This brochure focuses on a selection of indicators from "Education at a Glance," selected for their particular relevance in the current context. Their analysis enables the understanding of countries' response and potential impact from the COVID-19 containment measures. The following topics are discussed: (1) the impact of the crisis on education, including public financing of education in OECD countries and international student mobility; and (2) COVID-19 and educational institutions, including the loss of instructional time delivered in a school setting, measures to continue students' learning during school closure, teachers' preparedness to support digital learning, when and how to reopen schools, class size, a critical parameter for the reopening of schools, and vocational education during the COVID-19 lockdown.
