Education at a Glance is the authoritative source for information on the state of education around the world. It provides data on the structure, finances and performance of education systems across OECD countries and a number of partner economies. More than 100 charts and tables in this publication – as well as links to much more available on the educational database – provide key information on the output of educational institutions; the impact of learning across countries; access, participation and progression in education; the financial resources invested in education; and teachers, the learning environment and the organisation of schools.

The 2021 edition includes a focus on equity, investigating how progress through education and the associated learning and labour market outcomes are impacted by dimensions such as gender, socio-economic status, country of birth and regional location. A specific chapter is dedicated to Target 4.5 of the Sustainable Development Goal 4 on equity in education, providing an assessment of where OECD and partner countries stand in providing equal access to quality education at all levels. Two new indicators on the mechanisms and formulas used to allocate public funding to schools and on teacher attrition rate complement this year's edition.
