Governments are increasingly looking to international comparisons of education systems as they develop policies to enhance individuals’ social and economic prospects, provide incentives for greater efficiency in schooling, and help to mobilise resources to meet rising demands. The OECD Directorate for Education and Skills contributes to these efforts by developing and analysing quantitative, internationally comparable indicators that it publishes annually in Education at a Glance. Together with OECD policy work, these indicators assist governments in building more effective and equitable education systems. Beyond government officials, Education at a Glance also aims to support researchers with data for further analysis and help the general public understand how their countries’ education systems compare internationally.
