ICEQC-R-2014-08 — Measuring Adult Participation in Education and Training

Defining the adult reference population establishes the meaning of the adult reference population for persons at or above a stated lower age. For defining the adult reference population, the direct measure is participation rate, but the public claim depends on more than a label. In examining defining the adult reference population, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on defining the adult reference population, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning defining the adult reference population, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-03] [REF-07] [REF-17]

The principal error in defining the adult reference population is that age thresholds and exclusions differ across sources. In examining defining the adult reference population, this changes both numerator and interpretation. Within reporting on defining the adult reference population, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning defining the adult reference population, the authority should list plausible inclusion and exclusion routes for the adult reference population, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-02] [REF-03]

The operational rule for defining the adult reference population is to state the age range, residence rule and institutional populations covered. Within reporting on defining the adult reference population, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning defining the adult reference population, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting defining the adult reference population, where ongoing activities cross the reporting boundary, their status must be defined consistently. For decisions about defining the adult reference population, these decisions should be fixed before national or group results are reviewed, since retrospective boundary changes can turn policy preference into an apparently technical choice.[REF-03] [REF-07]

Evidence for the adult reference population should be selected according to coverage. For evidence concerning defining the adult reference population, household surveys can represent adults outside institutions but rely on recall, proxy response and a household frame. In interpreting defining the adult reference population, provider records describe courses and attendance in detail but usually omit adults and providers outside the reporting system. For decisions about defining the adult reference population, employer evidence can identify funded workplace learning but not the entire labour force or personal learning. Within the scope of defining the adult reference population, for defining the adult reference population, each value should carry a coverage statement and any comparison should begin with a map of differences in population, activity and dates.[REF-07] [REF-17]

Equity analysis of defining the adult reference population should preserve the level for every reported group, not only a parity ratio. In interpreting defining the adult reference population, the relevant comparison may involve age, sex, prior education, employment, income, location, language, migration or disability, depending on the barrier and policy authority. For decisions about defining the adult reference population, selected intersections can reveal compounded exclusion, but a small estimate requires visible uncertainty and safe disclosure. Within the scope of defining the adult reference population, where evidence is unavailable, the report should describe the missing population and the plan to observe it. For responsible use of defining the adult reference population, statistical silence must not be treated as evidence that opportunity is equal for the persons at or above a stated lower age.[REF-02] [REF-17]

Fitness of the participation rate requires tests of question comprehension, classification consistency, response, weighting, precision and change over time. For decisions about defining the adult reference population, for defining the adult reference population, sensitivity to the reference period and activity threshold should be examined where feasible. Within the scope of defining the adult reference population, an apparent country difference may reflect prompting or scope rather than adult behaviour. For responsible use of defining the adult reference population, an apparent annual rise may result from a new question or the addition of training providers. For defining the adult reference population, metadata should be released with the value, and a series should be visibly broken when the evidence cannot support continuity. In examining defining the adult reference population, this restraint increases rather than diminishes the usefulness of comparison.[REF-03] [REF-07] [REF-17]

Interpretation of defining the adult reference population should proceed from observation to explanation and only then to attribution. Within the scope of defining the adult reference population, the observation may be a level or group gap in participation rate. For responsible use of defining the adult reference population, possible explanations include availability, cost, employer support, schedule, transport, care, accessibility, language, confidence and prior educational experience, as well as source error. For defining the adult reference population, descriptive evidence cannot decide among them alone. In examining defining the adult reference population, the report should name competing explanations, show what evidence supports each, and reject deficit claims about adults until institutional conditions and measurement limits have been tested.[REF-02] [REF-03] [REF-07]

Public responsibility completes defining the adult reference population. For responsible use of defining the adult reference population, a material shortfall should be linked to the body able to change provision, finance, information, recognition, accommodation or data quality. For defining the adult reference population, the response should specify authority, resources, timing and a later measure of reach and continuity. In examining defining the adult reference population, if the estimate is too uncertain for service action, a strengthened sample, revised question or targeted study may be the immediate duty. Within reporting on defining the adult reference population, in either case, reporting on the adult reference population should conclude with an owned decision and a correction route, not an unexplained percentage.[REF-02] [REF-03] [REF-07] [REF-17]

Formal education after initial schooling establishes the meaning of the formal adult education for adults enrolled in recognised programmes. For formal education after initial schooling, the direct measure is formal participation, but the public claim depends on more than a label. In examining formal education after initial schooling, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on formal education after initial schooling, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning formal education after initial schooling, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-04] [REF-05] [REF-06] [REF-14]

The principal error in formal education after initial schooling is that adult status is confused with programme level or previous interruption. In examining formal education after initial schooling, this changes both numerator and interpretation. Within reporting on formal education after initial schooling, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning formal education after initial schooling, the authority should list plausible inclusion and exclusion routes for the formal adult education, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-04] [REF-05]

The operational rule for formal education after initial schooling is to classify the programme, learner age and recognised outcome separately. Within reporting on formal education after initial schooling, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning formal education after initial schooling, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting formal education after initial schooling, where ongoing activities cross the reporting boundary, their status must be defined consistently.

Non-formal education and organised training establishes the meaning of the non-formal learning activity for adults in organised learning outside the formal programme structure. For non-formal education and organised training, the direct measure is non-formal participation, but the public claim depends on more than a label. In examining non-formal education and organised training, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on non-formal education and organised training, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning non-formal education and organised training, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-03] [REF-04] [REF-17]

The principal error in non-formal education and organised training is that short courses, workplace training and community learning are inconsistently included. In examining non-formal education and organised training, this changes both numerator and interpretation. Within reporting on non-formal education and organised training, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning non-formal education and organised training, the authority should list plausible inclusion and exclusion routes for the non-formal learning activity, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-02] [REF-03]

The operational rule for non-formal education and organised training is to require organised intention, provider or facilitation, content and a defined learning period. Within reporting on non-formal education and organised training, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning non-formal education and organised training, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Informal learning and self-directed activity establishes the meaning of the informal learning activity for adults learning outside organised provision. For informal learning and self-directed activity, the direct measure is informal participation, but the public claim depends on more than a label. In examining informal learning and self-directed activity, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on informal learning and self-directed activity, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning informal learning and self-directed activity, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-04] [REF-14] [REF-20]

