible body must identify distribution, timing and remedy. Publication therefore needs cross-tabulation by location and level, subject to confidentiality. Policy responses are to address the documented constraint—such as housing, safety, recruitment opportunity or discriminatory practice—rather than infer one from the aggregate.

among, quality, preparation, counts are material to subject, language and grade mismatch only when the record connects the stated measure to actual delivery and affected learners. The mismatch rate counts assigned instructional workload outside a defined acceptable field. A person-based rate is less precise when teachers divide time among matched and unmatched subjects.

capability, record, classification, personal define the evidentiary boundary in subject, language and grade mismatch; aggregate completion cannot substitute for a reasoned account of unequal consequence. The data system is to record demonstrable language capacity using a lawful and relevant classification. Ethnicity must not be used as a proxy for language competence. Personal data require protection and voluntary, appropriate collection where relevant.

early, treatment, teachers, instruction require the subject, language and grade mismatch analysis to distinguish authority, observed condition and educational effect. A system may place less experienced or less prepared teachers in the earliest grades although foundational instruction carries distinct demands. Experience alone does not determine fitness; the required evidence concerns preparation, support and assignment.

period, appointments, rate, point are material to turnover and continuity only when the record connects the stated measure to actual delivery and affected learners. Turnover reveals repeated disruption. School-level turnover is the number of arrivals and departures during a period relative to the average workforce, with expansion appointments identified separately. High turnover can coexist with a low vacancy rate if posts are repeatedly refilled.

curriculum, collaboration, mobility, whether require the turnover and continuity analysis to distinguish authority, observed condition and educational effect. It does not justify preventing lawful mobility or preserving unsuitable assignments. The policy question is whether avoidable conditions cause disproportionate instability and whether replacements arrive before service is interrupted.

unequal, mechanisms, available, published change the practical judgement in deployment decision rules because the responsible body must identify distribution, timing and remedy. A rule based on seniority alone may not resolve subject gaps; a discretionary rule without reasons creates risk of unequal treatment. Teacher participation and appeal mechanisms are consistent with professional status and can improve the evidence available for durable assignment.[REF-02]

decisions, arrival, register, record change the practical judgement in deployment decision rules because the responsible body must identify distribution, timing and remedy. An order is not a completed transfer. The personnel register, payroll cost centre and school record are to be reconciled after movement so that the same teacher is not retained in two locations.

directly, teachers, training, generally require the what the international table can and cannot show analysis to distinguish authority, observed condition and educational effect. The table generally refers to the 2001/02 school year and identifies values as preliminary. It draws on data compiled by the UNESCO Institute for Statistics from official national responses.[REF-05]

collection, teachers, preparation, teacher are material to what the international table can and cannot show only when the record connects the stated measure to actual delivery and affected learners. It defines trained teachers by national minimum requirements and cautions that preparation varies greatly. It defines the primary pupil–teacher ratio as enrolled primary pupils divided by primary teachers, regardless of teaching assignment. It also notes that definitions, grade-specific class size and hours taught affect comparability. Those qualifications are part of the result, not peripheral notes.

these, aggregate, class, table define the evidentiary boundary in reading the regional pattern; aggregate completion cannot substitute for a reasoned account of unequal consequence. The reported ratio is 40 pupils per teacher for low-income economies and 22 for middle-income economies; regional values are 45 in sub-Saharan Africa and 42 in South Asia, compared with 17 in Europe and Central Asia and in high-income economies. These figures signal materially different aggregate staffing conditions. They do not indicate the number of pupils in a class or the amount of contact time each receives.

status, cannot, nevertheless, reporting define the evidentiary boundary in reading the regional pattern; aggregate completion cannot substitute for a reasoned account of unequal consequence. Sub-Saharan Africa is reported at 80. 4 per cent trained and 45 pupils per teacher, South Asia at 66. 9 per cent and 42, and Latin America and the Caribbean at 76. 7 per cent and 26. Because trained status follows national requirements, the percentage cannot be read as a common proficiency scale. It nevertheless reveals the scale of the nationally recognised preparation gap within each reporting boundary.

unsound, require, weighting, offset change the practical judgement in reading the regional pattern because the responsible body must identify distribution, timing and remedy. Combining a trained share and a ratio would require assumptions about equivalence, substitution and weighting. Ten additional pupils per teacher cannot be offset arithmetically by a specified number of percentage points in trained status. They describe different conditions and may call for different interventions.

national, diagnosis, wide, include change the practical judgement in country variation and data completeness because the responsible body must identify distribution, timing and remedy. Examples reported for 2001/02 include primary pupil–teacher ratios of 10 in Denmark and the Netherlands, 14 in Cuba and Estonia, 20 in China and Malaysia, 40 in India and Nepal, 56 in Cambodia, Mali and the Republic of Congo, 61 in Cameroon, 66 in Mozambique and 71 in Chad. These selected values are not a ranking; they demonstrate the range that a national average can occupy and the need for contextual diagnosis.[REF-05]

number, source, interpret, training define the evidentiary boundary in country variation and data completeness; aggregate completion cannot substitute for a reasoned account of unequal consequence. Missingness limits any analysis restricted to complete pairs and may produce a non-representative sample. The proper publication reports the number of countries and population coverage contributing to an aggregate when the source makes that information available; it does not interpret an absent value as zero or full compliance.

country, table, individual, source are material to country variation and data completeness only when the record connects the stated measure to actual delivery and affected learners. A comparative extract is therefore to carry the country-specific note. The convenience of a single table does not remove this obligation.

class, demonstrates, ratios, pupil require the resource ratio versus class size analysis to distinguish authority, observed condition and educational effect. It defines class size through the number of students in a class or teaching group. The report demonstrates that two countries can have similar student–teacher ratios and different class sizes because teacher working time, pupil instruction time and the organisation of groups differ.[REF-08]

lower, operate, favourable, relation change the practical judgement in resource ratio versus class size because the responsible body must identify distribution, timing and remedy. Average class size rises with the number of pupils and pupil instructional periods and falls with the number of teachers and teacher contact periods, subject to scheduling and school constraints. Consequently, a system can reduce a resource ratio by employing more teachers without reducing class size if those teachers have lower contact loads or undertake other functions. It can operate relatively small classes with a less favourable ratio if pupil instruction time or teacher organisation differs.

results, language, staffing, instrument require the resource ratio versus class size analysis to distinguish authority, observed condition and educational effect. A class-size policy affects rooms, class formation and timetables; a staffing-ratio policy affects aggregate labour resources. They interact but are not the same instrument.

publication, institutions, working, administration define the evidentiary boundary in comparative teaching time; aggregate completion cannot substitute for a reasoned account of unequal consequence. Preparation, assessment, professional activity and administration may be regulated differently. The comparison is useful because the same teacher FTE can support different quantities of scheduled instruction under different contact-time rules.[REF-08]

depend, definitions, without, time define the evidentiary boundary in comparative teaching time; aggregate completion cannot substitute for a reasoned account of unequal consequence. Weekly loads cannot be compared without the number of teaching weeks. Statutory time is not observed time. A complete comparative account identifies whether a value is required, scheduled or delivered.

indian, peru, india, listed change the practical judgement in evidence on presence because the responsible body must identify distribution, timing and remedy. For the primary-school observations reproduced in its table 1. 2, the reported rates were 16 per cent in Ecuador, 25 per cent for an average of 14 Indian states, 18 per cent in Indonesia, 15 per cent in Papua New Guinea, 13 per cent in Peru, 17 per cent in Zambia and 26 per cent in Uganda. The related state table for India ranged from 15 per cent in Gujarat to 39 per cent in Bihar among the listed states.[REF-06]

2003, large, subset, pupil require the costing evidence and the status of 40:1 analysis to distinguish authority, observed condition and educational effect. In its adjusted sample, primary pupil–teacher ratios ranged from 13:1 to 79:1. The group characterised by relatively higher primary completion had an average ratio of 39:1; the full sample average was 44:1. The study used 40:1 as a 2015 parameter in simulations that also adjusted salary, repetition, non-teacher inputs, public finance and private enrolment.[REF-07]

benchmark, itself, model, perfectly require the costing evidence and the status of 40:1 analysis to distinguish authority, observed condition and educational effect. It acknowledges that pupil–teacher ratio is not perfectly correlated with class size, that country geography can constrain deployment, and that the parameter forms one part of a balanced package. Its regression table reported essentially no independent association for the ratio within the specified model after other variables were included, while repetition and spending variables carried different relationships. That result does not prove ratio is irrelevant; it warns against presenting the benchmark as an isolated causal threshold.

pupil, completion, teacher, ratios require the costing evidence and the status of 40:1 analysis to distinguish authority, observed condition and educational effect. One group combined high enrolment with low completion and very high repetition. Another combined low coverage, high teacher salaries relative to national income and high ratios. In each case, changing teacher numbers alone would leave a material constraint unresolved.[REF-07]

assessment, resources, remains, teaching are material to a bounded comparative conclusion only when the record connects the stated measure to actual delivery and affected learners. Large differences in aggregate teacher resources exist; nationally recognised preparation remains incomplete in many reporting systems; teaching-time organisation affects the meaning of resource ratios; and presence losses can materially reduce service. The evidence does not support a universal staffing number, a common training-quality scale or a global estimate of delivered instructional FTE.

about, more, reporting, regions require the a bounded comparative conclusion analysis to distinguish authority, observed condition and educational effect. It may identify systems or regions for further investigation, but policy selection follows national and subnational diagnosis. The stronger the claim—especially a claim about quality, causation or individual conduct—the more direct the evidence required.

presence, specified, term, measure require the presence as a service-delivery measure analysis to distinguish authority, observed condition and educational effect. It is narrower than attendance over a term and broader than unauthorised absence. A valid presence measure begins with a roster of persons expected, excludes those not scheduled, and records the reason and authorisation status separately from the initial observation.

sampling, visits, estimates, define change the practical judgement in presence as a service-delivery measure because the responsible body must identify distribution, timing and remedy. Repeated visits across days and seasons are required for system estimates. The 2004 *World Development Report* tables define absence as a person supposed to be present but not present during an unannounced visit, including authorised and unauthorised reasons. The preliminary country estimates ranged from 13 to 26 per cent for the primary-school observations shown, while the reported state values within India ranged more widely. These figures demonstrate measurement relevance; they do not establish a current rate for every school or a cause applicable across countries.[REF-06]

rules, more, retrospective, data define the evidentiary boundary in presence as a service-delivery measure; aggregate completion cannot substitute for a reasoned account of unequal consequence. Observation and administrative data therefore provide complementary checks. Payroll deductions are not a presence measure, since authorised leave, delayed processing and sanctions follow different rules.

unauthorised, verification, because, replacement are material to reasons, duration and replacement only when the record connects the stated measure to actual delivery and affected learners. The classification is completed after verification, not inferred by an observer. Duration matters because one extended absence and repeated single-day absence have different replacement and continuity effects.

scheduled, number, combining, reducing define the evidentiary boundary in reasons, duration and replacement; aggregate completion cannot substitute for a reasoned account of unequal consequence. The educational loss is scheduled periods not delivered or materially curtailed, not the number of absent persons alone. Replacement by combining classes may preserve supervision while reducing instructional conditions; it is reported as a distinct arrangement.

school, intended, insecurity, building are material to calendar, closure and timetable loss only when the record connects the stated measure to actual delivery and affected learners. School-level closure can result from weather, insecurity, elections, examinations, public-health events, building failure or local administrative decisions. Teacher presence cannot restore time when the school is closed, so closure is measured separately.

finish, reduce, sampled, burden require the calendar, closure and timetable loss analysis to distinguish authority, observed condition and educational effect. Reliable measurement may use sampled observation, timetable records and school logs. The burden is to be proportionate: the objective is a defensible system estimate and timely local response, not continuous surveillance of every professional action.

included, assumes, actual, target require the from employed fte to instructional fte analysis to distinguish authority, observed condition and educational effect. The example is not a performance target. It shows why a payroll stock can overstate delivered capacity and why double-counting losses must be avoided. If absence is already included in delivered-period data, it is not applied again.

2005, context, workforce, instructional change the practical judgement in capacity is not quality because the responsible body must identify distribution, timing and remedy. It cannot establish clarity of explanation, appropriateness of pedagogy, classroom climate, formative assessment or learning. The quality framework in the 2005 EFA Global Monitoring Report connects learner characteristics, context, enabling inputs, teaching and learning activities, and outcomes; the workforce account occupies only part of this wider structure.[REF-03]

weights, limitation, score, contact require the capacity is not quality analysis to distinguish authority, observed condition and educational effect. Credentials, experience, presence and contact time are not interchangeable and cannot be added without arbitrary weights. Each measure supports a specific decision and retains its limitation.

subject, start, sensitive, personnel define the evidentiary boundary in personnel register; aggregate completion cannot substitute for a reasoned account of unequal consequence. Its minimum fields include identifier, employment status, workload, preparation, subject or grade field, employing authority, assignment, start and end dates, leave status and source of verification. Sensitive information is protected and public outputs are aggregated.

name, persons, access, function require the personnel register analysis to distinguish authority, observed condition and educational effect. A correction procedure is required for errors, and access to personal records is logged. The statistical function does not require publication of names, salary details or individual attendance.

payroll, school, without, persons require the establishment and payroll analysis to distinguish authority, observed condition and educational effect. They are related but neither proves school service. Reconciliation identifies active payments without a current personnel record, filled posts without payment, persons charged to the wrong location, duplicated payments and delayed removal after exit.

exception, timing, secondment, records require the establishment and payroll analysis to distinguish authority, observed condition and educational effect. Timing differences, lawful arrears and approved secondment can explain a mismatch. The control result records resolution and prevents unresolved exceptions from silently entering published teacher totals.

reconciliation, pupils, reference, nevertheless are material to school census and timetable records only when the record connects the stated measure to actual delivery and affected learners. It is indispensable for deployment ratios. It may nevertheless count staff reported by the head teacher rather than verified persons, omit teachers temporarily away or include visitors. Stable school and person identifiers permit reconciliation.

supported, assignment, subject, assigns change the practical judgement in school census and timetable records because the responsible body must identify distribution, timing and remedy. They require period length, subject, grade or class, teacher and day. A timetable that assigns one person simultaneously to different classes is internally invalid. Rule-based validation may identify the conflict, but its correction remains an administrative task supported by the school record.

enrolment, data, calculated, status change the practical judgement in training-provider pathway because the responsible body must identify distribution, timing and remedy. These data require cohort identifiers so that completion yield is not calculated from unrelated annual totals. Recognition status and programme changes are dated.

assumption, lawful, aggregate, level change the practical judgement in training-provider pathway because the responsible body must identify distribution, timing and remedy. Public analysis reports aggregate transitions and does not expose applicant-level results. Where linkage is unavailable, the uncertainty between completions and appointments is stated rather than filled by assumption.

exit, international, preserved, level are material to master classifications only when the record connects the stated measure to actual delivery and affected learners. ISCED 1997 supports international level mapping, while national detail is preserved beneath that map.[REF-10]

creates, recoded, therefore, trained are material to master classifications only when the record connects the stated measure to actual delivery and affected learners. Version numbers and effective dates are therefore part of the statistical record. A new definition of “trained” is not to be presented as a change in teacher preparation unless historical data have been recoded on the same basis.

treatment, statistics, methods, administrative change the practical judgement in revision and statistical independence because the responsible body must identify distribution, timing and remedy. Political or administrative preference cannot determine whether an unfavourable result is published. The Fundamental Principles of Official Statistics provide the relevant basis for professional methods, transparency and confidential treatment of individual data.[REF-11]

explained, exercise, without, both are material to revision and statistical independence only when the record connects the stated measure to actual delivery and affected learners. A census update, payroll cleaning exercise or reclassification may alter prior years without indicating an actual workforce change. Both the revised series and the break explanation are necessary for public interpretation.

