The presented study focuses on the institutional provision and implementation of citizenship education in selected countries that have a developed concept of citizenship education and address this issue. At the same time, we consider these countries as examples of good practice and inspiration for the Slovak concept of citizenship education of adults, which, from our point of view, is not sufficiently developed. At the same time, it must be emphasized that citizenship education of adults is significantly influenced by the overall socio-cultural development and history of society in each country, which is also the reason why countries differ in their citizenship education of adults’ models. This study is based on the scientific monograph of the authors of the study – Models of citizenship education of adults (source link in the list of bibliographic references).