The principal error in informal learning and self-directed activity is that ordinary information seeking is counted as purposeful learning or meaningful self-learning is omitted. In examining informal learning and self-directed activity, this changes both numerator and interpretation. Within reporting on informal learning and self-directed activity, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for informal learning and self-directed activity is to record intention, sustained activity, subject and evidence of engagement without claiming equivalence to a course. Within reporting on informal learning and self-directed activity, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning informal learning and self-directed activity, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Job-related and personal purposes establishes the meaning of the learning purpose for participants reporting work, civic, family or personal aims. For job-related and personal purposes, the direct measure is purpose-specific participation, but the public claim depends on more than a label. In examining job-related and personal purposes, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on job-related and personal purposes, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning job-related and personal purposes, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-12] [REF-17] [REF-19]

The principal error in job-related and personal purposes is that one activity may serve several aims and respondents may report the socially preferred answer. In examining job-related and personal purposes, this changes both numerator and interpretation. Within reporting on job-related and personal purposes, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning job-related and personal purposes, the authority should list plausible inclusion and exclusion routes for the learning purpose, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-02] [REF-12]

The operational rule for job-related and personal purposes is to permit multiple purposes and distinguish stated motivation from observed use or outcome. Within reporting on job-related and personal purposes, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning job-related and personal purposes, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Reference periods and the meaning of current participation establishes the meaning of the participation reference period for adults observed during a stated interval. For reference periods and the meaning of current participation, the direct measure is current or recent participation, but the public claim depends on more than a label. In examining reference periods and the meaning of current participation, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on reference periods and the meaning of current participation, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

The principal error in reference periods and the meaning of current participation is that a four-week rate and a twelve-month rate are compared as if they measured the same exposure. In examining reference periods and the meaning of current participation, this changes both numerator and interpretation. Within reporting on reference periods and the meaning of current participation, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning reference periods and the meaning of current participation, the authority should list plausible inclusion and exclusion routes for the participation reference period, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-07] [REF-09]

The operational rule for reference periods and the meaning of current participation is to publish the exact interval, activity dates and sensitivity to season and recall. Within reporting on reference periods and the meaning of current participation, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning reference periods and the meaning of current participation, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

For reference periods and the meaning of current participation, metadata should be released with the value, and a series should be visibly broken when the evidence cannot support continuity. In examining reference periods and the meaning of current participation, this restraint increases rather than diminishes the usefulness of comparison.[REF-09] [REF-17] [REF-18]

Interpretation of reference periods and the meaning of current participation should proceed from observation to explanation and only then to attribution. Within the scope of reference periods and the meaning of current participation, the observation may be a level or group gap in current or recent participation. For responsible use of reference periods and the meaning of current participation, possible explanations include availability, cost, employer support, schedule, transport, care, accessibility, language, confidence and prior educational experience, as well as source error. For reference periods and the meaning of current participation, descriptive evidence cannot decide among them alone. In examining reference periods and the meaning of current participation, the report should name competing explanations, show what evidence supports each, and reject deficit claims about adults until institutional conditions and measurement limits have been tested.[REF-07] [REF-09] [REF-17]

Public responsibility completes reference periods and the meaning of current participation. For responsible use of reference periods and the meaning of current participation, a material shortfall should be linked to the body able to change provision, finance, information, recognition, accommodation or data quality. For reference periods and the meaning of current participation, the response should specify authority, resources, timing and a later measure of reach and continuity. In examining reference periods and the meaning of current participation, if the estimate is too uncertain for service action, a strengthened sample, revised question or targeted study may be the immediate duty. Within reporting on reference periods and the meaning of current participation, in either case, reporting on the participation reference period should conclude with an owned decision and a correction route, not an unexplained percentage.[REF-07] [REF-09] [REF-17] [REF-18]

Starting an education or training activity establishes the meaning of the activity entry for adults beginning at least one eligible activity. For starting an education or training activity, the direct measure is entry rate, but the public claim depends on more than a label. In examining starting an education or training activity, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on starting an education or training activity, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning starting an education or training activity, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-03] [REF-14] [REF-17]

The principal error in starting an education or training activity is that registration is recorded although the person never attends or receives material. In examining starting an education or training activity, this changes both numerator and interpretation. Within reporting on starting an education or training activity, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning starting an education or training activity, the authority should list plausible inclusion and exclusion routes for the activity entry, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-02] [REF-03]

The operational rule for starting an education or training activity is to set evidence for commencement and distinguish intention, enrolment and first participation. Within reporting on starting an education or training activity, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning starting an education or training activity, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting starting an education or training activity, where ongoing activities cross the reporting boundary, their status must be defined consistently. For decisions about starting an education or training activity, these decisions should be fixed before national or group results are reviewed, since retrospective boundary changes can turn policy preference into an apparently technical choice.[REF-03] [REF-14]

Evidence for the activity entry should be selected according to coverage. For evidence concerning starting an education or training activity, household surveys can represent adults outside institutions but rely on recall, proxy response and a household frame. In interpreting starting an education or training activity, provider records describe courses and attendance in detail but usually omit adults and providers outside the reporting system. For decisions about starting an education or training activity, employer evidence can identify funded workplace learning but not the entire labour force or personal learning. Within the scope of starting an education or training activity, for starting an education or training activity, each value should carry a coverage statement and any comparison should begin with a map of differences in population, activity and dates.[REF-14] [REF-17]

Equity analysis of starting an education or training activity should preserve the level for every reported group, not only a parity ratio. In interpreting starting an education or training activity, the relevant comparison may involve age, sex, prior education, employment, income, location, language, migration or disability, depending on the barrier and policy authority. For decisions about starting an education or training activity, selected intersections can reveal compounded exclusion, but a small estimate requires visible uncertainty and safe disclosure. Within the scope of starting an education or training activity, where evidence is unavailable, the report should describe the missing population and the plan to observe it. For responsible use of starting an education or training activity, statistical silence must not be treated as evidence that opportunity is equal for the adults beginning at least one eligible activity.[REF-02] [REF-17]

Fitness of the entry rate requires tests of question comprehension, classification consistency, response, weighting, precision and change over time. For decisions about starting an education or training activity, for starting an education or training activity, sensitivity to the reference period and activity threshold should be examined where feasible. Within the scope of starting an education or training activity, an apparent country difference may reflect prompting or scope rather than adult behaviour. For responsible use of starting an education or training activity, an apparent annual rise may result from a new question or the addition of training providers.

