The purpose of this paper is to provide an overview of different implementation models of civic education in formal and non-formal educational environment, which was achieved by reviewing the relevant literature and conducting qualitative research. This paper is divided into two main parts. The first part contains a theoretical analysis of civic education and its models of implementation. In this unit, the significance and definition of civic competence and civic education are firstly explained, followed by an overview of the development of civic education in the Republic of Croatia from the 90s of the last century until today. The main part of the theoretical analysis consists of an overview of the implementation models of civic education: in formal educational environment (1. as a cross-curricular topic; 2. as an optional extracurricular activity in elementary schools; 3. as an optional subject in high schools) and in non-formal educational environment (4. through educational activities of civil society organizations). At the end of this unit, an additional model of civic education is described: as a combination of formal and non-formal forms of work - through school volunteering programs. The second part of the paper follows, in which the methodology of the conducted research is presented and the data collected from the research participants is analyzed. The goal of this research is to gain insight into the experiences of implementing different models of civic education in formal and non-formal educational environments in the City of Rijeka, and to learn how the implementation of the same is described by the practitioners themselves. Research questions include: description and explanation of attributes of the model with which implementers are (un)satisfied, description of work methods, description of difficulties they encounter when implementing activities, and description of student engagement in the implementation of a particular model of civic education. For the purpose of data collection, four semi-structured interviews were conducted, and the research was conducted at the beginning of July 2023. Informations obtained through interviews provide guidelines for improving implementation of each individual model of civic education.
