International comparative studies on civic education are especially difficult because of the lack of a common understanding of what civic education is as a subject and because of different cultural and political traditions or different school systems. Using the concept of democratic competencies, this paper starts by exploring a theory of authoritarian personalities and operationalising 11 items for an empirical study. Thereby this paper investigates to what extent central topics of civic education are more determined by cognitive factors or personality factors. It shows that matureness is developed not only by political knowledge but also by those democratic competencies which are an essential part of any democratic school and teaching culture.
