Existing research on the education of refugee children has been conducted in countries with a longstanding tradition of refugee integration. The aim of this study was to gain insight into the integration process of refugee children in Croatian schools. Croatia is a small EU country with limited experience in refugee integration. The phenomenological approach was used to examine the experiences and perspectives of the relevant actors. Interviews and focus group discussions were conducted with refugee children (N = 15), their parents (N = 5), classmates (N = 50), and school staff (N = 54) from six elementary schools in Zagreb. Data analyses suggested three general needs: educational, language, and social, each of them connected to more specific needs, challenges, and suggestions. The results of the study are discussed within the Schachner et al. (2017) framework of immigrant adolescents' acculturation.