school, class, teacher, availability define the evidentiary boundary in scenario construction; aggregate completion cannot substitute for a reasoned account of unequal consequence. It then states class formation or subject-period demand, teacher workload, minimum school staffing, expected availability and replacement assumptions. Only after those choices is the teacher requirement calculated.

case, uses, enrolment, internally define the evidentiary boundary in scenario construction; aggregate completion cannot substitute for a reasoned account of unequal consequence. Each case uses coherent assumptions. Combining high enrolment with low training capacity but leaving vacancies at zero is internally inconsistent.

rapid, 2003, observed, among require the the place of ratio benchmarks analysis to distinguish authority, observed condition and educational effect. The 2003 study of universal primary completion observed an average pupil–teacher ratio of 39:1 among a group of higher-completion low-income countries and used 40:1 in its 2015 costing scenarios. The authors also documented substantial country variation and placed the ratio alongside salaries, repetition, non-salary inputs and finance.[REF-07]

alter, restrained, warrant, matter are material to the place of ratio benchmarks only when the record connects the stated measure to actual delivery and affected learners. Extremely high or low ratios warrant diagnosis, and balanced resource parameters matter. It does not establish a universal optimum. Country geography, school size, curriculum, contact time, teacher preparation and fiscal capacity alter both cost and feasibility.

recruited, bill, allowances, multiplied require the salary bill and complementary inputs analysis to distinguish authority, observed condition and educational effect. Average salary multiplied by teacher count is insufficient where the grade distribution or hardship payments change. Vacancies, arrears and newly recruited cadres are separately shown.

isolation, protected, supervision, salary require the salary bill and complementary inputs analysis to distinguish authority, observed condition and educational effect. The 2003 costing study explicitly protected non-teacher inputs, including materials, development, supervision, assessment and management, because unchecked salary pressure can displace conditions required for effective teaching.[REF-07]

timing, expansion, practicum, induction define the evidentiary boundary in training and transition costs; aggregate completion cannot substitute for a reasoned account of unequal consequence. Rapid change can also require temporary classrooms, teacher housing, transport or additional supervision. These costs have different timing from salaries and must appear in the implementation schedule.

release, fully, period, already define the evidentiary boundary in training and transition costs; aggregate completion cannot substitute for a reasoned account of unequal consequence. Counting the same teacher as fully available for instruction and full-time preparation over the same period overstates capacity.

scenario, horizon, attrition, wage are material to fiscal sustainability only when the record connects the stated measure to actual delivery and affected learners. A scenario therefore reports recurrent cost at the horizon, its share of the relevant public resource envelope and the sensitivity to salary and attrition. External finance may support transition, but an unfunded future wage bill is not a sustainable staffing plan.

domestic, millennium, calls, investment define the evidentiary boundary in fiscal sustainability; aggregate completion cannot substitute for a reasoned account of unequal consequence. Workforce projections serve that procedure when assumptions, sequencing and domestic responsibilities are explicit.[REF-09]

proportion, vacancies, measures, temporary require the national profile analysis to distinguish authority, observed condition and educational effect. It states coverage of non-government provision, temporary staff and missing records.

equalled, assumptions, retained, enough require the national profile analysis to distinguish authority, observed condition and educational effect. A defensible statement identifies the scope: for example, aggregate filled FTE equalled modelled national demand under stated assumptions, while specified districts and subjects retained shortages.

support, level, governed, small require the subnational and school-level use analysis to distinguish authority, observed condition and educational effect. School-level data are used administratively but public release is governed by privacy, data quality and risk of misinterpretation. Small cells concerning qualification, absence or personal characteristics are suppressed or combined.

individual, route, identify, infer define the evidentiary boundary in subnational and school-level use; aggregate completion cannot substitute for a reasoned account of unequal consequence. The responsible authority and correction route accompany material deficiencies.

table, year, time, coverage define the evidentiary boundary in comparability statement; aggregate completion cannot substitute for a reasoned account of unequal consequence. If one country reports headcount and another FTE, direct ranking is withheld or clearly qualified.

able, comparative, institutions, coverage define the evidentiary boundary in comparability statement; aggregate completion cannot substitute for a reasoned account of unequal consequence. A wider coverage can raise or lower a ratio without a change in service. The user is to be able to reconstruct the statistical boundary from the note.

supports, planning, scheduling, integrity change the practical judgement in appropriate and inappropriate uses because the responsible body must identify distribution, timing and remedy. It supports questions, not automatic sanctions.

without, pupil, measure, effectiveness are material to appropriate and inappropriate uses only when the record connects the stated measure to actual delivery and affected learners. It is also inappropriate to compare salary cost without workload and price context.

sensitive, derived, children, care are material to pre-primary provision only when the record connects the stated measure to actual delivery and affected learners. The age of children, duration of sessions, group organisation, care and protection responsibilities, adult support and the boundary between education and other early-childhood services affect the required workforce. Titles and preparation routes also vary, making international teacher counts especially sensitive to classification.

assistants, lies, single, professional define the evidentiary boundary in pre-primary provision; aggregate completion cannot substitute for a reasoned account of unequal consequence. Their contributions are complementary, but merging them into a single denominator obscures both cost and professional preparation. Where sessions are part day, child and staff full-time equivalents require a stated conversion.

exceed, contracts, hours, continuity require the pre-primary provision analysis to distinguish authority, observed condition and educational effect. Headcount can substantially exceed FTE, and annual turnover may be masked by short contracts. A pre-primary profile therefore reports hours, setting type, preparation status and continuity in addition to persons.

every, entry, grades, timing require the primary class-teacher systems analysis to distinguish authority, observed condition and educational effect. National enrolment divided by a ratio is insufficient because every school has grade-specific, integer requirements. Entry expansion first raises demand in early grades and then moves through the cycle; the location and timing of the cohort must be retained.

specific, such, foundational, multi change the practical judgement in primary class-teacher systems because the responsible body must identify distribution, timing and remedy. A teacher qualified for primary education under the national rule may still require specific support for an unfamiliar language or combined-grade assignment. Such support is not represented by the trained-teacher percentage.

stronger, needs, teachers, filled define the evidentiary boundary in primary class-teacher systems; aggregate completion cannot substitute for a reasoned account of unequal consequence. Repeated movement of class teachers can disrupt progression even if each vacancy is filled quickly. The school turnover rate, days without a regular teacher and replacement arrangement provide a stronger account than an annual vacancy snapshot.

pupils, teachers, assessment, offset are material to lower-secondary subject transition only when the record connects the stated measure to actual delivery and affected learners. The same pupils generate several subject-period requirements, and teachers' timetables contain non-contact preparation and assessment time. A national surplus in one subject does not offset a shortage in another.

needs, balance, secondary, loads define the evidentiary boundary in lower-secondary subject transition; aggregate completion cannot substitute for a reasoned account of unequal consequence. Permissible solutions include teachers prepared across related fields, coordinated timetables across nearby schools and carefully scheduled itinerant provision. Every solution requires a valid subject-match rule and travel or coordination time. Treating fractional needs as nationally poolable can produce a calculated balance that no timetable can operate.

hiring, conditions, workforce, expansion change the practical judgement in lower-secondary subject transition because the responsible body must identify distribution, timing and remedy. Hiring subject teachers without the enabling conditions may increase payroll but not the intended curriculum. Workforce and non-salary planning remain connected.

secondary, staffing, level, outside are material to upper-secondary and vocational programmes only when the record connects the stated measure to actual delivery and affected learners. Occupational expertise may be acquired outside the teacher-training route, while pedagogical preparation remains relevant. The register is to preserve both dimensions instead of classifying all specialists as trained or untrained through one field.

expertise, contributes, across, supervision are material to upper-secondary and vocational programmes only when the record connects the stated measure to actual delivery and affected learners. Their headcount is a poor measure of capacity if each contributes few periods. FTE, timetable availability and continuity across the programme are necessary. Equipment safety and supervision can also set minimum staffing independent of enrolment.

because, programme, create, transferable define the evidentiary boundary in upper-secondary and vocational programmes; aggregate completion cannot substitute for a reasoned account of unequal consequence. Redeployment scenarios state the additional preparation required and do not count a person as immediately deployable merely because an employment post remains funded.

employed, routes, required, separately are material to rapid expansion after policy change only when the record connects the stated measure to actual delivery and affected learners. The first-year plan identifies teachers already qualified but not employed, possible re-entrants, lawful temporary routes, deployable staff and the training capacity required for later years. Each source is reported separately because its cost and sustainability differ.

monitoring, growth, district, distributional are material to rapid expansion after policy change only when the record connects the stated measure to actual delivery and affected learners. New posts may be filled first in accessible areas, leaving the intended beneficiaries with larger classes or less-prepared staff. Monitoring therefore compares the pace of enrolment growth, post creation, appointment and arrival by district and school.

until, transition, explicit, documents change the practical judgement in rapid expansion after policy change because the responsible body must identify distribution, timing and remedy. The planning implication is not to delay access until every input is ideal; it is to make the transition condition, duration and corrective path explicit.[REF-07]

records, deployment, rapidly, necessary are material to conflict, displacement and institutional interruption only when the record connects the stated measure to actual delivery and affected learners. Historic establishment figures rapidly lose relevance. A temporary register may be necessary, but it records the source and verification status of each entry so that emergency data do not become an unexamined permanent payroll.

location, term, safe, require change the practical judgement in conflict, displacement and institutional interruption because the responsible body must identify distribution, timing and remedy. Minimum service, safe access, language and psychosocial conditions may require staffing arrangements not captured by ordinary ratios. Teachers themselves may be displaced and require recognition of prior service or credentials where records can be verified.

gaps, endanger, handled, school require the conflict, displacement and institutional interruption analysis to distinguish authority, observed condition and educational effect. Publishing exact teacher or school locations can create risk. Public accountability can report aggregate coverage and service gaps without releasing operational details that endanger staff or pupils.

At the 2011 cut-off, HIV/AIDS constitutes a material workforce and pupil-planning concern in heavily affected countries. The 2003 costing study identifies sickness-related absence, teacher mortality, replacement recruitment, training demand and increased numbers of orphans requiring support as connected consequences. It estimates costs through explicit epidemiological and demographic assumptions rather than treating the epidemic as a general narrative risk.[REF-07]

planning, health, statistics, absence require the hiv/aids and workforce continuity analysis to distinguish authority, observed condition and educational effect. Individual health status is not needed for routine teacher statistics and must not be inferred. Mortality and long-term absence data may inform projections when collected lawfully; workplace support, leave and replacement are handled through applicable employment and health arrangements.

tests, without, experienced, preferable define the evidentiary boundary in hiv/aids and workforce continuity; aggregate completion cannot substitute for a reasoned account of unequal consequence. The projection states mortality, long-absence and replacement assumptions and varies them within evidence-based ranges. It also tests the training system's ability to replace losses without lowering preparation standards or stripping experienced staff from training roles.

single, geographic, efficiency, least require the remote, island and sparsely populated systems analysis to distinguish authority, observed condition and educational effect. A school or island may require at least one teacher even when enrolment is very low. National ratios can then appear favourable while the system faces high unit costs, single-teacher vulnerability and limited curriculum breadth.

staff, notes, movement, model change the practical judgement in remote, island and sparsely populated systems because the responsible body must identify distribution, timing and remedy. The 2003 costing study expressly notes that low population density and geography can make movement towards a common ratio difficult. A model that ignores this constraint turns legitimate access cost into apparent inefficiency.[REF-07]

greater, elsewhere, teacher, falls are material to remote, island and sparsely populated systems only when the record connects the stated measure to actual delivery and affected learners. If a one-teacher school loses its teacher, instructional capacity falls to zero. A modest system-level substitute pool, housing provision, scheduled relief and cluster support may have greater service value than reducing the nominal ratio elsewhere.

pupils, describe, legal, funding are material to non-government and community provision only when the record connects the stated measure to actual delivery and affected learners. Coverage is to follow the legal and statistical mandate and is clearly labelled. Public funding, employment responsibility and data reporting are separate questions.

regularity, inclusion, employment, supported define the evidentiary boundary in non-government and community provision; aggregate completion cannot substitute for a reasoned account of unequal consequence. Their workload, preparation, payment regularity and continuity still affect pupils. Inclusion in statistics must not be presented as a change in governmental employment status or an endorsement of employment conditions.

population, stated, teacher, person change the practical judgement in non-government and community provision because the responsible body must identify distribution, timing and remedy. Person headcount is consolidated within the defined population, while assignment FTE is allocated to each sector under a stated rule.

information, accountable, correct, unauthorised change the practical judgement in decentralised responsibility because the responsible body must identify distribution, timing and remedy. The national information system must therefore distinguish who owns the record and who is accountable for each transition. A central payroll cannot correct a local timetable; a school cannot fund an unauthorised post.

coverage, national, exchange, local are material to decentralised responsibility only when the record connects the stated measure to actual delivery and affected learners. Local systems can retain operational detail while submitting a controlled set of person, post, assignment and school records. The central publication reports coverage and late or non-reporting authorities.

exceptions, otherwise, legitimate, treatment require the decentralised responsibility analysis to distinguish authority, observed condition and educational effect. Otherwise, variation in ratios cannot be separated into legitimate adaptation, historical allocation or unequal treatment.

fifth, unresolved, establish, valid change the practical judgement in a sequenced national programme because the responsible body must identify distribution, timing and remedy. The second phase is diagnostic: calculate stock, flow, deployment and time measures with uncertainty. The third phase is projection: connect pupil demand, curriculum, workload and exits. The fourth phase is implementation: align training, recruitment, deployment, conditions and finance. The fifth phase is public review: publish results, revisions and unresolved gaps.

persist, sequence, repair, codes change the practical judgement in a sequenced national programme because the responsible body must identify distribution, timing and remedy. A sophisticated projection cannot repair duplicated persons or invalid school codes. Equally, data cleaning without a decision purpose can consume capacity while vacancies persist. Each data improvement is tied to a planning decision it enables.

districts, govern, classifications, responsibility define the evidentiary boundary in institutional responsibilities; aggregate completion cannot substitute for a reasoned account of unequal consequence. Finance authorities control funding and payroll; employer authorities control appointments; districts and schools confirm assignment and service; training authorities govern preparation; statistical offices maintain classifications and publication standards. A written data-responsibility schedule is therefore required.

consultation, improves, professional, hold are material to institutional responsibilities only when the record connects the stated measure to actual delivery and affected learners. Teachers and their organisations hold evidence about workload, feasibility, rural conditions and the consequences of timetable rules. Consultation does not replace governmental responsibility; it improves the factual basis and legitimacy of decisions.[REF-02]

designs, counterfactuals, research, instructional define the evidentiary boundary in research priorities at the 2011 cut-off; aggregate completion cannot substitute for a reasoned account of unequal consequence. Evaluation designs need comparison groups or credible counterfactuals where causal claims are intended.

attrition, detail, credentials, definitions require the research priorities at the 2011 cut-off analysis to distinguish authority, observed condition and educational effect. Harmonisation is valuable where it preserves national detail and does not imply that differently constituted credentials are equal.

reference, consistently, planning, shortage require the limitations analysis to distinguish authority, observed condition and educational effect. Several sources use different reference years, and school-level distributions are not consistently available. This report therefore provides a measurement and planning architecture rather than a new global estimate of teacher shortage.

behaviour, visible, curriculum, remove are material to limitations only when the record connects the stated measure to actual delivery and affected learners. It cannot remove uncertainty from demographic projection or predict individual behaviour. It can require that these choices and uncertainties be visible.