Attendance and regular engagement establishes the meaning of the regular engagement for participants attending or engaging during scheduled periods. For attendance and regular engagement, the direct measure is attendance intensity, but the public claim depends on more than a label. In examining attendance and regular engagement, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on attendance and regular engagement, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning attendance and regular engagement, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-07] [REF-13] [REF-17]

The principal error in attendance and regular engagement is that one contact is treated as equivalent to sustained attendance. In examining attendance and regular engagement, this changes both numerator and interpretation. Within reporting on attendance and regular engagement, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning attendance and regular engagement, the authority should list plausible inclusion and exclusion routes for the regular engagement, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-02] [REF-07]

The operational rule for attendance and regular engagement is to report attended sessions or hours against the expected opportunity and state the evidence source. Within reporting on attendance and regular engagement, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning attendance and regular engagement, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting attendance and regular engagement, where ongoing activities cross the reporting boundary, their status must be defined consistently.

Duration, hours and learning volume establishes the meaning of the learning volume for participants accumulating time in eligible activities. For duration, hours and learning volume, the direct measure is hours of learning, but the public claim depends on more than a label. In examining duration, hours and learning volume, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on duration, hours and learning volume, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning duration, hours and learning volume, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-14] [REF-17] [REF-22]

The principal error in duration, hours and learning volume is that course length is substituted for hours actually received and very short activities dominate the count. In examining duration, hours and learning volume, this changes both numerator and interpretation. Within reporting on duration, hours and learning volume, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for duration, hours and learning volume is to measure delivered and attended hours and publish the distribution as well as an average. Within reporting on duration, hours and learning volume, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning duration, hours and learning volume, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Multiple activities and repeated participation establishes the meaning of the activity multiplicity for adults undertaking one or more activities. For multiple activities and repeated participation, the direct measure is person and activity rates, but the public claim depends on more than a label. In examining multiple activities and repeated participation, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on multiple activities and repeated participation, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning multiple activities and repeated participation, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-07] [REF-17] [REF-18]

The principal error in multiple activities and repeated participation is that counts of courses are interpreted as counts of people and intensive repeat participation raises the headline. In examining multiple activities and repeated participation, this changes both numerator and interpretation. Within reporting on multiple activities and repeated participation, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning multiple activities and repeated participation, the authority should list plausible inclusion and exclusion routes for the activity multiplicity, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-02] [REF-07]

The operational rule for multiple activities and repeated participation is to publish unique participants, activities per participant and total volume. Within reporting on multiple activities and repeated participation, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning multiple activities and repeated participation, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Completion, interruption and return establishes the meaning of the learning continuity for entrants followed to completion, interruption or return. For completion, interruption and return, the direct measure is completion and persistence, but the public claim depends on more than a label. In examining completion, interruption and return, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on completion, interruption and return, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

The principal error in completion, interruption and return is that short reference windows misclassify ongoing courses and lose adults who return after interruption. In examining completion, interruption and return, this changes both numerator and interpretation. Within reporting on completion, interruption and return, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for completion, interruption and return is to state expected end, completion rule, observed status and later return. Within reporting on completion, interruption and return, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning completion, interruption and return, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Validation and recognised outcomes establishes the meaning of the validated learning for adults seeking or receiving recognition of formal, non-formal or informal learning. For validation and recognised outcomes, the direct measure is recognition rate, but the public claim depends on more than a label. In examining validation and recognised outcomes, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on validation and recognised outcomes, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning validation and recognised outcomes, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-05] [REF-14] [REF-20] [REF-22]

The principal error in validation and recognised outcomes is that participation is assumed to yield a usable credential or recognition is counted without learning evidence. In examining validation and recognised outcomes, this changes both numerator and interpretation. Within reporting on validation and recognised outcomes, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning validation and recognised outcomes, the authority should list plausible inclusion and exclusion routes for the validated learning, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-05] [REF-14]

The operational rule for validation and recognised outcomes is to separate identification, documentation, assessment, certification and later use. Within reporting on validation and recognised outcomes, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning validation and recognised outcomes, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

For responsible use of validation and recognised outcomes, statistical silence must not be treated as evidence that opportunity is equal for the adults seeking or receiving recognition of formal, non-formal or informal learning.[REF-05] [REF-22]

Fitness of the recognition rate requires tests of question comprehension, classification consistency, response, weighting, precision and change over time. For decisions about validation and recognised outcomes, for validation and recognised outcomes, sensitivity to the reference period and activity threshold should be examined where feasible. Within the scope of validation and recognised outcomes, an apparent country difference may reflect prompting or scope rather than adult behaviour. For responsible use of validation and recognised outcomes, an apparent annual rise may result from a new question or the addition of training providers. For validation and recognised outcomes, metadata should be released with the value, and a series should be visibly broken when the evidence cannot support continuity. In examining validation and recognised outcomes, this restraint increases rather than diminishes the usefulness of comparison.[REF-14] [REF-20] [REF-22]

Interpretation of validation and recognised outcomes should proceed from observation to explanation and only then to attribution. Within the scope of validation and recognised outcomes, the observation may be a level or group gap in recognition rate. For responsible use of validation and recognised outcomes, possible explanations include availability, cost, employer support, schedule, transport, care, accessibility, language, confidence and prior educational experience, as well as source error. For validation and recognised outcomes, descriptive evidence cannot decide among them alone. In examining validation and recognised outcomes, the report should name competing explanations, show what evidence supports each, and reject deficit claims about adults until institutional conditions and measurement limits have been tested.[REF-05] [REF-14] [REF-20]

Public responsibility completes validation and recognised outcomes. For responsible use of validation and recognised outcomes, a material shortfall should be linked to the body able to change provision, finance, information, recognition, accommodation or data quality. For validation and recognised outcomes, the response should specify authority, resources, timing and a later measure of reach and continuity. In examining validation and recognised outcomes, if the estimate is too uncertain for service action, a strengthened sample, revised question or targeted study may be the immediate duty. Within reporting on validation and recognised outcomes, in either case, reporting on the validated learning should conclude with an owned decision and a correction route, not an unexplained percentage.[REF-05] [REF-14] [REF-20] [REF-22]

Sex, care and household responsibility establishes the meaning of the sex and care classification for women and men with differing unpaid responsibilities. For sex, care and household responsibility, the direct measure is participation gap, but the public claim depends on more than a label. In examining sex, care and household responsibility, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on sex, care and household responsibility, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning sex, care and household responsibility, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-03] [REF-08] [REF-23]

The principal error in sex, care and household responsibility is that care time, safety and programme schedules remain unobserved behind a sex total. In examining sex, care and household responsibility, this changes both numerator and interpretation. Within reporting on sex, care and household responsibility, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning sex, care and household responsibility, the authority should list plausible inclusion and exclusion routes for the sex and care classification, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-02] [REF-03]

