The main goal of this research was to gain insight into how age groups affect the political socialization of final year students in two high schools in Zagreb. This research began with the assumption that young people, depending on the type of high school program, are exposed to different factors of political socialization, and differences in the characteristics of peer groups certainly have an influence on their political culture. In addition to analyzing the differences in the influence of peer groups on political socialization between male and female students depending on the type of high school program, the goal is also to examine differences based on gender. This research was conducted using a qualitative methodology, with in-depth interviews being used as the primary method of data collection. The study involved twenty high school students, equally distributed between a gymnasium and a vocational high school, with each school having an equal number of male and female students. The collected data was analyzed using thematic analysis. This approach allowed for the identification of recurring patterns and themes in the participants' experiences and perceptions regarding political socialization. While this research provides valuable insights, it is important to acknowledge certain limitations. The sample size is relatively small, which may restrict the generalizability of the results. Additionally, the study focused exclusively on two high schools in Zagreb, which may not fully reflect the broader population. The results of this research have implications for educational policy and practice. Understanding the influence of different types of high schools on political socialization can contribute to the development of curricula and additional activities that encourage active participation in civic life among students. This process allows for the customization of the educational experience to meet the needs and interests of young citizens. The findings from this research indicate that there are significant differences in the influence of peer groups on political socialization between male and female students depending on the type of high school, but with regard to gender, the differences are less pronounced or nonexistent.
