This study compiles an overview, from international perspectives, of the applicability and relevance of a quality assurance tool. Based on ten country reports, it examines the quality assurance requirements in the field of education for democratic citizenship, and makes a comparison of the specific evaluation systems in those countries. It provides a feasibility study on relevant conditions for implementing the tool, and aims to serve as a resource of orientation for policymakers, a case study on implementation for researchers, and source book for the reflection of education practitioners. This publication was developed by the Council of Europe in co-operation with the German Institute for International Educational Research (DIPF) and the Foundation “Remembrance, Responsibility and Future”.