The operational rule for sex, care and household responsibility is to cross-classify sex with care, employment, age and course timing where safe. Within reporting on sex, care and household responsibility, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning sex, care and household responsibility, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting sex, care and household responsibility, where ongoing activities cross the reporting boundary, their status must be defined consistently. For decisions about sex, care and household responsibility, these decisions should be fixed before national or group results are reviewed, since retrospective boundary changes can turn policy preference into an apparently technical choice.[REF-03] [REF-08]

Evidence for the sex and care classification should be selected according to coverage. For evidence concerning sex, care and household responsibility, household surveys can represent adults outside institutions but rely on recall, proxy response and a household frame. In interpreting sex, care and household responsibility, provider records describe courses and attendance in detail but usually omit adults and providers outside the reporting system. For decisions about sex, care and household responsibility, employer evidence can identify funded workplace learning but not the entire labour force or personal learning. Within the scope of sex, care and household responsibility, for sex, care and household responsibility, each value should carry a coverage statement and any comparison should begin with a map of differences in population, activity and dates.[REF-08] [REF-23]

Equity analysis of sex, care and household responsibility should preserve the level for every reported group, not only a parity ratio. In interpreting sex, care and household responsibility, the relevant comparison may involve age, sex, prior education, employment, income, location, language, migration or disability, depending on the barrier and policy authority. For decisions about sex, care and household responsibility, selected intersections can reveal compounded exclusion, but a small estimate requires visible uncertainty and safe disclosure. Within the scope of sex, care and household responsibility, where evidence is unavailable, the report should describe the missing population and the plan to observe it.

Age and stage of adult life establishes the meaning of the adult age distribution for younger, mid-life and older adults. For age and stage of adult life, the direct measure is age-specific participation, but the public claim depends on more than a label. In examining age and stage of adult life, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on age and stage of adult life, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning age and stage of adult life, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-04] [REF-07] [REF-14]

The principal error in age and stage of adult life is that a single broad adult category is driven by younger learners and conceals later-life exclusion. In examining age and stage of adult life, this changes both numerator and interpretation. Within reporting on age and stage of adult life, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning age and stage of adult life, the authority should list plausible inclusion and exclusion routes for the adult age distribution, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-02] [REF-04]

The operational rule for age and stage of adult life is to use meaningful age bands and distinguish cohort, age and period effects. Within reporting on age and stage of adult life, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning age and stage of adult life, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting age and stage of adult life, where ongoing activities cross the reporting boundary, their status must be defined consistently.

Prior education, literacy and foundational skills establishes the meaning of the prior-learning classification for adults with different attainment and literacy histories. For prior education, literacy and foundational skills, the direct measure is participation by prior attainment, but the public claim depends on more than a label. In examining prior education, literacy and foundational skills, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on prior education, literacy and foundational skills, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

The principal error in prior education, literacy and foundational skills is that provision disproportionately reaches those already holding recognised qualifications. In examining prior education, literacy and foundational skills, this changes both numerator and interpretation. Within reporting on prior education, literacy and foundational skills, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for prior education, literacy and foundational skills is to report the participation gradient and specific access to foundational and second-chance learning. Within reporting on prior education, literacy and foundational skills, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning prior education, literacy and foundational skills, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Employment status and conditions of work establishes the meaning of the labour-status classification for employed, unemployed and economically inactive adults. For employment status and conditions of work, the direct measure is work-related participation, but the public claim depends on more than a label. In examining employment status and conditions of work, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on employment status and conditions of work, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

The principal error in employment status and conditions of work is that employer-supported learning is concentrated in stable jobs while irregular workers disappear from workplace records. In examining employment status and conditions of work, this changes both numerator and interpretation. Within reporting on employment status and conditions of work, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for employment status and conditions of work is to separate status, contract conditions, sector, occupation and who paid for the learning. Within reporting on employment status and conditions of work, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation.

Income, location, migration and language establishes the meaning of the socio-territorial classification for adults across household resources, residence, migration and language groups. For income, location, migration and language, the direct measure is equity of participation, but the public claim depends on more than a label. In examining income, location, migration and language, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on income, location, migration and language, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

The principal error in income, location, migration and language is that cost, distance, documentation and language barriers combine but are hidden by national totals. In examining income, location, migration and language, this changes both numerator and interpretation.

Disability, accessibility and accommodation establishes the meaning of the disability-sensitive participation for adults with different functional and accommodation requirements. For disability, accessibility and accommodation, the direct measure is accessible participation, but the public claim depends on more than a label. In examining disability, accessibility and accommodation, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on disability, accessibility and accommodation, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning disability, accessibility and accommodation, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-08] [REF-14] [REF-24]

The principal error in disability, accessibility and accommodation is that provider registers capture only disclosed conditions and exclude people unable to reach the offer. In examining disability, accessibility and accommodation, this changes both numerator and interpretation. Within reporting on disability, accessibility and accommodation, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for disability, accessibility and accommodation is to use respectful functional evidence and report accessibility, accommodation and sustained participation. Within reporting on disability, accessibility and accommodation, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning disability, accessibility and accommodation, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting disability, accessibility and accommodation, where ongoing activities cross the reporting boundary, their status must be defined consistently. For decisions about disability, accessibility and accommodation, these decisions should be fixed before national or group results are reviewed, since retrospective boundary changes can turn policy preference into an apparently technical choice.[REF-08] [REF-14]

Evidence for the disability-sensitive participation should be selected according to coverage. For evidence concerning disability, accessibility and accommodation, household surveys can represent adults outside institutions but rely on recall, proxy response and a household frame. In interpreting disability, accessibility and accommodation, provider records describe courses and attendance in detail but usually omit adults and providers outside the reporting system. For decisions about disability, accessibility and accommodation, employer evidence can identify funded workplace learning but not the entire labour force or personal learning. Within the scope of disability, accessibility and accommodation, for disability, accessibility and accommodation, each value should carry a coverage statement and any comparison should begin with a map of differences in population, activity and dates.[REF-14] [REF-24]

Equity analysis of disability, accessibility and accommodation should preserve the level for every reported group, not only a parity ratio. In interpreting disability, accessibility and accommodation, the relevant comparison may involve age, sex, prior education, employment, income, location, language, migration or disability, depending on the barrier and policy authority. For decisions about disability, accessibility and accommodation, selected intersections can reveal compounded exclusion, but a small estimate requires visible uncertainty and safe disclosure. Within the scope of disability, accessibility and accommodation, where evidence is unavailable, the report should describe the missing population and the plan to observe it. For responsible use of disability, accessibility and accommodation, statistical silence must not be treated as evidence that opportunity is equal for the adults with different functional and accommodation requirements.[REF-02] [REF-24]

