The International Civic and Citizenship Education Study (ICCS) investigates how young people are prepared to undertake their roles as citizens across a wide range of national contexts, and it is the only international study dedicated to this learning area. ICCS 2022 gathered and analyzed data from representative national samples on students’ conceptual knowledge and understanding of civics and citizenship, as well as their attitudes to, and engagement with, aspects related to civic and citizenship education. Building on previous IEA studies in this field dating back to 1971, and especially since 2009, ICCS 2022 continued to monitor changes in students’ civic knowledge and understanding, patterns of and dispositions toward civic engagement, attitudes to citizenship and equal rights as well as the school and classroom context for learning about citizenship. Furthermore, ICCS 2022 gathered data related to new developments such as increased globalization and migration, the way schools address increasing social diversity, young people’s civic engagement with digital technologies, their views of their political systems, and aspects of globally oriented citizenship. Delivered for the first time on computer in about two thirds of the participating education systems, ICCS 2022 collected a rich set of data using an international student assessment, an international student questionnaire, regional student questionnaires for European and Latin American countries, a teacher questionnaire, a school questionnaire, and a national contexts survey.