designs, examining, descriptive, nationally require the limitations analysis to distinguish authority, observed condition and educational effect. Differences in pupil–teacher ratios, nationally defined preparation status, reported presence or completion do not isolate the effect of one workforce condition from finance, pupil composition, curriculum, school organisation or wider social circumstances. The report therefore does not estimate a causal return to recruitment, class-size change, qualification reform or attendance control. Those questions require designs capable of distinguishing the intervention from concurrent change and of examining implementation over time.

subject, documented, planning, aggregate change the practical judgement in limitations because the responsible body must identify distribution, timing and remedy. National and regional aggregates can indicate where further inquiry is required, but they cannot reveal every school, subject or population gap. Conversely, a small number of documented local cases cannot establish a national pattern. The planning method addresses this limitation by moving from aggregate signal to reconciled school and timetable evidence before an allocation decision is made. Where such evidence is absent, the limitation is a reason to narrow the conclusion, not to substitute an assumed distribution.

cannot, national, definition, teach define the evidentiary boundary in conclusion; aggregate completion cannot substitute for a reasoned account of unequal consequence. Headcount alone cannot establish that condition. Neither can a favourable national ratio, a training credential without its definition, or a funded post without a person present to teach.

chain, necessary, correct, project change the practical judgement in conclusion because the responsible body must identify distribution, timing and remedy. Where the chain breaks, the break is the planning finding.

instructional, protects, teacher, resources change the practical judgement in conclusion because the responsible body must identify distribution, timing and remedy. A system that makes missing assignments, unresolved vacancies, unequal deployment and lost instructional time visible is better placed to act than one that protects an aggregate appearance of balance.

otherwise, stated, date, person define the evidentiary boundary in general conventions; aggregate completion cannot substitute for a reasoned account of unequal consequence. “Teacher” denotes a person assigned to direct instruction under the applicable national and international statistical definition. Mixed-function staff are apportioned in FTE measures where valid workload data exist; otherwise they are separately classified.

suppression, denominators, coverage, population define the evidentiary boundary in general conventions; aggregate completion cannot substitute for a reasoned account of unequal consequence. Percentages are not calculated where coverage is materially incomplete unless the covered population is explicit. Results are rounded only after calculation. Suppression for confidentiality is not treated as zero.

part, material, sector, unavailable define the evidentiary boundary in denominator control; aggregate completion cannot substitute for a reasoned account of unequal consequence. Where pupil FTE is unavailable, headcount-based ratios are labelled accordingly. Boarding, distance and part-year participation rules are disclosed where material.

includes, percentage, stock, expected are material to denominator control only when the record connects the stated measure to actual delivery and affected learners. For absence observation, the denominator contains persons expected at the observed time, not all employees.

district, unless, ratios, weighted define the evidentiary boundary in distribution control; aggregate completion cannot substitute for a reasoned account of unequal consequence. Pupil-weighted exposure attaches each pupil to the ratio of the school attended. District aggregates are calculated from district totals rather than averaging school ratios unless the statistic is expressly the mean school ratio.

For level (l), location (g), subject or function (s), and period (t):

T_{lgs,t+1}=T_{lgs,t}+E_{lgs,t}+R_{lgs,t}+M^{in}_{lgs,t}-A_{lgs,t}-M^{out}_{lgs,t}+C_{lgs,t}

where (T) is stock, (E) first entry, (R) re-entry, (M) transfer or migration, (A) attrition and (C) verified correction. Every term uses the same headcount or FTE basis.

appointments, positive, exits, entry change the practical judgement in recruitment requirement because the responsible body must identify distribution, timing and remedy. Candidate completions required equal appointments divided by expected appointment yield. If preparation completion yield is below one, admissions required are calculated separately using a cohort model.

grade, quotient, formation, rules change the practical judgement in class-based demand because the responsible body must identify distribution, timing and remedy. Aggregation occurs after school calculation. Rounding only after national aggregation understates demand where many small residual classes exist.

cannot, travel, required, full define the evidentiary boundary in period-based demand; aggregate completion cannot substitute for a reasoned account of unequal consequence. Fractional needs cannot automatically be pooled across schools where travel makes schedules incompatible.

divides, loss, adjustment, avoidable are material to availability adjustment only when the record connects the stated measure to actual delivery and affected learners. The adjustment is scenario-specific. It is not a licence to normalise avoidable absence; improvement cases show the workforce and service consequences of reducing preventable loss.

based, identify, biographical, time require the identity and duplication analysis to distinguish authority, observed condition and educational effect. Matches are reviewed; rule-based flags do not determine identity.

period, both, precede, valid are material to temporal validity only when the record connects the stated measure to actual delivery and affected learners. Assignment, qualification and employment statuses are valid on the reference date. A school code is active for the same period. Transactions entered late retain both event and entry dates.

exceeds, documented, teacher, assignment define the evidentiary boundary in internal consistency; aggregate completion cannot substitute for a reasoned account of unequal consequence. Timetable periods do not overlap. Teacher level and subject codes are compatible with the assignment rule or carry a mismatch status. Funded vacancies cannot exceed funded establishment.

records, establishment, coverage, statement change the practical judgement in external reconciliation because the responsible body must identify distribution, timing and remedy. Differences are classified by timing, coverage, definition or unresolved error. A reconciliation statement reports both counts and the number resolved.

attrition, yield, price, contains define the evidentiary boundary in required assumptions; aggregate completion cannot substitute for a reasoned account of unequal consequence.

attrition, yield, grade, redistribution define the evidentiary boundary in sensitivities; aggregate completion cannot substitute for a reasoned account of unequal consequence. Where salary expenditure is material, salary growth and grade distribution are varied. Where remoteness is material, the feasibility of redistribution and the cost of minimum schools are tested.

identifies, responsible, results, scenario are material to decision record only when the record connects the stated measure to actual delivery and affected learners. It names the authority responsible for each implementation condition and the date on which actual results will be compared with the projection.

combined, sampling, region, probability define the evidentiary boundary in sampling; aggregate completion cannot substitute for a reasoned account of unequal consequence. Probability selection supports system inference. Purposeful visits can investigate known risks but are not combined with probability estimates without appropriate weighting.

anticipation, persons, operating, absence define the evidentiary boundary in observation; aggregate completion cannot substitute for a reasoned account of unequal consequence. They do not classify the reason for absence without subsequent verification. Visit date and time are protected during fieldwork to reduce anticipation.

competent, preserved, classifications, discrepancies are material to verification and response only when the record connects the stated measure to actual delivery and affected learners. Individual due procedure is preserved. The statistical report uses aggregate, reviewed classifications and states the share unresolved.

instruction, authorised, available, observation define the evidentiary boundary in ethical controls; aggregate completion cannot substitute for a reasoned account of unequal consequence. Observation does not intrude on instruction beyond what is necessary. Data are retained only for the authorised purpose, with access limited and correction available.

definitions, tables, exceed, statistical are material to release checklist only when the record connects the stated measure to actual delivery and affected learners.

called, teaching, absence, balance require the interpretation checklist analysis to distinguish authority, observed condition and educational effect.

distribution, verified, rhetorically, estimate are material to final interpretive position only when the record connects the stated measure to actual delivery and affected learners. It requires a result matched to the strength of evidence. A verified national headcount may be published as headcount; it is not converted rhetorically into classroom availability. A sampled presence estimate may inform system planning; it is not used to declare individual fault.

reader, funds, recorded, complete are material to final interpretive position only when the record connects the stated measure to actual delivery and affected learners. That standard protects teachers from unsupported inference, protects public funds from false reconciliation and protects pupils from the assumption that a recorded post is the same as instruction received.

draw, whether, schools, exercise define the evidentiary boundary in purpose and boundary; aggregate completion cannot substitute for a reasoned account of unequal consequence. It is not a general reduction exercise. Its reference population comprises every active school and programme within the stated sector, together with central or district teaching-support functions that draw from the same occupational establishment.

periods, specialised, compares, funded require the purpose and boundary analysis to distinguish authority, observed condition and educational effect. For each school it records projected pupils, grades, classes, curriculum periods, approved school hours, leadership arrangements, specialised obligations and justified minimum staffing. It then compares calculated entitlement, authorised posts, funded posts, filled FTE and assigned instructional FTE.

remain, without, extract, selected change the practical judgement in baseline freeze and transaction window because the responsible body must identify distribution, timing and remedy. Appointments, transfers, exits and school changes occurring after that date remain in a transaction window and are not mixed into the snapshot. Without this separation, a person may appear at an old school in the personnel extract and at a new school in the school census.

final, produces, frozen, continue define the evidentiary boundary in baseline freeze and transaction window; aggregate completion cannot substitute for a reasoned account of unequal consequence. It is frozen statistically so that every comparison refers to a reproducible point. The final review applies validated transactions and produces a second dated position.

small, carry, entitlement, auditable require the entitlement calculation analysis to distinguish authority, observed condition and educational effect. It specifies upward rounding, treatment of combined grades, leadership release, subjects, shifts, small schools and travelling staff. Exceptions carry an authority, reason and expiry or review date.

without, organisation, reviewed, before are material to entitlement calculation only when the record connects the stated measure to actual delivery and affected learners. Applying a national ratio first can suppress the indivisible staffing requirements of small schools. Conversely, school-level calculation without a rule for feasible multi-grade organisation can overstate need. Both the entitlement and its educational assumptions are reviewed.

below, classification, lacking, nevertheless define the evidentiary boundary in comparison states; aggregate completion cannot substitute for a reasoned account of unequal consequence. A second classification tests subject, grade and qualification fit. A school at aggregate entitlement but lacking a teacher for a required subject is not fully staffed. A school above aggregate entitlement may nevertheless have a justified minimum or a mismatch that prevents redistribution.

staffing, fractions, language, expected change the practical judgement in treatment of apparent surplus because the responsible body must identify distribution, timing and remedy. The review tests minimum school staffing, actual timetable, part-time fractions, impending retirement, approved leave, language or specialist functions, travel feasibility and expected enrolment. Only the remaining deployable excess enters a redistribution scenario.

scenario, immediately, disrupt, vacancy change the practical judgement in treatment of apparent surplus because the responsible body must identify distribution, timing and remedy. A scenario that counts every numerical surplus as immediately movable overstates implementation capacity and can disrupt schools without filling the target vacancy.

adjustment, recruitment, several, such are material to treatment of shortage only when the record connects the stated measure to actual delivery and affected learners. A timetable adjustment may resolve a fractional subject gap within a term; recruitment may require a year; preparation of new teachers may require several years. Temporary measures are identified as such and carry an end condition.

unrecorded, resources, part, plan are material to treatment of shortage only when the record connects the stated measure to actual delivery and affected learners. Shortage caused by a genuine service obligation becomes part of the recruitment, deployment or school-organisation plan.

calculation, correction, against, while define the evidentiary boundary in review safeguards; aggregate completion cannot substitute for a reasoned account of unequal consequence. The review distinguishes correction of fact from appeal against policy. Aggregate findings are published with methods, while personal records remain protected.

teaching, phase, transitional, reference require the qualification rule register analysis to distinguish authority, observed condition and educational effect. Historical records are evaluated under the rule applicable at the reference date unless the policy question expressly requires current status.

analytical, decline, teachers, time change the practical judgement in qualification rule register because the responsible body must identify distribution, timing and remedy. Time-series publication therefore provides both the legal-definition series and, where feasible, a constant-definition analytical series. It does not describe the discontinuity as improvement or decline in capability.

identity, teacher, applies, cases are material to credential verification only when the record connects the stated measure to actual delivery and affected learners. It does not evaluate the quality of an individual teacher. Where original records are unavailable, the competent authority applies a documented alternative-evidence procedure. Pending cases remain pending or unknown.

subject, national, jurisdiction, recognition require the credential verification analysis to distinguish authority, observed condition and educational effect. The statistical office does not infer equivalence from title similarity. Recognition for employment and evidence of subject preparation are maintained as separate fields where national rules distinguish them.

fields, full, requiring, dated are material to match matrix only when the record connects the stated measure to actual delivery and affected learners. It may contain full match, accepted related field, provisional match requiring support, and no established match. The matrix is level-specific and dated. Broad occupation codes are not sufficient.

duration, activity, unless, result require the in-service preparation analysis to distinguish authority, observed condition and educational effect. Attendance at a short activity does not alter trained status unless the national rule expressly provides that result. Professional development is analysed as continuing preparation rather than a substitute label for initial qualification.

time, occurs, rescheduling, future are material to in-service preparation only when the record connects the stated measure to actual delivery and affected learners. If training occurs during scheduled instruction, the replacement or rescheduling arrangement is recorded. A programme can strengthen future capacity while temporarily reducing current contact time; both effects belong in the plan.

teaching, competence, identifies, rule require the interpretation analysis to distinguish authority, observed condition and educational effect. It does not prove command of content, pedagogy or pupil learning. Conversely, a mismatch classification does not prove ineffective teaching: experienced teachers may have acquired substantial competence outside the recognised route. The measure identifies a planning and support question under the governing rule.

once, delivered, primary, opportunities are material to estimand only when the record connects the stated measure to actual delivery and affected learners. Alternative estimands include the proportion of teachers absent at least once across visits, the proportion of scheduled periods delivered and the proportion of pupil-hours lost. They are not interchangeable.

visit, assigned, excluded, constructed define the evidentiary boundary in estimand; aggregate completion cannot substitute for a reasoned account of unequal consequence. Persons not scheduled at that time, no longer assigned, or lawfully working at another location are excluded from “expected” only after verification.

small, exposure, sampling, selected change the practical judgement in sampling unit and weighting because the responsible body must identify distribution, timing and remedy. Selection probabilities are retained. Estimates use weights and account for clustering. A simple mean across visited schools can overrepresent small schools if the target is teacher opportunities or pupil exposure.

weight, sample, level, ensure require the sampling unit and weighting analysis to distinguish authority, observed condition and educational effect. Oversampled strata are returned to their population weight for national estimates. Separate estimates are published only where sample size supports them.

behaviour, rate, persistent, visits require the visit frequency analysis to distinguish authority, observed condition and educational effect. Repeated visits permit analysis of recurrence and seasonality. The interval and visit window are chosen without creating a predictable schedule that changes behaviour.

remains, verified, cases, schedule define the evidentiary boundary in reason verification; aggregate completion cannot substitute for a reasoned account of unequal consequence. A separate verification procedure checks authorised leave, training, official duty and assignment. “Unknown reason” remains a result where evidence is not available. The analysis can report total absence and the verified distribution of reasons without converting unknown cases into unauthorised absence.

substitution, inaccessible, classification, enters require the non-response and closure analysis to distinguish authority, observed condition and educational effect. If closure is itself part of service availability, it enters the appropriate estimate. Security or access non-response is reported and may require adjustment; substitution with an easier school can bias results.

allege, field, sampling, visit require the reporting conduct analysis to distinguish authority, observed condition and educational effect. Preliminary results are labelled. The report does not publish names or use a system estimate to allege individual misconduct.

estimated, enrolment, feasibility, distribution are material to rapid primary-entry expansion only when the record connects the stated measure to actual delivery and affected learners. The immediate requirement is estimated by school and grade, not by applying a national ratio to total enrolment. Existing classrooms, double-shift feasibility, teacher candidates already prepared and the distribution of growth determine what can open on time.

classroom, permanently, expansion, differ change the practical judgement in rapid primary-entry expansion because the responsible body must identify distribution, timing and remedy. A one-year entry bulge progresses through the cycle; its teacher and classroom requirement moves by grade. If participation remains permanently higher, later cohorts sustain the expansion. Recruitment, preparation and budget profiles differ between these cases.