Fitness of the accessible participation requires tests of question comprehension, classification consistency, response, weighting, precision and change over time. For decisions about disability, accessibility and accommodation, for disability, accessibility and accommodation, sensitivity to the reference period and activity threshold should be examined where feasible. Within the scope of disability, accessibility and accommodation, an apparent country difference may reflect prompting or scope rather than adult behaviour. For responsible use of disability, accessibility and accommodation, an apparent annual rise may result from a new question or the addition of training providers. For disability, accessibility and accommodation, metadata should be released with the value, and a series should be visibly broken when the evidence cannot support continuity. In examining disability, accessibility and accommodation, this restraint increases rather than diminishes the usefulness of comparison.[REF-08] [REF-14] [REF-24]

Interpretation of disability, accessibility and accommodation should proceed from observation to explanation and only then to attribution. Within the scope of disability, accessibility and accommodation, the observation may be a level or group gap in accessible participation. For responsible use of disability, accessibility and accommodation, possible explanations include availability, cost, employer support, schedule, transport, care, accessibility, language, confidence and prior educational experience, as well as source error. For disability, accessibility and accommodation, descriptive evidence cannot decide among them alone. In examining disability, accessibility and accommodation, the report should name competing explanations, show what evidence supports each, and reject deficit claims about adults until institutional conditions and measurement limits have been tested.[REF-02] [REF-08] [REF-14]

Public responsibility completes disability, accessibility and accommodation. For responsible use of disability, accessibility and accommodation, a material shortfall should be linked to the body able to change provision, finance, information, recognition, accommodation or data quality. For disability, accessibility and accommodation, the response should specify authority, resources, timing and a later measure of reach and continuity. In examining disability, accessibility and accommodation, if the estimate is too uncertain for service action, a strengthened sample, revised question or targeted study may be the immediate duty. Within reporting on disability, accessibility and accommodation, in either case, reporting on the disability-sensitive participation should conclude with an owned decision and a correction route, not an unexplained percentage.[REF-02] [REF-08] [REF-14] [REF-24]

Dedicated adult education surveys establishes the meaning of the adult education survey for sampled adults responding to detailed activity questions. For dedicated adult education surveys, the direct measure is survey participation estimate, but the public claim depends on more than a label. In examining dedicated adult education surveys, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on dedicated adult education surveys, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning dedicated adult education surveys, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-07] [REF-09] [REF-17] [REF-18]

The principal error in dedicated adult education surveys is that long activity lists increase recall burden and cross-country instruments classify activities differently. In examining dedicated adult education surveys, this changes both numerator and interpretation. Within reporting on dedicated adult education surveys, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning dedicated adult education surveys, the authority should list plausible inclusion and exclusion routes for the adult education survey, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-07] [REF-09]

The operational rule for dedicated adult education surveys is to use tested prompts, bounded reference periods, documented coding and response-quality checks. Within reporting on dedicated adult education surveys, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning dedicated adult education surveys, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Labour-force and general household surveys establishes the meaning of the household survey module for adults in sampled private households. For labour-force and general household surveys, the direct measure is short-module participation, but the public claim depends on more than a label. In examining labour-force and general household surveys, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on labour-force and general household surveys, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

The principal error in labour-force and general household surveys is that few questions omit non-job learning and exclude institutional or unstable populations. In examining labour-force and general household surveys, this changes both numerator and interpretation. Within reporting on labour-force and general household surveys, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for labour-force and general household surveys is to state question wording, household coverage and differences from dedicated surveys. Within reporting on labour-force and general household surveys, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning labour-force and general household surveys, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Provider and programme records establishes the meaning of the provider record for registered learners and activities in reporting institutions. For provider and programme records, the direct measure is administrative participation, but the public claim depends on more than a label. In examining provider and programme records, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on provider and programme records, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

The principal error in provider and programme records is that duplicate registrations, unknown age and incomplete private or community coverage inflate or narrow totals. In examining provider and programme records, this changes both numerator and interpretation. Within reporting on provider and programme records, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for provider and programme records is to use unique persons where lawful and publish provider coverage, reporting completeness and activity definitions. Within reporting on provider and programme records, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning provider and programme records, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Employer-supported training evidence establishes the meaning of the employer training record for workers in reporting enterprises. For employer-supported training evidence, the direct measure is workplace participation, but the public claim depends on more than a label. In examining employer-supported training evidence, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred.

The principal error in employer-supported training evidence is that small enterprises, informal work and non-employer learning are omitted while scheduled hours replace attendance. In examining employer-supported training evidence, this changes both numerator and interpretation.

Time-use and learning diaries establishes the meaning of the time-use evidence for adults recording activities over short observation periods. For time-use and learning diaries, the direct measure is daily learning time, but the public claim depends on more than a label. In examining time-use and learning diaries, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on time-use and learning diaries, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

Triangulation and carefully governed linkage establishes the meaning of the cross-source evidence for persons and activities represented differently across sources. For triangulation and carefully governed linkage, the direct measure is reconciled participation, but the public claim depends on more than a label. In examining triangulation and carefully governed linkage, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on triangulation and carefully governed linkage, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning triangulation and carefully governed linkage, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-08] [REF-09] [REF-17] [REF-18]

The principal error in triangulation and carefully governed linkage is that similar labels invite direct merging despite different units, dates and coverage. In examining triangulation and carefully governed linkage, this changes both numerator and interpretation. Within reporting on triangulation and carefully governed linkage, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning triangulation and carefully governed linkage, the authority should list plausible inclusion and exclusion routes for the cross-source evidence, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-08] [REF-09]

The operational rule for triangulation and carefully governed linkage is to map definitions first and link only with lawful purpose, minimum variables and protected access. Within reporting on triangulation and carefully governed linkage, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning triangulation and carefully governed linkage, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting triangulation and carefully governed linkage, where ongoing activities cross the reporting boundary, their status must be defined consistently. For decisions about triangulation and carefully governed linkage, these decisions should be fixed before national or group results are reviewed, since retrospective boundary changes can turn policy preference into an apparently technical choice.[REF-09] [REF-17]

Evidence for the cross-source evidence should be selected according to coverage. For evidence concerning triangulation and carefully governed linkage, household surveys can represent adults outside institutions but rely on recall, proxy response and a household frame. In interpreting triangulation and carefully governed linkage, provider records describe courses and attendance in detail but usually omit adults and providers outside the reporting system. For decisions about triangulation and carefully governed linkage, employer evidence can identify funded workplace learning but not the entire labour force or personal learning. Within the scope of triangulation and carefully governed linkage, for triangulation and carefully governed linkage, each value should carry a coverage statement and any comparison should begin with a map of differences in population, activity and dates.[REF-17] [REF-18]

