Education at a Glance is the authoritative source for data on the state of education around the world. It provides information on the structure, finances and performance of education systems across OECD countries and partner economies. More than 100 charts and tables in this publication – as well as much more data available online – 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 2022 edition focuses on tertiary education, looking at the rise of tertiary attainment and the associated benefits for individuals and for societies. It also considers the costs of tertiary education and how spending on education is divided across levels of government and between the state and individuals. A specific chapter is dedicated to the COVID crisis and the shift from crisis management to recovery. Two new indicators on professional development for teachers and school heads and on the profile of academic staff complement this year's edition.