primary, expansion, unqualified, preparation change the practical judgement in rapid primary-entry expansion because the responsible body must identify distribution, timing and remedy. The experience documented in the 2003 universal-primary-education study, including instances where rapid expansion raised ratios and increased reliance on unqualified teachers, shows why access and workforce preparation must be costed together.[REF-07]

road, skills, presence, ratios require the small remote school cluster analysis to distinguish authority, observed condition and educational effect. A national efficiency screen might identify surplus. The appropriate analysis maps travel time, road seasonality, grade combinations, teacher skills, community access and the minimum adult presence required.

saved, shared, infeasible, closure define the evidentiary boundary in small remote school cluster; aggregate completion cannot substitute for a reasoned account of unequal consequence. Closure or consolidation is not treated as a staffing calculation alone because distance can exclude children. The scenario compares service received, not only FTE saved.

match, assignments, surplus, mathematics change the practical judgement in secondary subject imbalance because the responsible body must identify distribution, timing and remedy. Person counts cannot resolve the conflict. Timetables are converted into subject periods, credentials are mapped under the match matrix, and feasible cross-school assignments are tested.

post, responses, timetable, lead define the evidentiary boundary in secondary subject imbalance; aggregate completion cannot substitute for a reasoned account of unequal consequence. Each has lead time and quality conditions. Redeploying an unmatched surplus into a vacancy changes the post count but not subject-matched capacity.

eligibility, actual, admissions, duration are material to ageing workforce only when the record connects the stated measure to actual delivery and affected learners. The projection uses actual eligibility and observed retirement timing, not age alone. Candidate admissions are increased early enough to account for preparation duration and completion yield.

supported, because, weaken, arrangements are material to ageing workforce only when the record connects the stated measure to actual delivery and affected learners. Phased retirement or return arrangements are modelled only if legally available and supported by evidence of uptake.

sanction, official, delays, school require the high recorded absence analysis to distinguish authority, observed condition and educational effect. Before sanction or additional recruitment, the authority verifies leave, official duties, training schedules, payment delays, housing, travel and replacement. It also examines school closure and delivered periods.

rate, according, training, reserve require the high recorded absence analysis to distinguish authority, observed condition and educational effect. If assignment records are wrong, the response is reconciliation. If unexplained recurrent absence remains after due procedure, employment controls may apply. The same rate can therefore lead to different action according to cause.

tests, leave, functions, waste require the payroll growth without instructional growth analysis to distinguish authority, observed condition and educational effect. Reconciliation tests central assignments, new leadership release, leave, delayed deployment, duplicates and expansion in non-school functions. The finding is not automatically payroll fraud or administrative waste.

remains, enter, planning, explained change the practical judgement in payroll growth without instructional growth because the responsible body must identify distribution, timing and remedy. Only validated instructional assignments enter the pupil–teacher ratio used for service planning.

recorded, prevents, keeps, cases are material to case conclusion only when the record connects the stated measure to actual delivery and affected learners. Each begins by selecting the unit appropriate to the decision and tracing the point at which recorded resources cease to be deployable service. This discipline prevents ratio targets from substituting for diagnosis and keeps administrative action proportionate to evidence.

teachers, payroll, rather, change require the base-year reconstruction analysis to distinguish authority, observed condition and educational effect. Opening pupil and teacher stocks refer to the same school year and education boundary. Late census returns, duplicate schools, teachers assigned outside the level and unresolved payroll records are identified. A base-year adjustment is documented rather than silently absorbed into the first projected change.

constraints, grade, teacher, employment change the practical judgement in base-year reconstruction because the responsible body must identify distribution, timing and remedy. Teacher stocks are held by person, FTE, assignment, subject or grade capability and employment status. Aggregation is delayed until the organisational constraints have been applied.

derived, estimated, reconciled, explicit require the pupil-flow component analysis to distinguish authority, observed condition and educational effect. New entrants are derived from the relevant age population and entry assumptions or from a separately estimated intake series. The sum of outcomes for a grade cohort is reconciled to the opening cohort, with migration and record corrections explicit.

case, invented, fewer, disclosed require the pupil-flow component analysis to distinguish authority, observed condition and educational effect. A gross-enrolment trend does not permit precise grade-flow projection. In that case, broader demand ranges are preferable to invented transition rates.

pupils, level, combined, multiplied define the evidentiary boundary in class and period formation; aggregate completion cannot substitute for a reasoned account of unequal consequence. The upward-rounding rule is applied, and approved combined-grade arrangements are incorporated. For specialist teaching, classes are multiplied by curriculum periods by subject. The resulting timetable demand is checked against the total prescribed instructional period.

separate, distribution, unchanged, solely define the evidentiary boundary in class and period formation; aggregate completion cannot substitute for a reasoned account of unequal consequence. A new school changes minimum staffing and distribution even if total enrolment remains unchanged. Consolidation changes travel and access and is not introduced solely as an arithmetic means to reduce FTE.

both, genuinely, group, first change the practical judgement in teacher-flow component because the responsible body must identify distribution, timing and remedy. First entry, re-entry, retirement, resignation, mortality, dismissal, transfer and workload change have separate rates or counts. The model prevents a transfer between districts from becoming both a national exit and entry unless the national boundary genuinely changes.

candidate, programme, share, case define the evidentiary boundary in teacher-flow component; aggregate completion cannot substitute for a reasoned account of unequal consequence. Candidate cohorts complete after the applicable programme duration, and only the expected eligible and appointed share reaches the teacher stock. An unconstrained recruitment case may be shown to describe need, but the operational case cannot recruit more candidates than the pathway can supply.

subject, limits, between, reported require the deployment component analysis to distinguish authority, observed condition and educational effect. Perfect allocation is not assumed. Historical vacancy duration, subject scarcity, geographic constraints and transfer limits inform the deployable share. The difference between total supply and feasible deployment is reported.

immediate, consultation, identifies, minimum are material to deployment component only when the record connects the stated measure to actual delivery and affected learners. The model records the year in which movement can occur. Immediate transfer at the base date is not assumed when consultation and notice are required.

every, school, sequence, twice define the evidentiary boundary in instructional-capacity component; aggregate completion cannot substitute for a reasoned account of unequal consequence. The sequence is defined to avoid applying the same loss twice. Where only one availability estimate exists, scenarios use an interval and do not distribute identical absence mechanically to every school.

without, hours, outside, separately require the instructional-capacity component analysis to distinguish authority, observed condition and educational effect. Pupil-received hours additionally require pupil attendance; this lies outside the teacher-stock equation and is reported separately.

components, unchanged, coding, model require the back-testing analysis to distinguish authority, observed condition and educational effect. Differences are decomposed into demographic, enrolment, attrition, recruitment, deployment and data-revision components. Back-testing does not validate an unchanged future, but it reveals unstable assumptions and coding errors.

release, version, overwrite, distinguish require the version control analysis to distinguish authority, observed condition and educational effect. A new release does not overwrite the prior scenario. Decision-makers can therefore distinguish a changed outlook from a changed model or revised baseline.

able, national, preserving, league require the purpose analysis to distinguish authority, observed condition and educational effect. It is not a league table. Its purpose is to locate service constraints, determine whether they are widespread or concentrated and identify the authority able to respond.

contains, vacancies, availability, module require the common core and contextual module analysis to distinguish authority, observed condition and educational effect. The contextual module records remoteness, school size, language, conflict or displacement, shift operation and other conditions relevant to interpretation.

contextual, necessarily, avoidable, common change the practical judgement in common core and contextual module because the responsible body must identify distribution, timing and remedy. Contextual variables explain why equal ratios do not necessarily imply equal provision. They are not used to excuse avoidable inequality without evidence.

permits, vary, therefore, distribution change the practical judgement in geographic unit because the responsible body must identify distribution, timing and remedy. Publication therefore includes both administrative aggregates and school-distribution statistics. Boundary changes are versioned; historical values are recast only where the source permits a defensible mapping.

counting, national, ratios, exist require the geographic unit analysis to distinguish authority, observed condition and educational effect. Counting the full person in each region inflates the national total. Pupils are assigned to the school attended for service ratios and to residence for access analysis where both data exist.

category, pupil, schools, girls are material to equity stratification only when the record connects the stated measure to actual delivery and affected learners. The stratifier must be measured at the appropriate unit. A district poverty category is not treated as a household characteristic for every pupil.

combined, need, identify, cells are material to equity stratification only when the record connects the stated measure to actual delivery and affected learners. Small groups are combined or suppressed, and suppression does not erase the need for administrative response. Narrative findings can identify a protected service gap without publishing identifiable cells.

does, typology, planning, growth define the evidentiary boundary in regional typology; aggregate completion cannot substitute for a reasoned account of unequal consequence. Grouping is based on disclosed variables and does not replace the published underlying measures.

assistance, typologies, category, value are material to regional typology only when the record connects the stated measure to actual delivery and affected learners. They are not institutional labels or permanent judgements. Their value lies in matching technical assistance and planning tools to a documented problem.

result, staff, reflect, enrolment change the practical judgement in outlier review because the responsible body must identify distribution, timing and remedy. A very low ratio may result from a small denominator, closure, duplicated staff or justified minimum provision. A very high ratio may reflect missing teachers, double shifts or an enrolment surge. The validated value remains in the distribution; it is not removed merely because it is inconvenient.

begins, limitation, region, magnitude are material to narrative standard only when the record connects the stated measure to actual delivery and affected learners. It avoids adjectives of praise or blame. Where a region differs from the national result, the report identifies the magnitude, period and relevant context. Recommendations are assigned to the authority with the competence and resources to act.

staffing, housing, expenditure, salary are material to cost boundary only when the record connects the stated measure to actual delivery and affected learners. Capital costs such as housing or new training facilities are separated from recurrent expenditure.

price, nominal, financed, affects change the practical judgement in cost boundary because the responsible body must identify distribution, timing and remedy. Nominal and real series are not mixed. Foreign-financed and domestically financed components are separately visible where this affects sustainability, without implying that one source changes the educational value of the input.

year, salary, multiplying, change define the evidentiary boundary in salary calculation; aggregate completion cannot substitute for a reasoned account of unequal consequence. Entry cohorts begin at their applicable point; promotions, increments and retirement alter the distribution over time. Part-year appointment and vacancy timing are included.

absence, allowances, including, legally define the evidentiary boundary in salary calculation; aggregate completion cannot substitute for a reasoned account of unequal consequence. An allowance that is legally due but historically delayed remains a liability; its absence from cash execution is not an efficiency saving.

facilities, nominally, places, completions change the practical judgement in preparation cost because the responsible body must identify distribution, timing and remedy. If the completion yield is 80 per cent, funding only the number of eventual appointments as entrants understates capacity. Practicum, instructor supply and facilities can constrain expansion even when funds are nominally available.

rather, candidate, access, model require the preparation cost analysis to distinguish authority, observed condition and educational effect. The model records these as policy components rather than burying them in an average training cost.

exercises, appointment, part, underspending are material to recruitment and induction only when the record connects the stated measure to actual delivery and affected learners. Large recruitment exercises also require processing capacity. Delayed appointment can leave funded posts vacant for part of the school year, producing apparent underspending and real service loss.

time, payment, existing, workload require the recruitment and induction analysis to distinguish authority, observed condition and educational effect. Its cost can appear as release time or additional staffing rather than a cash payment. Excluding it assumes that induction has no effect on existing instructional capacity.

receipt, transport, required, provides require the deployment supports analysis to distinguish authority, observed condition and educational effect. The 1966 Recommendation provides an international basis for attention to accommodation, travel and hardship in remote areas. The finance model tests receipt and retention, not announcement alone.[REF-02]

supports, planning, allocation, states define the evidentiary boundary in deployment supports; aggregate completion cannot substitute for a reasoned account of unequal consequence. The education budget records only its share where an agreed allocation exists; the staffing scenario nevertheless states the dependency.

regard, 2003, share, role are material to complementary educational inputs only when the record connects the stated measure to actual delivery and affected learners. The 2003 universal-primary-education model used a distinct share for inputs other than teacher salaries and explained their role in quality and system management.[REF-07]

universal, show, whether, amount require the complementary educational inputs analysis to distinguish authority, observed condition and educational effect. It requires the scenario to show what remains after workforce costs and whether the curriculum and professional support can operate within that amount.

share, liability, context, large change the practical judgement in fiscal indicators because the responsible body must identify distribution, timing and remedy. These measures require context; a high salary share can reflect underfunded non-salary inputs, large staff need or narrow accounting coverage.

cost, time, wage, without require the fiscal indicators analysis to distinguish authority, observed condition and educational effect. It is an efficiency diagnostic, not a wage judgement, and is not compared across systems without price, workload and curriculum context.

cannot, financing, plan, resources define the evidentiary boundary in financing gap; aggregate completion cannot substitute for a reasoned account of unequal consequence. Aspirational funds are not counted as available. A gap can be reduced by additional finance, changed sequencing or genuine efficiency improvement; it cannot be removed by omitting required costs.

plan, period, horizon, projected are material to sustainability test only when the record connects the stated measure to actual delivery and affected learners. Sensitivity tests cover salary, exchange-rate exposure where relevant, attrition and enrolment. A plan that can be financed only during the initial project period is identified as transitional and requires a continuation decision.

current, replace, personnel, workload are material to personnel event record only when the record connects the stated measure to actual delivery and affected learners. Appointment, confirmation, workload change, qualification recognition, assignment, leave, return, promotion, transfer and exit are separate dated events. A current-status table may be derived from them, but it does not replace the history required for stock-and-flow analysis.

prior, corrected, access, records require the personnel event record analysis to distinguish authority, observed condition and educational effect. Corrections identify the field corrected and retain the superseded value under controlled access. Deletion is restricted to invalid duplicate records and remains auditable.

transferred, opened, post, function require the post record analysis to distinguish authority, observed condition and educational effect. A post transferred between schools is closed at the origin and opened or reauthorised at the destination; its history is not overwritten.

definition, permanent, linked, workload define the evidentiary boundary in post record; aggregate completion cannot substitute for a reasoned account of unequal consequence. A person can be linked to more than one fractional post, but the combined workload control applies. A post without a person is a vacancy only if it is funded and available for filling under the stated definition.

census, date, grades, absence define the evidentiary boundary in school census teacher module; aggregate completion cannot substitute for a reasoned account of unequal consequence. The school head certifies the return, and the district validates unresolved identity or assignment differences.

authoritative, request, personnel, school define the evidentiary boundary in school census teacher module; aggregate completion cannot substitute for a reasoned account of unequal consequence. It collects school-level facts needed for reconciliation. Pre-populated fields can reduce burden, but schools must be able to report a factual discrepancy without altering the authoritative personnel record directly.

cycle, subject, dates, replaced change the practical judgement in timetable module because the responsible body must identify distribution, timing and remedy. The cycle start and end dates permit term changes. Cancelled or replaced periods are held in a delivery record, not by editing the approved timetable after the event.

classes, conflict, exception, teacher change the practical judgement in timetable module because the responsible body must identify distribution, timing and remedy. A flagged conflict is returned to the school for correction or a documented exception.

eligibility, status, entrants, withdrawals are material to training-provider cohort module only when the record connects the stated measure to actual delivery and affected learners. Candidate linkage uses protected identifiers under lawful arrangements. Aggregate publication distinguishes provider-reported completion from recognition and employment eligibility.

sustainable, receive, includes, since are material to training-provider cohort module only when the record connects the stated measure to actual delivery and affected learners. Changes to programme duration or requirements receive an effective date.

whether, observer, fields, field define the evidentiary boundary in absence and delivery observation form; aggregate completion cannot substitute for a reasoned account of unequal consequence. It does not ask the observer to judge whether absence is lawful. Verification fields are completed later by authorised personnel.

