Education at a Glance 2025 supplies comparable system indicators that require careful separation from institutional performance and individual learner outcomes.
What comparative attainment indicators reveal
Education at a Glance provides a structured comparative view of participation, attainment, completion, labour-market outcomes, finance and education conditions. Its indicators can establish context and identify questions. They cannot, without local evidence, attribute a national pattern to one provider or predict an individual learner’s outcome.[S1]
Education at a Glance brings access, attainment, completion, labour-market outcomes, finance and the teaching workforce into one comparative record. The indicators help locate a system pattern, but they do not establish the performance of a named institution. An institutional decision needs a population and outcome definition aligned with the OECD measure before any comparison is meaningful.[S1]
Definitions and tables in Education at a Glance
The edition gives particular attention to tertiary education and connects attainment with completion, field, employment and earnings measures. Tables use defined denominators, age groups and reference periods. Reliable reuse preserves the table identifier, indicator definition, country note and any break in series instead of copying an isolated percentage.[S1]
The statistical annexes are part of the evidence, not supplementary reading. They set definitions, sources, coverage and notes for each table. A sound citation identifies the table and indicator used, the participating population and the reference period. Local completion, progression or employment evidence can then be reconciled with that definition, with differences documented rather than removed through an unsupported conversion.[S1]
Institutional transition evidence can link graduate records to a clearly defined follow-up population while reporting response and matching rates. Employment, further study, unemployment and unknown outcomes remain separate categories. Salary or occupation measures need lawful collection and contextual interpretation. The report also distinguishes a programme's contribution from labour-market conditions and learner characteristics that the provider did not control.[S1]
Relating system context to institutional outcomes
The report primarily covers OECD and partner education systems. Coverage and source year vary by indicator. Institutional benchmarking is defensible only where the provider population, programme level and outcome definition correspond to the published measure.[S1]
The compendium primarily compares participating countries and education systems. Measures may refer to age groups, qualification levels, new entrants, graduates or employed adults, each with a different denominator. An institution serves a narrower population and may operate in a labour market unlike the national average. Programme mix, learner mobility and further study also affect observed transitions.[S1]
Comparability and attribution limits
Cross-sectional associations between education and labour outcomes do not establish the effect of a named programme. International averages can obscure national funding, admissions and labour-market structures. Missing data and provisional figures need to remain visible.[S1]
Employment and earnings outcomes are influenced by economic conditions, field of study, prior attainment and learner characteristics. They are not a direct measure of teaching quality. Completion data can differ by cohort and observation period. A national average may conceal regional or group inequality, while small local cohorts can produce unstable rates that require multi-period interpretation.[S1]
OECD indicators within ICEQC analysis
ICEQC uses the report as external contextual evidence. An OECD average is not an ICEQC benchmark, and no certification decision follows from it alone. The current public ICEQC edition post-dates this article and is not linked retrospectively.
ICEQC may use Education at a Glance to establish comparative context and test the definition of an institutional claim. OECD indicators do not become ICEQC performance thresholds by citation. The historical record neither claims OECD endorsement nor applies a later ICEQC standard.
