Treatment foster care is a form of foster care where specifically educated foster parents provide adequate care for children that have behavioral problems. It is a type of foster care that is relatively widespread in the world, and its first major breakthrough was introduced by the development of Multidimensional treatment foster care. Despite the fact that a specialized form of foster care that is also focused, among other things, on adopting children with frequent behavioral problems is mentioned in the Foster Care Act (the Official Gazette of the Republic of Croatia 90/11, 78/12), for now, treatment foster care does not exist in the Republic of Croatia. According to everything mentioned above, the main goal of this paper is to explore the experts’ knowledge about treatment foster care and their opinion about possibilities of its implementation in the Republic of Croatia. By conducting qualitative research, it has been found that the research participants do not know the term “treatment foster care”. However, in their deliberations over an adequate model of treatment foster care, they were very close to already existing programs of treatment foster care and international professional standards for treatment foster care. In addition, the participants’ statements show positive opinion about the existence of the possibility of treatment foster care implementation in the Republic of Croatia and about measures that should be taken during the process. Ultimately, guidelines have been created that would, based on the results of this and other research, help improve the child care system in Croatia, but also develop an adequate model of treatment foster care.