outcomes, sampling, support, aggregate require the absence and delivery observation form analysis to distinguish authority, observed condition and educational effect. They remain in the field dataset and are handled under the sampling protocol. Free-text notes support resolution but are not substituted for controlled categories in aggregate statistics.

code, producing, checksum, error change the practical judgement in data transfer and validation because the responsible body must identify distribution, timing and remedy. Each submission has reporting period, producing authority, creation date, record count and checksum. Rejected records return a specific error; valid records are not discarded because other records fail.

validity, totals, validation, checks are material to data transfer and validation only when the record connects the stated measure to actual delivery and affected learners. Entry checks format and code validity. Consolidation checks cross-source identity and timing. Pre-publication checks totals, revisions, tables and disclosure risk.

distinguish, release, according, analytical are material to retention and confidentiality only when the record connects the stated measure to actual delivery and affected learners. Public analytical files remove direct identifiers and limit combinations that permit re-identification. Access roles distinguish payroll operation, personnel administration, statistical analysis and public release.

correction, follows, personnel, aggregate change the practical judgement in retention and confidentiality because the responsible body must identify distribution, timing and remedy. When correction materially changes an aggregate, the statistical release follows the revision policy.

indicator, fixed, statistic, examples define the evidentiary boundary in measurement risk; aggregate completion cannot substitute for a reasoned account of unequal consequence. Examples include headcount used as labour input, payroll used as presence, trained status used as effectiveness and ratio used as class size. The control is conceptual before it is technical: the indicator name, unit and permissible claim are fixed before collection.

coded, measures, vacancy, posts are material to administrative gaming only when the record connects the stated measure to actual delivery and affected learners. Posts may be reclassified, pupils shifted between dates, teachers temporarily reassigned for the census or unknown qualifications coded as compliant. Independent reconciliation and multiple measures reduce this risk.

indicators, against, share, contact require the administrative gaming analysis to distinguish authority, observed condition and educational effect. A drive to lower vacancies is checked against arrival and retention; a drive to increase trained share is checked against unknown status and subject match; a drive to increase contact time is checked against preparation and lawful workload.

before, teachers, ratios, contextual are material to perverse redistribution only when the record connects the stated measure to actual delivery and affected learners. The safeguard is a service-based entitlement with minimums and contextual evidence. Redistribution is tested for access, curriculum and continuity before implementation.

reputation, individuals, before, reporting are material to workforce rights and due procedure only when the record connects the stated measure to actual delivery and affected learners. Statistical anomalies are not disciplinary findings. Individuals receive applicable notice, evidence and review before adverse employment action. Aggregate reporting does not name teachers in absence or qualification tables.

recommendation, assessment, rules, recommendation require the workforce rights and due procedure analysis to distinguish authority, observed condition and educational effect. The 1966 Recommendation provides a basis for participation and objective assessment within the education service.[REF-02]

sensitive, limited, routine, absence define the evidentiary boundary in privacy and security; aggregate completion cannot substitute for a reasoned account of unequal consequence. Collection is limited to necessary fields. Health status is not gathered for routine workforce planning when aggregate mortality or absence evidence is sufficient.

rounding, security, during, duties require the privacy and security analysis to distinguish authority, observed condition and educational effect. Public tables use suppression, aggregation or controlled rounding where small cells could identify a person. Security-sensitive school locations can be aggregated during conflict.

error, separate, missing, assignments require the statistical uncertainty analysis to distinguish authority, observed condition and educational effect. Sampling error, model range, classification uncertainty and coverage gap are separate limitations. A narrow model interval does not compensate for missing private-school teachers or unknown assignments.

ratios, establish, credential, matrix require the policy overclaim analysis to distinguish authority, observed condition and educational effect. A credential share does not establish classroom practice. The safeguard is a claim-evidence matrix reviewed before release.

underserved, dated, against, proposed change the practical judgement in proportionality test because the responsible body must identify distribution, timing and remedy. Is the proposed action connected to its cause? Is a less disruptive effective action available? Are impacts on underserved pupils and teachers assessed? Is the action reviewable against a dated result?

directly, transfer, weak, delaying define the evidentiary boundary in proportionality test; aggregate completion cannot substitute for a reasoned account of unequal consequence. It also prevents data limitations from indefinitely delaying a necessary response where the service failure is directly observed.

estimates, appears, residual, pass are material to disclosure of unresolved risk only when the record connects the stated measure to actual delivery and affected learners. A publication can pass statistical preparation while noting that a material share of credentials remains unverified or that presence estimates exclude inaccessible areas. The limitation appears with the affected finding and in the technical register.

feasible, twelve, payroll, assignment change the practical judgement in opening assessment because the responsible body must identify distribution, timing and remedy. Each domain is classified by evidence available, decision prevented and feasible next improvement.

payroll, domains, different, single define the evidentiary boundary in opening assessment; aggregate completion cannot substitute for a reasoned account of unequal consequence. A single score would allow strength in payroll to offset absence of assignment data. The domains remain visible because each can block a different decision.

await, status, first, date are material to first operational cycle only when the record connects the stated measure to actual delivery and affected learners. It need not await a complete historical series. Unknown status and unresolved exceptions are included as results.

funded, consequential, given, active define the evidentiary boundary in first operational cycle; aggregate completion cannot substitute for a reasoned account of unequal consequence. Less consequential descriptive fields can follow.

ranges, narrows, pupil, sensitivity change the practical judgement in projection cycle because the responsible body must identify distribution, timing and remedy. The first projection may use broad attrition or training-yield ranges if detailed cohorts are unavailable. The range narrows only as evidence improves.

total, reconciled, teacher, years change the practical judgement in projection cycle because the responsible body must identify distribution, timing and remedy. Separate projections that use different teacher counts, salary bases or school years are not combined in a final total.

scheduled, entitlements, classifies, surplus are material to deployment cycle only when the record connects the stated measure to actual delivery and affected learners. The authority then classifies shortage, justified minimum, feasible surplus and mismatch. Movement, recruitment and support actions are scheduled with effective dates and responsibilities.

Implementation monitoring records appointment, arrival, timetable assignment and retention. A transfer order or signed contract is an intermediate event, not the service result.

data, remains, contains, core define the evidentiary boundary in statistical release cycle; aggregate completion cannot substitute for a reasoned account of unequal consequence. Tables are generated from the same controlled data used for the narrative. A correction protocol remains open after publication.

personnel, timetabling, training, statistical define the evidentiary boundary in institutional capability; aggregate completion cannot substitute for a reasoned account of unequal consequence. Training is directed to actual functions. A central statistical course does not equip district officers to resolve transfer and assignment transactions unless those tasks are included.

Documentation is an operational asset. Definitions, code lists, validation rules and recurring procedures are maintained so that the system does not depend on one individual.

post, reporting, projection, implementation are material to capability indicators only when the record connects the stated measure to actual delivery and affected learners. Relevant indicators include the share of active persons with valid assignment, the proportion of post and payroll exceptions resolved within the period, reporting timeliness, credential verification coverage, projection residuals and publication correction time.

teacher, accompanied, indicators, performance change the practical judgement in capability indicators because the responsible body must identify distribution, timing and remedy. They are owned by the responsible office and accompanied by the resources needed to improve them.

school, governed, events, fixed define the evidentiary boundary in maintenance; aggregate completion cannot substitute for a reasoned account of unequal consequence. Annual clean-up cannot substitute for timely transaction control. Code changes, school openings and policy revisions enter through governed procedures.

measures, target, longer, series define the evidentiary boundary in maintenance; aggregate completion cannot substitute for a reasoned account of unequal consequence. Measures that no longer serve a decision are revised or retired with a documented series break.

responsible, establish, largest, limited define the evidentiary boundary in final implementation principle; aggregate completion cannot substitute for a reasoned account of unequal consequence. It is to produce timely, limited and trustworthy evidence that connects public expenditure to instruction. The implementation programme is successful when vacancies, deployment gaps and lost time can be identified early enough for a responsible authority to act and when the public account remains accurate about what the data do not establish.

element, separated, unit, source require the metadata as part of the result analysis to distinguish authority, observed condition and educational effect. Name, purpose, population, unit, numerator, denominator, reference period, source, collection method, coverage, calculation, revision and limitation are held in one controlled record. A change in any defining element receives a new version.

interpretation, meaning, record, prevent define the evidentiary boundary in metadata as part of the result; aggregate completion cannot substitute for a reasoned account of unequal consequence. Detail that affects only processing can remain internal; detail that affects meaning cannot.

headcount, includes, teachers, defines change the practical judgement in teacher headcount metadata because the responsible body must identify distribution, timing and remedy. It defines the reference date and the rule for active employment.

defined, reconciled, unique, described are material to teacher headcount metadata only when the record connects the stated measure to actual delivery and affected learners. If cross-sector identity cannot be reconciled, sector totals are published without claiming that their sum is a unique-person total. A teacher headcount is not described as available or classroom teaching unless assignment and function are part of the measure.

instructional, defines, used, posts require the full-time-equivalent metadata analysis to distinguish authority, observed condition and educational effect. Contracted FTE, assigned teaching FTE and instructional FTE have separate indicator codes.

whether, differ, rule, workloads define the evidentiary boundary in full-time-equivalent metadata; aggregate completion cannot substitute for a reasoned account of unequal consequence. One universal divisor is not applied to incompatible workloads. Comparisons identify whether pupil FTE is also used.

actual, development, pupils, denominator are material to pupil–teacher ratio metadata only when the record connects the stated measure to actual delivery and affected learners. The record specifies sector coverage, assignment treatment and whether teachers are counted regardless of actual teaching assignment, as in the definition reported in *World Development Indicators 2004*.[REF-05]

does, affected, time, 1997 are material to pupil–teacher ratio metadata only when the record connects the stated measure to actual delivery and affected learners. If a time series crosses the ISCED 1976 to ISCED 1997 transition, the break is disclosed.[REF-05] [REF-10]

share, precisely, organised, numerator define the evidentiary boundary in trained-teacher share metadata; aggregate completion cannot substitute for a reasoned account of unequal consequence. The numerator includes only teachers verified as meeting it. The denominator for the percentage and the full-stock unknown share are both reported.

include, self, international, content are material to trained-teacher share metadata only when the record connects the stated measure to actual delivery and affected learners. This preserves the caution set out in the 2004 international source.[REF-05]

denominator, recruitment, frozen, bands define the evidentiary boundary in vacancy metadata; aggregate completion cannot substitute for a reasoned account of unequal consequence. Filled-but-unoccupied, temporarily covered and frozen posts are distinct statuses. The reference date and duration bands are included.

interpretation, teacher, comparison, interpretation change the practical judgement in vacancy metadata because the responsible body must identify distribution, timing and remedy. Comparison with calculated service entitlement provides the planning interpretation.

treatment, late, actual, boundary define the evidentiary boundary in attrition metadata; aggregate completion cannot substitute for a reasoned account of unequal consequence. The metadata lists included reasons, treatment of transfers, denominator, time at risk and late-recorded events. Retirement eligibility and actual retirement are separate measures.

subject, even, labelled, denominator define the evidentiary boundary in attrition metadata; aggregate completion cannot substitute for a reasoned account of unequal consequence. Rates by subject or region identify movement out of that group even when the person remains in the national system; these are labelled group exits, not national attrition.

target, observation, visits, closure define the evidentiary boundary in presence metadata; aggregate completion cannot substitute for a reasoned account of unequal consequence. It reports uncertainty and non-response.

rule, absence, included, rule are material to presence metadata only when the record connects the stated measure to actual delivery and affected learners. “Unauthorised absence” is reserved for verified cases under the governing rule.

separate, more, contact, availability change the practical judgement in instructional-capacity metadata because the responsible body must identify distribution, timing and remedy. It explains whether capacity is estimated from separate factors or directly from period records. The same loss is not applied more than once.

The limitation states that delivered time is not evidence of pedagogical quality or learning. Subject-matched capacity has an additional dated match rule.

material, before, current, expected are material to metadata governance only when the record connects the stated measure to actual delivery and affected learners. A change request states why the current measure no longer serves its purpose, expected series effect and recoding feasibility. Statistical and policy users are informed before release where a break is material.

appointment, begins, field, already define the evidentiary boundary in whether to expand preparation intake; aggregate completion cannot substitute for a reasoned account of unequal consequence. It subtracts eligible candidates already in the pathway, credible re-entrants and feasible redistribution. It then applies completion and appointment yields to determine admissions.

permanent, institutions, demand, instructors require the whether to expand preparation intake analysis to distinguish authority, observed condition and educational effect. The decision states whether additional intake is permanent or temporary. A temporary bulge has an exit strategy so that institutions and candidates are not left with unsupported capacity after demand falls.

curriculum, assignments, funding, planning define the evidentiary boundary in whether to create new posts; aggregate completion cannot substitute for a reasoned account of unequal consequence. Evidence includes projected pupils, curriculum, class or period formation, existing assignments, feasible redistribution and duration of need. Funding covers salary and associated costs over the planning horizon.

deployment, teacher, post, facility are material to whether to create new posts only when the record connects the stated measure to actual delivery and affected learners. If the school does not open, the appointment and deployment plan is revised rather than leaving a teacher notionally assigned to a non-operating location.

recipient, excess, procedure, consultation require the whether to redeploy staff analysis to distinguish authority, observed condition and educational effect. It estimates both donor-school and recipient-school effects.

complete, receiving, movement, counting require the whether to redeploy staff analysis to distinguish authority, observed condition and educational effect. Non-arrival, appeal or delayed movement remains visible. The staffing account avoids counting the same FTE at both schools during the transition.

identifies, general, binding, turnover require the whether to introduce a hardship measure analysis to distinguish authority, observed condition and educational effect. The decision identifies which constraint the measure is intended to change. A general allowance may be poorly targeted if housing or delayed pay is the binding problem.

without, evaluation, period, receipt define the evidentiary boundary in whether to introduce a hardship measure; aggregate completion cannot substitute for a reasoned account of unequal consequence. Receipt and timeliness are measured. Retention without presence or service continuity is insufficient evidence of success.

record, selection, transition, temporary require the whether to use temporary appointments analysis to distinguish authority, observed condition and educational effect. It considers whether the temporary route draws candidates away from full preparation.

plan, population, conditions, without are material to whether to use temporary appointments only when the record connects the stated measure to actual delivery and affected learners.

requirements, staffing, curriculum, assessment define the evidentiary boundary in whether to change teacher contact hours; aggregate completion cannot substitute for a reasoned account of unequal consequence. It estimates staffing and service effects, not only salary savings.

work, support, record, time define the evidentiary boundary in whether to change teacher contact hours; aggregate completion cannot substitute for a reasoned account of unequal consequence. Reducing contact time may support quality but requires additional staff. The policy record states the evidence and trade-off.

makes, maps, safety, school define the evidentiary boundary in whether to consolidate small schools; aggregate completion cannot substitute for a reasoned account of unequal consequence. Staffing efficiency is one component. A consolidation that makes attendance impracticable does not improve educational access.

teaching, included, responsibility, grade change the practical judgement in whether to consolidate small schools because the responsible body must identify distribution, timing and remedy. Community evidence is included, but the decision remains subject to the child's educational opportunity and public responsibility.

exceptional, justified, foreseeable, suitable require the whether to publish school-level results analysis to distinguish authority, observed condition and educational effect. A school-level ratio may be suitable; individual absence or qualification details ordinarily are not. Small cells and exceptional circumstances require protection.

