The International Civic and Citizenship Education Study (ICCS) included regional modules for Europe, Latin America, and Asia. Thirty-five of the 38 countries that participated in ICCS opted to be involved in these regional modules. Twenty-four countries participated in the European module, six in the Latin American module, and five countries in the Asian module. Regional instruments were developed for each module and were administered to students after they had completed the international assessment. These instruments were designed to address aspects of civic and citizenship education specific to each region. The results of these additional data collections are reported in a series of regional reports. This chapter describes the development of the three regional-module instruments, namely: The European regional instrument: this consisted of a 12-minute cognitive test and a 17-minute region-specific questionnaire (29 minutes total); the Latin American regional instrument: this consisted of a 15-minute cognitive test and a 15-minute region-specific questionnaire (30 minutes total); and the Asian regional instrument: this comprised a 15-minute region-specific questionnaire.