Equity analysis of triangulation and carefully governed linkage should preserve the level for every reported group, not only a parity ratio. In interpreting triangulation and carefully governed linkage, the relevant comparison may involve age, sex, prior education, employment, income, location, language, migration or disability, depending on the barrier and policy authority. For decisions about triangulation and carefully governed linkage, selected intersections can reveal compounded exclusion, but a small estimate requires visible uncertainty and safe disclosure. Within the scope of triangulation and carefully governed linkage, where evidence is unavailable, the report should describe the missing population and the plan to observe it. For responsible use of triangulation and carefully governed linkage, statistical silence must not be treated as evidence that opportunity is equal for the persons and activities represented differently across sources.[REF-08] [REF-18]

Fitness of the reconciled participation requires tests of question comprehension, classification consistency, response, weighting, precision and change over time. For decisions about triangulation and carefully governed linkage, for triangulation and carefully governed linkage, sensitivity to the reference period and activity threshold should be examined where feasible. Within the scope of triangulation and carefully governed linkage, an apparent country difference may reflect prompting or scope rather than adult behaviour. For responsible use of triangulation and carefully governed linkage, an apparent annual rise may result from a new question or the addition of training providers. For triangulation and carefully governed linkage, metadata should be released with the value, and a series should be visibly broken when the evidence cannot support continuity. In examining triangulation and carefully governed linkage, this restraint increases rather than diminishes the usefulness of comparison.[REF-09] [REF-17] [REF-18]

Interpretation of triangulation and carefully governed linkage should proceed from observation to explanation and only then to attribution. Within the scope of triangulation and carefully governed linkage, the observation may be a level or group gap in reconciled participation. For responsible use of triangulation and carefully governed linkage, possible explanations include availability, cost, employer support, schedule, transport, care, accessibility, language, confidence and prior educational experience, as well as source error. For triangulation and carefully governed linkage, descriptive evidence cannot decide among them alone. In examining triangulation and carefully governed linkage, the report should name competing explanations, show what evidence supports each, and reject deficit claims about adults until institutional conditions and measurement limits have been tested.[REF-08] [REF-09] [REF-17]

Public responsibility completes triangulation and carefully governed linkage. For responsible use of triangulation and carefully governed linkage, a material shortfall should be linked to the body able to change provision, finance, information, recognition, accommodation or data quality. For triangulation and carefully governed linkage, the response should specify authority, resources, timing and a later measure of reach and continuity. In examining triangulation and carefully governed linkage, if the estimate is too uncertain for service action, a strengthened sample, revised question or targeted study may be the immediate duty. Within reporting on triangulation and carefully governed linkage, in either case, reporting on the cross-source evidence should conclude with an owned decision and a correction route, not an unexplained percentage.[REF-08] [REF-09] [REF-17] [REF-18]

Numerators, denominators and eligible opportunity establishes the meaning of the rate construction for adults eligible for the stated activity concept. For numerators, denominators and eligible opportunity, the direct measure is participation numerator and denominator, but the public claim depends on more than a label. In examining numerators, denominators and eligible opportunity, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on numerators, denominators and eligible opportunity, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning numerators, denominators and eligible opportunity, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-06] [REF-07] [REF-09] [REF-17]

The principal error in numerators, denominators and eligible opportunity is that a numerator from providers is divided by a resident population that does not share the same coverage. In examining numerators, denominators and eligible opportunity, this changes both numerator and interpretation. Within reporting on numerators, denominators and eligible opportunity, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

Activity classification and coding rules establishes the meaning of the activity classification for reported courses, training and self-learning episodes. For activity classification and coding rules, the direct measure is classified participation, but the public claim depends on more than a label. In examining activity classification and coding rules, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on activity classification and coding rules, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

The principal error in activity classification and coding rules is that coders assign the same description differently or respondents cannot distinguish formal and non-formal routes. In examining activity classification and coding rules, this changes both numerator and interpretation. Within reporting on activity classification and coding rules, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for activity classification and coding rules is to publish decision rules, difficult examples, residual categories and coding reliability. Within reporting on activity classification and coding rules, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation.

Weights, non-response and population totals establishes the meaning of the weighted survey estimate for sample respondents representing the adult population. For weights, non-response and population totals, the direct measure is weighted participation, but the public claim depends on more than a label. In examining weights, non-response and population totals, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on weights, non-response and population totals, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning weights, non-response and population totals, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-07] [REF-09] [REF-17] [REF-18]

The principal error in weights, non-response and population totals is that non-participants or disadvantaged adults respond less often and unweighted data overstate opportunity. In examining weights, non-response and population totals, this changes both numerator and interpretation. Within reporting on weights, non-response and population totals, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

Sample size, precision and intersecting groups establishes the meaning of the precision of disaggregation for priority population groups and intersections. For sample size, precision and intersecting groups, the direct measure is group participation estimate, but the public claim depends on more than a label. In examining sample size, precision and intersecting groups, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on sample size, precision and intersecting groups, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

The principal error in sample size, precision and intersecting groups is that small cells create unstable rankings and apparent changes within sampling variation. In examining sample size, precision and intersecting groups, this changes both numerator and interpretation.

Comparability across countries and years establishes the meaning of the comparability assessment for jurisdictions and periods using a common indicator label. For comparability across countries and years, the direct measure is comparative participation, but the public claim depends on more than a label.

In examining comparability across countries and years, this restraint increases rather than diminishes the usefulness of comparison.[REF-09] [REF-15] [REF-17]

Interpretation of comparability across countries and years should proceed from observation to explanation and only then to attribution. Within the scope of comparability across countries and years, the observation may be a level or group gap in comparative participation. For responsible use of comparability across countries and years, possible explanations include availability, cost, employer support, schedule, transport, care, accessibility, language, confidence and prior educational experience, as well as source error. For comparability across countries and years, descriptive evidence cannot decide among them alone. In examining comparability across countries and years, the report should name competing explanations, show what evidence supports each, and reject deficit claims about adults until institutional conditions and measurement limits have been tested.[REF-06] [REF-09] [REF-15]

Public responsibility completes comparability across countries and years. For responsible use of comparability across countries and years, a material shortfall should be linked to the body able to change provision, finance, information, recognition, accommodation or data quality. For comparability across countries and years, the response should specify authority, resources, timing and a later measure of reach and continuity. In examining comparability across countries and years, if the estimate is too uncertain for service action, a strengthened sample, revised question or targeted study may be the immediate duty. Within reporting on comparability across countries and years, in either case, reporting on the comparability assessment should conclude with an owned decision and a correction route, not an unexplained percentage.[REF-06] [REF-09] [REF-15] [REF-17]