The release provides correction and contextual notes. School publication does not substitute for the authority's duty to correct a known shortage.

record, records, function, assessment require the decision integrity analysis to distinguish authority, observed condition and educational effect. It records departure from the evidence with the authority and reason. This protects the statistical function from being recast after the event and permits public assessment of whether implementation matched the stated basis.

frames, enabling, teacher, conditions change the practical judgement in education for all quality evidence because the responsible body must identify distribution, timing and remedy. It frames quality through learner characteristics, context, enabling inputs, teaching and learning, and outcomes. Its teacher evidence supports the proposition that numbers, preparation, conditions and instructional procedure are connected, but it does not create a single teacher-quality index.[REF-03]

later, bound, enabling, learning change the practical judgement in education for all quality evidence because the responsible body must identify distribution, timing and remedy. Workforce statistics describe enabling capacity and part of the procedure; they do not replace learning evidence. Where the EFA report presents country or regional observations, later revisions are not imported.

statistical, here, country, through are material to global education digest 2004 only when the record connects the stated measure to actual delivery and affected learners. Its role here is definition and coverage rather than creation of a new country ranking. National education structures are mapped through ISCED 1997, with national detail retained.[REF-04] [REF-10]

therefore, school, year, refers require the global education digest 2004 analysis to distinguish authority, observed condition and educational effect. Reference years are taken from the table and note. A report using these data in March 2005 therefore describes the latest reported observation, not the current school condition without qualification.

absence, preliminary, staff, unexcused require the world development report 2004 analysis to distinguish authority, observed condition and educational effect. The source defines the rate as the percentage of staff supposed to be present but not present, including excused and unexcused absence.[REF-06]

absence, extend, individual, average define the evidentiary boundary in world development report 2004; aggregate completion cannot substitute for a reasoned account of unequal consequence. It does not extend the figures to countries not observed, to later years or to individual misconduct. The India figure is identified as an average for 14 states, not a national census.

providers, financed, adopt, wider change the practical judgement in world development report 2004 because the responsible body must identify distribution, timing and remedy. This report uses the narrower measurement implication: financed employment must be connected to service received. It does not adopt every institutional prescription for every country.

parameters, reform, model, relatively define the evidentiary boundary in achieving universal primary education by 2015; aggregate completion cannot substitute for a reasoned account of unequal consequence. It reports wide ranges in service-delivery parameters and constructs simulations around country reform paths. Its 40:1 pupil–teacher ratio is a model parameter associated with the observed average of a relatively higher-completion group, not a universal standard.[REF-07]

inputs, costs, conditions, uses define the evidentiary boundary in achieving universal primary education by 2015; aggregate completion cannot substitute for a reasoned account of unequal consequence. Selective citation of 40:1 without those conditions would misrepresent the source. The present study uses the value only to demonstrate scenario practice and benchmark limits.

acknowledges, school, planners, timetable require the achieving universal primary education by 2015 analysis to distinguish authority, observed condition and educational effect. It does not supply school-level entitlement rules. National planners must therefore move from aggregate scenario to school and timetable calculation.

teacher, equivalents, reports, salaries define the evidentiary boundary in education at a glance 2004; aggregate completion cannot substitute for a reasoned account of unequal consequence. It reports instruction time, teaching time, working-time organisation, salaries and decision structures for participating systems.[REF-08]

institutional, values, harmonisation, class are material to education at a glance 2004 only when the record connects the stated measure to actual delivery and affected learners. Values are not combined into one global distribution without harmonisation. The conceptual distinction between ratio, class size and time is transferable; the numerical results are not assumed to apply outside the reported population.

status, normative, staffing, professional require the international recommendations and rights instruments analysis to distinguish authority, observed condition and educational effect. It guides the normative context but does not prescribe a global staffing ratio.[REF-02]

informs, purpose, indicator, without define the evidentiary boundary in international recommendations and rights instruments; aggregate completion cannot substitute for a reasoned account of unequal consequence. It does not convert every workforce indicator into a direct legal compliance test without analysis of the applicable obligation and facts.[REF-12]

development, strategies, workforce, provides require the united nations millennium project analysis to distinguish authority, observed condition and educational effect. Its use in this report is to support integrated and sequenced planning. It is not used as evidence for workforce outcomes that had not yet occurred by the cut-off.[REF-09]

scope, based, revise, values define the evidentiary boundary in evidence hierarchy; aggregate completion cannot substitute for a reasoned account of unequal consequence. Analytical propositions are attributed to their study and retain scope. ICEQC calculations are labelled as illustrations or calculations based on cited data. No later source is used to revise the contemporaneous position.

workforce, funding, position, authorisation change the practical judgement in authorised post because the responsible body must identify distribution, timing and remedy. Authorisation does not establish that funding is available, a person is appointed or service is delivered.

An authorised position with budget provision for the stated period. A funded post may be vacant, frozen, temporarily covered or filled.

A post to which an appointment is active. The term does not establish that the appointee has reported, is assigned to a school, is present or is teaching.

The number of unique persons meeting the stated teacher and active-status definition at the reference date. Headcount gives equal weight to full-time and part-time persons.

The sum of teacher workloads expressed relative to the nationally defined full-time workload. Contracted, assigned and instructional FTE are distinct.

Personnel directly involved in instruction under the applicable statistical definition. The treatment of principals, specialists and mixed functions must be stated.

term, preparation, used, organised require the trained teacher analysis to distinguish authority, observed condition and educational effect. The term is nationally defined and does not establish common preparation across countries.[REF-05]

separately, meeting, rule, separately define the evidentiary boundary in professionally qualified teacher; aggregate completion cannot substitute for a reasoned account of unequal consequence. This may coincide with trained status but is retained separately where national law or data distinguish them.

The relationship between recognised preparation and assigned curriculum under a dated national match rule. It is calculated by period where assignments are mixed.

Pupils divided by teachers within a stated level, sector, period and unit. It is a resource ratio and is not average class size.

Pupils divided by teachers meeting the stated national preparation requirement. It combines resource quantity and nationally defined status but does not measure teaching quality.

defined, different, more, group are material to class size only when the record connects the stated measure to actual delivery and affected learners. A pupil can belong to different groups by subject; a teacher can serve more than one class.

groups, teacher, total, groups require the teacher contact time analysis to distinguish authority, observed condition and educational effect. It is part of total working time and differs from pupil instruction time where schedules or groups vary.

time, calendar, learning, annual change the practical judgement in instructional full-time equivalent because the responsible body must identify distribution, timing and remedy. It measures delivered time capacity, not pedagogy or learning.

open, specified, filled, definition define the evidentiary boundary in vacancy; aggregate completion cannot substitute for a reasoned account of unequal consequence. The vacancy definition states whether posts temporarily covered or not open for recruitment are included.

feasible, deployment, teacher, feasible define the evidentiary boundary in teacher shortage; aggregate completion cannot substitute for a reasoned account of unequal consequence. It depends on entitlement, capability, deployment and time, not vacancies alone.

Movement of a person into the defined teacher workforce during the period. First entry, re-entry and transfer in are separately classified.

period, other, treated, workforce define the evidentiary boundary in attrition; aggregate completion cannot substitute for a reasoned account of unequal consequence. Retirement, resignation, death, dismissal and other reasons are separated; internal transfers are treated according to the boundary.

Movement into and out of a school, district or group. It can be high when national attrition is low because internal transfers contribute.

schools, deployment, effective, teacher change the practical judgement in deployment because the responsible body must identify distribution, timing and remedy. A deployment order is complete for service measurement only after effective arrival and timetable assignment.

The observed or validly recorded condition of an expected teacher being at the required location and time. It does not by itself show that instruction occurred.

The condition of an expected teacher not observed present under a stated visit design. It can include authorised and unauthorised reasons until verification.

Absence determined under the applicable rule to lack authorisation after verification and due procedure. It is not inferred solely from an unannounced visit.

The portion of intended calendar time during which the school is operating and available to pupils. It is distinct from teacher presence and pupil attendance.

A scheduled instructional period that occurred under the stated delivery rule. Replacement, combined-class and shortened-period arrangements are separately coded.

condition, instruction, deliver, learning change the practical judgement in instructional capacity because the responsible body must identify distribution, timing and remedy. It is an enabling condition and not a learning outcome.

Recruitment or return required to offset expected exits and workload reduction. It exists even where enrolment and target workforce stock are stable.

Additional capacity required because pupil numbers, programmes, curriculum, access conditions or staffing policy expand.

Growth demand plus replacement demand, less credible re-entry and transfers in, with the same boundary and period.

exceeds, entrant, admissions, year are material to training yield only when the record connects the stated measure to actual delivery and affected learners. Annual completions divided by annual admissions is not a cohort yield when programme duration exceeds one year.

Eligible selected candidates who accept appointment and report for duty divided by the relevant eligible candidate population. The precise stage used as denominator is stated.

The teacher FTE calculated under the approved staffing rule for a school or programme. It is distinct from inherited authorised posts and is subject to review of the rule itself.

protection, ratio, avoidable, capable are material to minimum viable staffing only when the record connects the stated measure to actual delivery and affected learners. It can produce a low ratio in small schools without implying avoidable surplus.

unresolved, recruitment, closing, events require the reconciliation residual analysis to distinguish authority, observed condition and educational effect. It indicates unresolved data or boundary change and is not labelled recruitment or attrition.

A discontinuity caused by definition, classification, coverage, source or method change. It is distinguished from an actual change in workforce or service.

A reference value used to test implications under stated evidence and context. It is not automatically a standard, target or causal threshold.

calculation, financial, conditional, workforce are material to scenario only when the record connects the stated measure to actual delivery and affected learners. It is not a prediction independent of those assumptions.

The population, sector, geography and records represented in an indicator. Coverage gaps remain explicit and can differ across numerator and denominator.

A case for which the required evidence is unavailable or unresolved. Unknown is neither compliant nor non-compliant and remains visible in denominators and limitations.

A change to a published statistic resulting from corrected data, updated source or method. Revision date, reason and series effect are disclosed.

visiting, school, work, half are material to headcount and fte reconciliation only when the record connects the stated measure to actual delivery and affected learners. Twelve work full time in classroom teaching. Two work half time. One principal teaches 40 per cent of the full-time classroom load. One full-time teacher is on long authorised leave with a separately appointed replacement. One person has transferred but remains on the school list, and one visiting teacher is counted both by this school and the home school.

retaining, workload, leave, measures change the practical judgement in headcount and fte reconciliation because the responsible body must identify distribution, timing and remedy. After removing the transferred duplicate, retaining unique persons, allocating the visitor by workload and avoiding double count between leave holder and replacement, the employment, assignment and instructional measures differ. The exact result depends on the applicable treatment of leave and the visiting fraction; the calculation record must show those choices.

headcount, reconciliation, lesson, school require the headcount and fte reconciliation analysis to distinguish authority, observed condition and educational effect. A school may have several part-time assignments from staff based elsewhere, increasing assignment headcount while producing a modest FTE. The purpose of reconciliation is to select the unit that matches the question.

weights, three, school, approximately are material to ratio calculation at national and school levels only when the record connects the stated measure to actual delivery and affected learners. Their school ratios are 20:1, 32:1 and 40:1. The unweighted mean school ratio is approximately 30. 7:1. The national aggregate ratio is 1,000 pupils divided by 27 FTE, or approximately 37. 0:1. The results differ because the aggregate weights schools by pupils and teachers through their totals.

resources, school, table, neither define the evidentiary boundary in ratio calculation at national and school levels; aggregate completion cannot substitute for a reasoned account of unequal consequence. The aggregate answers how total pupils relate to total resources. The mean describes the average of three school ratios, giving the 40-pupil school the same influence as the 800-pupil school. A public table must name the statistic and preferably show the distribution.

permits, classes, gives, national define the evidentiary boundary in class formation and rounding; aggregate completion cannot substitute for a reasoned account of unequal consequence. Each school requires two classes, for a total of eight. Aggregating first gives 164 pupils divided by 40, or 4. 1, which rounds upward to five. National-first calculation would understate the requirement by three classes because the classes cannot be pooled across schools.

organisational, mathematical, approved, schools require the class formation and rounding analysis to distinguish authority, observed condition and educational effect. It is not a mathematical correction to the class-size rule.

require, matched, fractional, lower define the evidentiary boundary in subject-period demand; aggregate completion cannot substitute for a reasoned account of unequal consequence. A full-time mathematics teacher has an 18-period contact load. The arithmetic requirement is 2. 78 FTE. Because timetables require actual people and periods, three appropriately matched full-time teachers may be necessary unless a lawful fractional appointment or cross-school assignment is feasible.

employs, half, headcount, even change the practical judgement in subject-period demand because the responsible body must identify distribution, timing and remedy. 5 FTE, not a headcount of three. The uncovered periods remain visible even if overall school teacher headcount exceeds entitlement.

hundred, preparation, trained, divided are material to trained share with unknown records only when the record connects the stated measure to actual delivery and affected learners. Seven hundred and twenty are verified as meeting the national preparation rule, 80 are verified not to meet it, and 200 have unresolved records. The trained share among known cases is 720 divided by 800, or 90 per cent. Verified trained FTE represent 72 per cent of the full stock, and the unknown share is 20 per cent.

unknown, verification, publishing, apply are material to trained share with unknown records only when the record connects the stated measure to actual delivery and affected learners. The proper presentation gives the known-case percentage, verified full-stock proportion and unknown share together. Unknown cases are then prioritised for verification rather than converted to either category.

districts, internal, opens, resign change the practical judgement in attrition and turnover because the responsible body must identify distribution, timing and remedy. During the year, 300 retire, 100 resign, 50 die, 30 are dismissed and 20 leave for other recorded reasons. Five hundred teachers transfer between districts. National attrition is 500 exits divided by 10,000, or 5 per cent. The 500 internal transfers do not change national stock.

attrition, transfer, locally, districts are material to attrition and turnover only when the record connects the stated measure to actual delivery and affected learners. If all movements were added to national attrition, replacement demand would be overstated because each transfer in is also an available teacher elsewhere in the national system. If transfers were ignored locally, staffing instability would be understated.

preparation, cohort, completers, duty are material to training pathway only when the record connects the stated measure to actual delivery and affected learners. If 1,360 of those completers apply and are eligible, 1,200 accept appointment and 1,140 report for duty, the report-to-duty yield from recognised completers is 71. 25 per cent.

timing, secure, more, stability define the evidentiary boundary in training pathway; aggregate completion cannot substitute for a reasoned account of unequal consequence. The correct planning response may also include improving completion, appointment timing or acceptance rather than expanding admissions alone.

absent, verification, duty, survey require the presence estimate and reason composition analysis to distinguish authority, observed condition and educational effect. The observed absence rate is 18 per cent. Verification classifies 180 absent opportunities as authorised leave, 90 as official duty or training, 120 as unauthorised and 60 as unresolved.

absence, among, unresolved, estimating define the evidentiary boundary in presence estimate and reason composition; aggregate completion cannot substitute for a reasoned account of unequal consequence. The unauthorised share among all expected opportunities is 4. 8 per cent under the verified classification; the unresolved share is 2. 4 per cent. It would be incorrect to describe all 18 per cent as unauthorised, and it would also be incorrect to exclude authorised absence when estimating immediate replacement need.

