The primary school sector, where educational and socialization activities occur, is the first and most important sector for integrating migrant students into a new environment. Nevertheless, the 2019 Migrant Integration Policy Index (MIPEX) for Slovenia concludes that while Slovenian integration policies provide equality on a legal or theoretical level, they do not fully integrate immigrants into society. Therefore, this research has answered the main research question with a methodologically empirical analysis based on semi-structured interviews with teachers or other professionals in selected primary schools. The study examines the integration of immigrant students into Slovenian primary education, specifically within the pedagogical framework. It explores the challenges encountered by pedagogical and professional staff in this context, as well as the experiences of immigrant students and the overall classroom community throughout the educational process, as reported by the interviewees.
