Citizenship education has been implemented in the Croatian educational system since 1999. Today it is an intersubject topic that is realized as obligatory in primary and secondary schools. In order to implement citizenship education in a quality way, it is necessary to train school and teaching staff and parents in order to be competent for transferring knowledge, attitudes and values to students. Accordingly, the aim of the research in this paper was to examine the opinion of teachers from grade 1 to 4 of elementary school and parents of students on citizenship education and correlation with the curricula in question. Special questionnaires were created for the purpose of this research. Research problems were related to the determination of the measure of familiarity of teachers and parents with citizenship education, with its importance and the examination of correlation between curricula and citizenship education. Although the results of the research are good and point to the presence of citizenship education in parents' lives and in schools, it is necessary to create workshops and to raise awareness of parents how much this area offers knowledge, skills and habits for preparing children as future active citizens.