The sampling interval accompanies each estimate. The weighted counts presented here are illustrative and do not carry a calculated interval because no sample design is specified.

delivered, million, cancel, leaves require the instructional-time account analysis to distinguish authority, observed condition and educational effect. School closures cancel 400,000. Among the 9. 6 million periods in open schools, teacher unavailability leaves 700,000 uncovered; replacement staff deliver 300,000 of those. Of the remaining scheduled periods with an available teacher, 100,000 are not delivered for other recorded reasons.

replacement, period, conditional, answer require the instructional-time account analysis to distinguish authority, observed condition and educational effect. 1 million if the replacement periods are included and each loss is counted once. The delivered-period rate is 91 per cent of intended periods, while the rate conditional on schools being open is approximately 94. 8 per cent. The two denominators answer different questions and are both labelled.

cent, calculation, need, filled change the practical judgement in vacancy and entitlement because the responsible body must identify distribution, timing and remedy. Fifty funded posts are vacant, giving a funded-vacancy rate of about 4. 8 per cent. A current school-based demand calculation, however, indicates an entitlement of 1,080 FTE. Relative to current service need, the filled gap is 80 FTE, not 50.

required, establishment, entitlement, funded define the evidentiary boundary in vacancy and entitlement; aggregate completion cannot substitute for a reasoned account of unequal consequence. Conversely, if entitlement were 970 FTE, a vacancy rate would still exist within the funded establishment while the district held an apparent aggregate surplus relative to the current rule. Both comparisons are required before action.

between, large, distribution, organisational define the evidentiary boundary in deployment dispersion; aggregate completion cannot substitute for a reasoned account of unequal consequence. In one, most schools lie between 32:1 and 38:1. In the other, remote schools operate at 15:1 while large schools reach 60:1. The first has a relatively concentrated distribution; the second has marked dispersion and likely organisational constraints.

separated, data, testing, merely define the evidentiary boundary in deployment dispersion; aggregate completion cannot substitute for a reasoned account of unequal consequence. The relevant finding is not merely that the second region is unequal. It is that pupils encounter very different staffing conditions and the reasons must be separated into justified minimum provision, avoidable concentration and data error.

currency, cent, before, grows define the evidentiary boundary in salary scenario; aggregate completion cannot substitute for a reasoned account of unequal consequence. Annual employment cost is 36 million units before preparation, substitution and administration. If the workforce grows by 5 per cent and the salary scale rises by 4 per cent, the next-year employment cost is not 36 million plus 9 per cent when grade composition, part-year recruitment and allowances change; a grade-level calculation is required.

The simple approximation—39.312 million—can serve as a check. Material deviation from the detailed calculation is explained by timing or composition rather than hidden in a total.

enrolment, appointment, much, pathway change the practical judgement in scenario sensitivity because the responsible body must identify distribution, timing and remedy. If projected enrolment is 3 per cent higher, attrition rises from 5 to 7 per cent, and appointment yield falls from 85 to 75 per cent, candidate requirement can rise by much more than 3 per cent because growth, replacement and pathway conversion compound.

plausible, regardless, jointly, combined require the scenario sensitivity analysis to distinguish authority, observed condition and educational effect. Reporting only one-factor changes can understate combined implementation pressure. The joint case must remain plausible; it is not constructed by combining every extreme regardless of coherence.

boundary, time, projection, verb define the evidentiary boundary in interpretation tests; aggregate completion cannot substitute for a reasoned account of unequal consequence. The **unit test** asks whether the noun in the sentence matches the statistical unit. The **boundary test** asks whether level, sector and geography match. The **time test** asks whether the date supports a current, trend or projection statement. The **claim test** asks whether the measure can support the verb and conclusion.

quality, correction, footnote, value change the practical judgement in interpretation tests because the responsible body must identify distribution, timing and remedy. Correction is made in the sentence, not deferred to a distant footnote.

quantities, boundaries, region, assumptions define the evidentiary boundary in closing note on worked examples; aggregate completion cannot substitute for a reasoned account of unequal consequence. They demonstrate calculation boundaries and failure modes; they do not describe a country, region or school. Their value lies in making assumptions inspectable. A national application replaces every illustrative value with verified evidence and retains the same controls.

financing, does, statistical, used are material to purpose only when the record connects the stated measure to actual delivery and affected learners. It asks whether the proposed stock, recruitment, deployment and financing decisions can produce the stated instructional service. It does not assess individual teachers and does not convert statistical exceptions into employment findings.

instructional, balance, review, pupil require the service boundary analysis to distinguish authority, observed condition and educational effect. Teacher headcount, FTE, posts and instructional periods are aligned to that boundary. A national balance is not accepted as evidence of district or subject sufficiency.

before, personnel, unresolved, qualifications define the evidentiary boundary in base-year integrity; aggregate completion cannot substitute for a reasoned account of unequal consequence. Unresolved duplicates, unassigned persons and unknown qualifications remain visible. A material residual prevents precise projection and is carried as a sensitivity or corrected before decision.

periods, included, arithmetic, pupil change the practical judgement in demand logic because the responsible body must identify distribution, timing and remedy. Upward rounding, minimum schools, subject periods, contact time and travel constraints are included. The review rejects national-first arithmetic that cannot produce a feasible school timetable.

appoint, supplies, safeguards, replacement change the practical judgement in supply logic because the responsible body must identify distribution, timing and remedy. Training admissions, recognised completion, appointment acceptance and report-to-duty yields are not merged. The plan cannot appoint more suitable candidates than the pathway supplies without identifying an interim route and its safeguards.

surplus, subject, movement, person change the practical judgement in deployment feasibility because the responsible body must identify distribution, timing and remedy. Transfers have realistic dates and conditions. A person is not counted at the receiving school until assignment becomes effective and service is confirmed.

availability, counted, design, intended define the evidentiary boundary in time and availability; aggregate completion cannot substitute for a reasoned account of unequal consequence. Replacement provision is not counted twice. Presence evidence retains its observation design and reason limitations.

capacity, complementary, crowding, after change the practical judgement in financial sustainability because the responsible body must identify distribution, timing and remedy. Complementary materials and management are protected from unexamined salary crowding. Recurrent obligation remains visible after transitional finance ends.

subject, turnover, teacher, efficiency require the equity and professional safeguards analysis to distinguish authority, observed condition and educational effect. It also examines teacher conditions, consultation, privacy and due procedure. An efficiency measure that removes minimum service fails the review.

reopens, competent, plan, assumptions define the evidentiary boundary in decision disposition; aggregate completion cannot substitute for a reasoned account of unequal consequence. Approval identifies critical assumptions and the date on which actual recruitment, deployment, cost and instructional coverage will be compared with the plan. A material assumption failure reopens the relevant decision rather than being concealed in an aggregate variance.

more, informative, payment, every change the practical judgement in warning as a decision function because the responsible body must identify distribution, timing and remedy. It is an ordered body of evidence showing that the probability, expected scale or likely duration of an interruption has changed enough to justify verification or preventive action. The distinction matters because education authorities operate under uncertainty. Retirement eligibility is known more precisely than actual retirement; an application for transfer is more informative than a stated preference; a delayed salary payment may precede departure without causing every affected teacher to leave. Each signal therefore requires a defined decision use, a review interval and a named authority able to respond.

insecurity, burden, salary, unfilled change the practical judgement in warning as a decision function because the responsible body must identify distribution, timing and remedy. Exposure indicators include age structure, remoteness, housing scarcity, insecurity, high living costs, disease burden and dependence on a narrow preparation pathway. Pressure indicators include salary arrears, repeated excess workload, unfilled leadership posts, deteriorating housing, exceptional absence and unsuccessful recruitment rounds. Intention indicators include applications for transfer, non-renewal notices, retirement inquiries and withdrawal after appointment. Event indicators include resignation, retirement, death, dismissal, transfer, failure to report and a funded post remaining unfilled after its recruitment window. Authorities should not collapse these stages into one attrition rate.

intake, growing, falling, commonly change the practical judgement in warning as a decision function because the responsible body must identify distribution, timing and remedy. A rising share of teachers eligible to retire may justify preparation-intake review where pupil demand is stable or growing. It should not automatically trigger recruitment if enrolment is falling, subject requirements are changing or eligible staff commonly remain. Repeated vacancy advertisements with no qualified applicants may justify attention to pay, housing, preparation supply or appointment delay. They do not establish which response will work. The warning record should state the observed measure, its threshold or comparison, the mechanism requiring investigation, the response available and the cost of a false alarm or missed warning. This is the discipline that converts workforce statistics into service protection.[REF-13] [REF-14]

closing, during, flow, unique define the evidentiary boundary in attrition definitions and competing denominators; aggregate completion cannot substitute for a reasoned account of unequal consequence. Its numerator comprises members of that workforce who, by the end of the observation interval, are no longer active in the defined teaching service. Its denominator is normally the opening active workforce, not the closing workforce and not all persons ever appearing on the payroll during the year. Entries during the year belong in the stock-and-flow account but do not belong in the opening cohort. Where records cannot identify a unique person across years, apparent attrition may be produced by changed identifiers, delayed returns or reassignment between administrative units.

loss, reflect, maldistribution, total define the evidentiary boundary in attrition definitions and competing denominators; aggregate completion cannot substitute for a reasoned account of unequal consequence. Total service attrition records departures from the defined education workforce. Occupational attrition records departure from teaching even when the person remains employed by the ministry. School attrition records departure from a particular school and therefore includes transfers within the system. Contract attrition records non-renewal or non-return among a specified temporary cohort. These measures answer different questions. A national service may retain nearly all teachers while schools serving remote or disadvantaged communities experience repeated loss. Conversely, high school mobility may partly reflect planned promotion or correction of an earlier maldistribution.

promotion, expiry, planned, lead define the evidentiary boundary in attrition definitions and competing denominators; aggregate completion cannot substitute for a reasoned account of unequal consequence. Retirement, death, long-term incapacity, resignation for another occupation, international migration, domestic transfer, promotion to non-teaching work, dismissal, contract expiry and unknown departure should remain separate. Planned and unplanned losses impose different lead times. Preventable and unavoidable are evaluative categories requiring evidence, not codes to be assigned from assumption. Unknown status must be published because a falling unknown share can raise recorded attrition without any change in actual behaviour.

matching, work, distinguishing, measures are material to attrition definitions and competing denominators only when the record connects the stated measure to actual delivery and affected learners. Authorities should follow new appointees from acceptance through reporting, completion of the first term, completion of induction and continued service after one, three and five years where records permit. Loss before reporting points to a different institutional failure from loss after several years. Comparable reporting requires the service boundary, employment categories, treatment of leave, observation dates, matching procedure and revision policy. OECD comparative work available by the cutoff reinforces the importance of distinguishing policies for the whole profession from targeted measures for particular teachers and schools.[REF-14]

normal, published, fiscal, merely change the practical judgement in vacancy measures and hidden unmet need because the responsible body must identify distribution, timing and remedy. The authorised-post vacancy rate compares unfilled authorised full-time-equivalent posts with all authorised posts. The funded-post vacancy rate narrows the denominator to positions for which resources have been released. A recruitment vacancy may be defined still more narrowly as a funded post approved for recruitment and unfilled after the normal appointment interval. These indicators should be published together where differences are material. Otherwise a fiscal restriction can make the vacancy rate appear to improve merely because needed posts were never funded.

filled, implied, formation, recorded require the vacancy measures and hidden unmet need analysis to distinguish authority, observed condition and educational effect. It compares filled, appropriately matched instructional capacity with capacity implied by current enrolment, curriculum, class-formation and minimum-school rules. The service gap may exceed recorded vacancies when establishments have not been updated for population growth, new grades, language provision or small-school requirements. It may be smaller than authorised vacancies where enrolment has declined or duplicate posts remain. Neither result licenses automatic abolition or appointment: it triggers reconciliation of legal entitlement, educational demand and finance.

date, repeated, post, most define the evidentiary boundary in vacancy measures and hidden unmet need; aggregate completion cannot substitute for a reasoned account of unequal consequence. Authorities should distinguish posts vacant at the reference date, vacancy-days accumulated during the term, and repeated vacancy episodes affecting the same school or subject. A post filled on census day after being empty for most of the year should not be treated as uninterrupted provision. A short vacancy covered by an appropriately prepared substitute differs from one covered by merged classes, cancelled subjects or unqualified assignment. The early-warning profile therefore records opening date, recruitment steps, applicant count, qualified-applicant count, offers, acceptances, reporting, interim coverage and final disposition.

pretending, comparison, cannot, identical require the vacancy measures and hidden unmet need analysis to distinguish authority, observed condition and educational effect. Evidence may appear as classes without a teacher, systematic multi-grade combinations exceeding policy, subjects omitted from the timetable, teaching by personnel outside their preparation, or learners refused entry because staff are unavailable. These conditions should be counted as service deficits and investigated without pretending that they are internationally comparable vacancies. International comparison can align concepts and disclose differences; it cannot make different establishment laws identical.[REF-13] [REF-15]

applicant, expiry, size, dashboard are material to a minimum dashboard for national and district authorities only when the record connects the stated measure to actual delivery and affected learners. Stock measures comprise active teacher headcount, active full-time equivalent, filled instructional post equivalent, trained status under the national definition, and subject or grade match. Flow measures comprise entrants, returns, retirements, other exits, transfers in and out, and changes of teaching function. Vacancy measures comprise authorised, funded and recruitment vacancies, their duration and qualified-applicant yield. Exposure measures comprise age bands, contract expiry, temporary assignment, location, subject, school size and dependence on one-person functions.

operate, makes, reported, disadvantage define the evidentiary boundary in a minimum dashboard for national and district authorities; aggregate completion cannot substitute for a reasoned account of unequal consequence. The purpose is not to rank teachers. It is to identify concentrations of service risk. A national total can remain stable while one district loses its mathematics teachers, while beginning teachers leave particular schools, or while small schools operate without a headteacher. Distributional publication makes those differences visible.

subject, none, review, variation require the a minimum dashboard for national and district authorities analysis to distinguish authority, observed condition and educational effect. The replacement-pressure ratio compares expected losses over the planning horizon with the current active stock. The pathway-coverage ratio compares plausible new entrants, after observed completion and appointment yields, with replacement and growth demand. The persistent-vacancy share identifies funded vacancies exceeding the ordinary recruitment period. The continuity-risk share identifies schools or required subject services experiencing repeated departure, vacancy or unmatched coverage. None has a universal favourable threshold. Authorities should set review thresholds from their appointment calendar, service standards, historical variation and capacity to intervene.

obligations, selection, date, definitions require the a minimum dashboard for national and district authorities analysis to distinguish authority, observed condition and educational effect. Every release needs a reference date, coverage statement, numerator and denominator definitions, revision marker and responsible data steward. Red, amber and green categories may assist operational reading, but the numerical value and reason for classification must remain visible. A colour must not substitute for uncertainty. Suppression rules should prevent identification of individual staff in small schools, while district officers with lawful duties may receive controlled case information necessary to arrange coverage. Public reporting should concentrate on system obligations, not individual blame.[REF-11] [REF-12]

small, regardless, automatic, level define the evidentiary boundary in trigger design, verification and escalation; aggregate completion cannot substitute for a reasoned account of unequal consequence. Three types should be distinguished. A level trigger is crossed when an indicator exceeds a stated value, such as a funded vacancy remaining open beyond the normal appointment window. A change trigger is crossed when deterioration from the previous comparable period exceeds ordinary variation. A conjunction trigger requires several observations, such as rising transfers, unsuccessful recruitment and loss of subject coverage in the same district. Conjunctions often reduce false alarms but may delay recognition; single severe events, including loss of the only teacher at a small school, require immediate action regardless of trend.

confirms, denominator, exists, timetable are material to trigger design, verification and escalation only when the record connects the stated measure to actual delivery and affected learners. The data steward confirms identity matching, reference dates, denominator and late transactions. The establishment authority confirms that the post exists and is funded. The district verifies the school, timetable and interim coverage. The personnel authority establishes recruitment or departure status. The finance authority confirms salary and allowance execution where relevant. The result is classified as confirmed risk, data correction, resolved interruption or unresolved case. The record should preserve both the original signal and its disposition so that the warning rule can later be evaluated.

