ICCS is an ongoing, comparative research program that investigates the ways in which young people are prepared to undertake their roles as citizens. ICCS reports on levels of students’ civic knowledge, their understanding of concepts and issues related to civics and citizenship, as well as their civic attitudes and engagement. ICCS collects and analyzes a rich array of contextual data from policymakers, teachers, school principals, and the students themselves, about the organization and content of civic and citizenship education (CCE) in the curriculum, teacher qualifications and experiences, school climate, home and community support. Participating in ICCS provides countries reliable information on the crucial learning area of CCE and helps them make informed and data-driven decisions as to their education policy.