Missing data, imputation and revision establishes the meaning of the data-quality account for records or responses absent from the estimate. For missing data, imputation and revision, the direct measure is published and revised participation, but the public claim depends on more than a label. In examining missing data, imputation and revision, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on missing data, imputation and revision, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning missing data, imputation and revision, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-07] [REF-09] [REF-17] [REF-18]

The principal error in missing data, imputation and revision is that missingness is treated as non-participation and silent revisions change a trend. In examining missing data, imputation and revision, this changes both numerator and interpretation. Within reporting on missing data, imputation and revision, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning missing data, imputation and revision, the authority should list plausible inclusion and exclusion routes for the data-quality account, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-07] [REF-09]

The operational rule for missing data, imputation and revision is to report missing patterns, imputation assumptions, revision dates and effects on group findings. Within reporting on missing data, imputation and revision, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning missing data, imputation and revision, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting missing data, imputation and revision, where ongoing activities cross the reporting boundary, their status must be defined consistently. For decisions about missing data, imputation and revision, these decisions should be fixed before national or group results are reviewed, since retrospective boundary changes can turn policy preference into an apparently technical choice.[REF-09] [REF-17]

Evidence for the data-quality account should be selected according to coverage. For evidence concerning missing data, imputation and revision, household surveys can represent adults outside institutions but rely on recall, proxy response and a household frame. In interpreting missing data, imputation and revision, provider records describe courses and attendance in detail but usually omit adults and providers outside the reporting system. For decisions about missing data, imputation and revision, employer evidence can identify funded workplace learning but not the entire labour force or personal learning. Within the scope of missing data, imputation and revision, for missing data, imputation and revision, each value should carry a coverage statement and any comparison should begin with a map of differences in population, activity and dates.[REF-17] [REF-18]

Equity analysis of missing data, imputation and revision should preserve the level for every reported group, not only a parity ratio. In interpreting missing data, imputation and revision, the relevant comparison may involve age, sex, prior education, employment, income, location, language, migration or disability, depending on the barrier and policy authority. For decisions about missing data, imputation and revision, selected intersections can reveal compounded exclusion, but a small estimate requires visible uncertainty and safe disclosure. Within the scope of missing data, imputation and revision, where evidence is unavailable, the report should describe the missing population and the plan to observe it. For responsible use of missing data, imputation and revision, statistical silence must not be treated as evidence that opportunity is equal for the records or responses absent from the estimate.[REF-07] [REF-18]

Fitness of the published and revised participation requires tests of question comprehension, classification consistency, response, weighting, precision and change over time. For decisions about missing data, imputation and revision, for missing data, imputation and revision, sensitivity to the reference period and activity threshold should be examined where feasible. Within the scope of missing data, imputation and revision, an apparent country difference may reflect prompting or scope rather than adult behaviour. For responsible use of missing data, imputation and revision, an apparent annual rise may result from a new question or the addition of training providers. For missing data, imputation and revision, metadata should be released with the value, and a series should be visibly broken when the evidence cannot support continuity.

A minimum indicator family establishes the meaning of the core adult-learning release for the adult population and priority groups. For a minimum indicator family, the direct measure is participation, volume, completion and recognition, but the public claim depends on more than a label. In examining a minimum indicator family, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on a minimum indicator family, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning a minimum indicator family, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-03] [REF-14] [REF-17]

The principal error in a minimum indicator family is that one headline percentage becomes the sole account of lifelong learning. In examining a minimum indicator family, this changes both numerator and interpretation. Within reporting on a minimum indicator family, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning a minimum indicator family, the authority should list plausible inclusion and exclusion routes for the core adult-learning release, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-02] [REF-03]

The operational rule for a minimum indicator family is to publish levels, group gaps, hours, activity types, completion, funding and uncertainty. Within reporting on a minimum indicator family, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning a minimum indicator family, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Quality and relevance beside participation establishes the meaning of the participation-quality account for adult learners in different activities. For quality and relevance beside participation, the direct measure is teaching, support and relevance, but the public claim depends on more than a label. In examining quality and relevance beside participation, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on quality and relevance beside participation, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning quality and relevance beside participation, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-01] [REF-03] [REF-13] [REF-19]

The principal error in quality and relevance beside participation is that higher participation is praised although provision is inaccessible, too brief or unrelated to stated aims. In examining quality and relevance beside participation, this changes both numerator and interpretation. Within reporting on quality and relevance beside participation, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning quality and relevance beside participation, the authority should list plausible inclusion and exclusion routes for the participation-quality account, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-01] [REF-03]

The operational rule for quality and relevance beside participation is to pair reach with learner support, completion, perceived use and recognised outcomes. Within reporting on quality and relevance beside participation, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning quality and relevance beside participation, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours.

Costs, finance and who pays establishes the meaning of the adult-learning finance incidence for learners, households, employers and public bodies. For costs, finance and who pays, the direct measure is expenditure and cost barrier, but the public claim depends on more than a label. In examining costs, finance and who pays, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on costs, finance and who pays, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning costs, finance and who pays, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-02] [REF-03] [REF-14] [REF-19]

The principal error in costs, finance and who pays is that public totals conceal fees, unpaid time and unequal employer support. In examining costs, finance and who pays, this changes both numerator and interpretation. Within reporting on costs, finance and who pays, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for costs, finance and who pays is to report funding source, participant cost, paid time and support by group and activity. Within reporting on costs, finance and who pays, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation.

Education for sustainable development and community learning establishes the meaning of the sustainability-oriented adult learning for adults in community, civic and occupational settings. For education for sustainable development and community learning, the direct measure is participation in sustainability learning, but the public claim depends on more than a label. In examining education for sustainable development and community learning, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on education for sustainable development and community learning, the first duty is therefore to write the indicator in ordinary language before assigning a formula.

Post-2015 targets and the leave-no-one-behind test establishes the meaning of the future-target baseline for adult groups facing unequal access to learning. For post-2015 targets and the leave-no-one-behind test, the direct measure is distributional participation target, but the public claim depends on more than a label. In examining post-2015 targets and the leave-no-one-behind test, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on post-2015 targets and the leave-no-one-behind test, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning post-2015 targets and the leave-no-one-behind test, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-08] [REF-10] [REF-11] [REF-23]

The principal error in post-2015 targets and the leave-no-one-behind test is that a national target is met through gains among adults already most likely to participate. In examining post-2015 targets and the leave-no-one-behind test, this changes both numerator and interpretation. Within reporting on post-2015 targets and the leave-no-one-behind test, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible.