interruption, compressed, minimum, response change the practical judgement in trigger design, verification and escalation because the responsible body must identify distribution, timing and remedy. A local staffing officer may resolve an isolated short absence. A persistent subject vacancy spanning several schools may require regional deployment, preparation or distance-support measures. A national cluster of expected retirements may require intake, finance and regulatory decisions several years in advance. Emergency interruption may require temporary measures, but temporary appointments, enlarged classes or compressed timetables must carry expiry dates, minimum preparation, supervision and restoration plans. The ease of a temporary response must not turn a warning mechanism into a route around professional standards.

about, instruction, itself, verified are material to trigger design, verification and escalation only when the record connects the stated measure to actual delivery and affected learners. Relevant measures include the share of signals verified within the required time, positive predictive value where outcomes can be observed, false-alarm burden, missed interruptions discovered outside the system, time from warning to coverage, recurrence after closure and distribution of unresolved cases. These measures are not a release judgement on the report. They are ordinary management evidence about whether the early-warning arrangement protects instruction.[REF-11] [REF-14]

functions, identify, authorise, ensure define the evidentiary boundary in comparative interpretation across income and institutional settings; aggregate completion cannot substitute for a reasoned account of unequal consequence. Administrative forms differ. A central civil service, decentralised employer, school-based contract system or mixed public and non-government arrangement may locate these functions in different bodies. Comparison is sound when it aligns the function, population and observation period; it is unsound when it assumes that one administrative label has the same legal meaning everywhere.

sources, pressure, next, projection require the comparative interpretation across income and institutional settings analysis to distinguish authority, observed condition and educational effect. Its comparative value lies in a consistent scenario framework, while national decisions still require school, subject, training and financing detail. The Education for All assessment published in 2007 similarly places teacher recruitment and quality within the remaining distance to 2015. These sources support warning about aggregate pressure; they do not by themselves identify which school will be vacant next term.[REF-13] [REF-15]

dominate, conceal, stable, still require the comparative interpretation across income and institutional settings analysis to distinguish authority, observed condition and educational effect. In systems with stable or declining cohorts, an ageing workforce can still create abrupt subject or location shortages because pupil decline and retirement are not distributed alike. Small island and remote systems face indivisible minimum staffing: a national surplus cannot replace the only qualified teacher required at a distant school. Conflict-affected systems may lose records, facilities and staff simultaneously, making conventional rates least reliable when warning is most necessary.

definitions, without, conclusion, through are material to comparative interpretation across income and institutional settings only when the record connects the stated measure to actual delivery and affected learners. Teacher age, pupil–teacher ratios and prospective youth cohorts describe parts of supply and demand but do not yield a universally accepted shortage measure. This limitation is analytically useful. It directs authorities to publish national vacancy, applicant, attrition and service-gap measures with full definitions, then compare patterns and institutional responses without claiming false equivalence. The proper comparative conclusion may be that two systems face similar educational risk through different administrative mechanisms.[REF-16] [REF-17]

reflect, attribute, placed, because are material to equity, professional conditions and rights only when the record connects the stated measure to actual delivery and affected learners. A national warning system should test whether rural, remote, poor, minority-language, disability-inclusive, conflict-affected and small-school settings experience higher departure, longer recruitment duration, lower qualified-applicant yield or more frequent unmatched assignment. The categories must reflect lawful national data practice and should not be used to attribute risk to learners or communities. They describe obligations placed on the system.

workload, preparation, influence, association change the practical judgement in equity, professional conditions and rights because the responsible body must identify distribution, timing and remedy. Salary level relative to relevant alternatives, payment regularity, housing, travel, safety, workload, class composition, leadership, access to preparation, career progression and participation in decisions may influence recruitment and retention. These are not interchangeable and their association with departures does not prove causation. They are nevertheless legitimate diagnostic evidence. The 1966 Recommendation concerning the Status of Teachers connects employment conditions, professional preparation, consultation and educational quality; it does not support treating teachers as movable units without rights or context.[REF-02]

recognition, identify, continuation, hardship require the equity, professional conditions and rights analysis to distinguish authority, observed condition and educational effect. Hardship allowances may be suitable where a verified cost or amenity difference impedes recruitment, but they require timely payment and evaluation. Local recruitment may improve continuity where candidates meet standards and receive support, but it must not confine disadvantaged areas to a lower qualification rule. Compulsory transfer may fill a post quickly while worsening morale or producing rapid return movement. Housing provision, induction, mentoring, safe transport, workload adjustment and career recognition may operate together. The warning record should identify the hypothesised constraint and the response selected so that continuation depends on evidence.

capacity, children, post, convention change the practical judgement in equity, professional conditions and rights because the responsible body must identify distribution, timing and remedy. The Convention on the Rights of Persons with Disabilities entered into force on 3 May 2008 and requires an inclusive education system. At the present cut-off, this strengthens the case for tracking specialist and support capacity required for inclusion without defining children as a staffing burden. A vacant or unmatched post matters because it interrupts an educational entitlement.[REF-12] [REF-18]

publish, confirm, required, repeated change the practical judgement in immediate programme for the 2011–12 planning cycle because the responsible body must identify distribution, timing and remedy. National authorities should match personnel, payroll, establishment and school-census records; assign unique case identifiers; express part-time service consistently; and publish the residual that cannot be reconciled. Districts should confirm schools with no assigned teacher, no head, no required subject coverage, prolonged vacancies or repeated temporary coverage. Corrections should remain auditable through dated transactions rather than overwriting the starting position.

every, subsequent, promoted, retired are material to immediate programme for the 2011–12 planning cycle only when the record connects the stated measure to actual delivery and affected learners. Every active teacher at the base date should have a subsequent status: continuing in the same school, transferred, promoted outside teaching, on defined leave, retired, resigned, deceased, dismissed, contract ended or unknown. New appointees should be followed from offer to acceptance and reporting. Preparation cohorts should be followed from entry to completion, eligibility, application, appointment and reporting. These linked transitions expose where apparent supply is lost and permit plausible lead-time estimates.

escalation, third, aligned, addresses change the practical judgement in immediate programme for the 2011–12 planning cycle because the responsible body must identify distribution, timing and remedy. A term-opening round addresses immediate coverage. A pre-budget round identifies posts, allowances, preparation places and transition costs. A pre-recruitment round identifies subjects and locations requiring targeted action. A mid-year round verifies persistent vacancies, unplanned departures and the effectiveness of temporary coverage. The schedule should state who receives each signal, the time allowed for verification and the escalation path when responsible institutions disagree.

flow, basis, exposure, coverage are material to immediate programme for the 2011–12 planning cycle only when the record connects the stated measure to actual delivery and affected learners. It should show workforce stock and flow, attrition by reason, vacancy by entitlement basis and duration, recruitment yield, age and contract exposure, geographic and subject concentration, instructional coverage and uncertainty. It should explain breaks in series and refrain from a single international league table. Authorities should accompany the profile with corrective commitments, responsible bodies and next reporting dates. This closes the loop between statistics and educational service.

By 22 October 2011, the global evidence supports urgency but not a universal numerical alarm threshold. Armed conflict, attacks, displacement and institutional interruption intensify the need to distinguish confirmed loss, temporary unavailability and redistribution of teachers. Education for All expansion, teacher retirement, uneven deployment, health and economic pressures, and the difficulty of attracting candidates to particular schools create different risk combinations. The defensible response is a common measurement architecture with locally valid thresholds, rapid verification and professional safeguards. Early warning succeeds when it preserves continuous, appropriately prepared teaching where learners would otherwise lose it; it fails when a favourable national average conceals that loss.[REF-01] [REF-02] [REF-13] [REF-14] [REF-15]

before, preparation, recruitment, lead change the practical judgement in lead-time accounts and the timing of intervention because the responsible body must identify distribution, timing and remedy. Teacher preparation, budget authorisation, establishment creation, recruitment, appointment, relocation and reporting each have a different lead time. A system that observes a retirement on the day a teacher leaves has produced an accurate event record but no useful advance notice. The planning account should therefore work backwards from the date on which instruction must be available. It should identify the latest dates for approving finance, opening recruitment, completing selection, issuing offers, arranging travel or housing, confirming acceptance and preparing interim coverage.

notice, eligibility, definite, about change the practical judgement in lead-time accounts and the timing of intervention because the responsible body must identify distribution, timing and remedy. Contract expiry provides a definite review date but may leave uncertainty about renewal. Pregnancy, illness and family leave require lawful and confidential administration; they should inform substitute capacity without becoming grounds for adverse treatment. Resignation may offer only the contractual notice period. Death, displacement, insecurity and sudden disaster may offer none. The warning system therefore needs both a planned replacement channel and a contingency reserve.

next, immediate, near, affect define the evidentiary boundary in lead-time accounts and the timing of intervention; aggregate completion cannot substitute for a reasoned account of unequal consequence. Increasing admission to a multi-year programme cannot fill next term's vacancy. Authorities should distinguish immediate candidates already eligible for appointment, near-term candidates completing preparation, and prospective candidates whose entry can affect only later years. Completion, eligibility, application, appointment and reporting yields should be applied sequentially. A plan based on admitted students alone will overstate supply where dropout, examination failure, occupational choice, appointment delay or refusal of location is material.[REF-14] [REF-15]

advertisement, separation, general, waiting change the practical judgement in lead-time accounts and the timing of intervention because the responsible body must identify distribution, timing and remedy. A vacancy discovered after national recruitment closes may persist for a full cycle even if many candidates exist. Late fiscal release can produce the same result. The dashboard should measure administrative time as well as labour-market scarcity: days from confirmed need to recruitment authority, advertisement, shortlist, offer, acceptance and reporting. This separation locates delay within the responsible institution. It also prevents a general claim of shortage when qualified applicants are waiting for an appointment decision.

earliest, justify, completion, review are material to lead-time accounts and the timing of intervention only when the record connects the stated measure to actual delivery and affected learners. pathway weakness may justify outreach or additional preparation capacity. Low completion may require student support or programme review. Low application yield may point to employment attractiveness. Low offer acceptance may be concentrated by location or subject. Failure to report may reflect late notice, transport or housing. Early-career exit may call for induction, manageable assignment and leadership support. Each response has its own time to effect and should be evaluated against the transition it was intended to improve.

defined, alternative, alarms, statistical are material to calibration, back-testing and uncertainty only when the record connects the stated measure to actual delivery and affected learners. A simple approach begins with several years of school-level or district-level observations, identifies the signals known before each staffing cycle, and records whether a defined interruption subsequently occurred. The authority can then examine how alternative thresholds would have changed true warnings, false alarms and missed events. The purpose is not to maximise one statistical score. It is to choose a tolerable balance given the educational harm of missed coverage and the administrative cost of verification.

respect, actually, payroll, departure are material to calibration, back-testing and uncertainty only when the record connects the stated measure to actual delivery and affected learners. A model should use only data that would actually have been available when the decision was due. Later corrections, final payroll transactions and explanations discovered after departure cannot be treated as advance knowledge. Where historical records are incomplete, the authority should state that calibration is provisional and begin accumulating a prospective record. Apparent precision from reconstructed data is less useful than a transparent rule subject to scheduled revision.

risks, probable, entire, false define the evidentiary boundary in calibration, back-testing and uncertainty; aggregate completion cannot substitute for a reasoned account of unequal consequence. Missing the probable closure of a one-teacher school may leave an entire community without nearby provision; a false alarm may require only a telephone verification. A national age-structure alert can justify long-range review but need not generate individual case action. A warning concerning a rare specialist may need a lower threshold because replacement time is long. A large urban district may absorb one departure more readily but still face serious subject clusters. Thresholds should therefore be set by decision class, not by a desire for one visually simple national score.

signal, verification, supports, appropriate define the evidentiary boundary in calibration, back-testing and uncertainty; aggregate completion cannot substitute for a reasoned account of unequal consequence. Coverage error, duplicate persons, unmatched identifiers, late transactions, unknown exit reasons and outdated establishments can materially alter results. Authorities should publish a range or quality class where a numerical interval cannot be calculated. They should test whether the warning remains under plausible corrections. A signal that disappears when one late transaction is entered should require verification; a large persistent gap across sources supports stronger action.

suppressed, opened, schools, include change the practical judgement in calibration, back-testing and uncertainty because the responsible body must identify distribution, timing and remedy. Posts may be suppressed, exits miscoded as transfers, recruitment opened briefly to reset duration, or difficult schools administratively combined. Counter-measures include publishing related quantities, retaining transaction histories, using independent statistical review and examining educational service directly. A falling vacancy rate alongside more cancelled lessons is not improvement. The test is whether required, appropriately prepared instruction became more continuous.[REF-06] [REF-11]

The 2011 planning environment requires attention to shocks that can affect teachers and households simultaneously. Rising food and transport costs can reduce the real value and reliability of remuneration, especially for personnel posted far from markets or dependent on long travel. Fiscal pressure can delay hiring, salary release, maintenance and housing. Health burdens can increase absence, mortality, caring responsibilities and training loss. Conflict or displacement can change both pupil demand and teacher availability quickly. These pressures do not justify a speculative attrition estimate; they justify more frequent observation of the transitions through which service may fail.

subjects, compared, matters, exposure are material to continuity under health, food-price and fiscal pressure only when the record connects the stated measure to actual delivery and affected learners. It should also monitor whether schools respond by merging classes, shortening the day, cancelling subjects or relying repeatedly on unprepared personnel. Changes should be compared with the same period of prior years where seasonality matters. National economic indicators can identify exposure, but school and personnel records establish the educational consequence.

willing, assignment, mobile, eligibility define the evidentiary boundary in continuity under health, food-price and fiscal pressure; aggregate completion cannot substitute for a reasoned account of unequal consequence. A contingency roster may include qualified retired teachers willing to return temporarily, teachers available for short assignment, supervised candidates near completion and mobile specialist teams. The rules should define eligibility, safeguarding, remuneration, duration, supervision and return to normal staffing. Community or volunteer assistance can support schools but should not be counted as equivalent teacher capacity unless it meets the applicable professional definition. Emergency measures must not convert temporary necessity into a permanent lower standard for disadvantaged learners.

disputes, coverage, responsibility, releases are material to continuity under health, food-price and fiscal pressure only when the record connects the stated measure to actual delivery and affected learners. Finance ministries control releases; public-service bodies may control establishments; education ministries set curriculum and teacher policy; training institutions control programme capacity; local authorities and school leaders observe service interruption. A warning that stops at the statistical office has not protected instruction. Each high-risk category should have a pre-agreed communication path and a body authorised to decide. Disputes over records or responsibility should have a time limit and an interim coverage rule.

coverage, distribution, restraint, leaving define the evidentiary boundary in continuity under health, food-price and fiscal pressure; aggregate completion cannot substitute for a reasoned account of unequal consequence. Leaving a post vacant may appear to save salary while increasing class size, dropout risk, replacement costs, supervision burden and inequality. Conversely, indiscriminate recruitment can create an unsustainable salary liability and crowd out materials or maintenance. Scenario comparison should show the cost of prevention, temporary coverage, delayed appointment and prolonged interruption. The educational consequence and distribution should accompany the financial result.

cutoff, reporting, definitions, attributing are material to continuity under health, food-price and fiscal pressure only when the record connects the stated measure to actual delivery and affected learners. Authorities should shorten reporting intervals where shocks are intensifying, preserve definitions so that change remains interpretable, and avoid attributing an individual departure to a macroeconomic pressure without case evidence. The early-warning framework is designed to reveal accumulating exposure and service loss soon enough for proportionate action. It does not transform association into certainty, nor does it permit a crisis narrative to displace professional rights, due procedure or minimum educational conditions.[REF-02] [REF-03] [REF-13]
