"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 accession and partner countries. 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 2023 edition includes a focus on vocational education and training (VET), examining participation in VET and the structure of VET programmes. This edition also includes a new chapter - Ensuring continued learning for Ukrainian refugees--which presents the results of an OECD 2023 survey that collected data on measures taken by OECD countries to integrate Ukrainian refugees into their education systems.
