The International Civic and Citizenship Study (ICCS) 2022 continues IEA’s investigation into the ways in which young people understand and are prepared to be citizens in a world where contexts of democracy and civic participation continue to change. This assessment framework provides insight into the study’s conceptual background, cognitive, affective-behavioral and contextual content, and assessment design. It also describes content relevant for the measurement of the United Nations’ Sustainable Development Goals (SDGs) that is related to Global Citizenship Education (GCED) and Education for Sustainable Development (ESD). Countries that participated in ICCS 2009, ICCS 2016, and ICCS 2022 will be able to monitor changes in their students’ civic knowledge, attitudes, and engagement over time.
