This research examines the role of five educational processes; curriculum, language, religion, culture, history, and geography and teachers, teacher education and teaching methods, on the perception of students of other constitutive people in Bosnia and Herzegovina and if it might have an impact on the longevity of the peace within the state. The importance of this research lays in the fact that BiH has experienced ethnic conflict in recent history which affected education and created ethnic division in the educational system. The aim of this research is to look at if the current educational system in BiH works on mending social cleavages that erupted as an aftermath of the war. By doing abductive qualitative field study and focusing on the educational system known as “two schools under one roof” findings show that all of the five previously mentioned processes carry to bigger or smaller extent threat and risk for social cohesion and peace in the country. Pupils are exposed to teachings filled with bias and prejudice and teachings that emphasize differences between different groups while ignoring similarities that could bring them together. Findings also suggest that the problem of the segregated educational system in BiH will most likely not end in the foreseeable future due to lack of will from teachers, parents, pupils and decision-makers.