The operational rule for post-2015 targets and the leave-no-one-behind test is to set group baselines, minimum floors and milestones without implying outcomes not yet agreed. Within reporting on post-2015 targets and the leave-no-one-behind test, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning post-2015 targets and the leave-no-one-behind test, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting post-2015 targets and the leave-no-one-behind test, where ongoing activities cross the reporting boundary, their status must be defined consistently. For decisions about post-2015 targets and the leave-no-one-behind test, these decisions should be fixed before national or group results are reviewed, since retrospective boundary changes can turn policy preference into an apparently technical choice.[REF-10] [REF-11]

Evidence for the future-target baseline should be selected according to coverage. For evidence concerning post-2015 targets and the leave-no-one-behind test, household surveys can represent adults outside institutions but rely on recall, proxy response and a household frame. In interpreting post-2015 targets and the leave-no-one-behind test, provider records describe courses and attendance in detail but usually omit adults and providers outside the reporting system. For decisions about post-2015 targets and the leave-no-one-behind test, employer evidence can identify funded workplace learning but not the entire labour force or personal learning. Within the scope of post-2015 targets and the leave-no-one-behind test, for post-2015 targets and the leave-no-one-behind test, each value should carry a coverage statement and any comparison should begin with a map of differences in population, activity and dates.[REF-11] [REF-23]

Equity analysis of post-2015 targets and the leave-no-one-behind test should preserve the level for every reported group, not only a parity ratio. In interpreting post-2015 targets and the leave-no-one-behind test, the relevant comparison may involve age, sex, prior education, employment, income, location, language, migration or disability, depending on the barrier and policy authority. For decisions about post-2015 targets and the leave-no-one-behind test, selected intersections can reveal compounded exclusion, but a small estimate requires visible uncertainty and safe disclosure. Within the scope of post-2015 targets and the leave-no-one-behind test, where evidence is unavailable, the report should describe the missing population and the plan to observe it. For responsible use of post-2015 targets and the leave-no-one-behind test, statistical silence must not be treated as evidence that opportunity is equal for the adult groups facing unequal access to learning.[REF-08] [REF-23]

Fitness of the distributional participation target requires tests of question comprehension, classification consistency, response, weighting, precision and change over time. For decisions about post-2015 targets and the leave-no-one-behind test, for post-2015 targets and the leave-no-one-behind test, sensitivity to the reference period and activity threshold should be examined where feasible. Within the scope of post-2015 targets and the leave-no-one-behind test, an apparent country difference may reflect prompting or scope rather than adult behaviour. For responsible use of post-2015 targets and the leave-no-one-behind test, an apparent annual rise may result from a new question or the addition of training providers. For post-2015 targets and the leave-no-one-behind test, metadata should be released with the value, and a series should be visibly broken when the evidence cannot support continuity. In examining post-2015 targets and the leave-no-one-behind test, this restraint increases rather than diminishes the usefulness of comparison.[REF-10] [REF-11] [REF-23]

Interpretation of post-2015 targets and the leave-no-one-behind test should proceed from observation to explanation and only then to attribution. Within the scope of post-2015 targets and the leave-no-one-behind test, the observation may be a level or group gap in distributional participation target. For responsible use of post-2015 targets and the leave-no-one-behind test, possible explanations include availability, cost, employer support, schedule, transport, care, accessibility, language, confidence and prior educational experience, as well as source error. For post-2015 targets and the leave-no-one-behind test, descriptive evidence cannot decide among them alone. In examining post-2015 targets and the leave-no-one-behind test, the report should name competing explanations, show what evidence supports each, and reject deficit claims about adults until institutional conditions and measurement limits have been tested.[REF-08] [REF-10] [REF-11]

Public responsibility completes post-2015 targets and the leave-no-one-behind test. For responsible use of post-2015 targets and the leave-no-one-behind test, a material shortfall should be linked to the body able to change provision, finance, information, recognition, accommodation or data quality. For post-2015 targets and the leave-no-one-behind test, the response should specify authority, resources, timing and a later measure of reach and continuity. In examining post-2015 targets and the leave-no-one-behind test, if the estimate is too uncertain for service action, a strengthened sample, revised question or targeted study may be the immediate duty. Within reporting on post-2015 targets and the leave-no-one-behind test, in either case, reporting on the future-target baseline should conclude with an owned decision and a correction route, not an unexplained percentage.[REF-08] [REF-10] [REF-11] [REF-23]

Statistical governance, privacy and correction establishes the meaning of the public evidence governance for people represented in adult-learning statistics. For statistical governance, privacy and correction, the direct measure is release, confidentiality and revision, but the public claim depends on more than a label. In examining statistical governance, privacy and correction, it depends on the person or activity counted, the lower and upper age boundaries, the time interval, the setting, and the evidence that participation occurred. Within reporting on statistical governance, privacy and correction, the first duty is therefore to write the indicator in ordinary language before assigning a formula. For evidence concerning statistical governance, privacy and correction, that statement should be intelligible to adult learners and providers as well as statisticians, and it should make clear what kind of opportunity the resulting value can and cannot represent.[REF-08] [REF-09] [REF-16] [REF-18]

The principal error in statistical governance, privacy and correction is that sensitive characteristics are exposed, inconvenient results are delayed or errors remain uncorrected. In examining statistical governance, privacy and correction, this changes both numerator and interpretation. Within reporting on statistical governance, privacy and correction, it can overstate access by counting offers, registrations or scheduled hours that adults did not use; it can understate participation by excluding community, workplace or second-chance routes; or it can distribute error unevenly when disadvantaged adults are less visible. For evidence concerning statistical governance, privacy and correction, the authority should list plausible inclusion and exclusion routes for the public evidence governance, identify which are material, and avoid describing a residual category as learner choice where cost, time, accessibility or coverage has not been examined.[REF-08] [REF-09]

The operational rule for statistical governance, privacy and correction is to protect professional authority, safe disclosure, public calendars, revision notices and complaint routes. Within reporting on statistical governance, privacy and correction, a complete specification should name the observation unit, eligible population, qualifying activity, minimum evidence, reference period, source and calculation. For evidence concerning statistical governance, privacy and correction, where several activities are permitted, the rule must state whether a person is counted once, once per activity or according to accumulated hours. In interpreting statistical governance, privacy and correction, where ongoing activities cross the reporting boundary, their status must be defined consistently. For decisions about statistical governance, privacy and correction, these decisions should be fixed before national or group results are reviewed, since retrospective boundary changes can turn policy preference into an apparently technical choice.[REF-09] [REF-16]
