This paper investigates the role of ethnic majority staff in the perpetuation of monocultural education that excludes non-western, ethnic minority cultures and reproduces institutional racism in schools. Based on qualitative data collected through semi-structured interviews in four ethnically diverse schools in the Flemish educational system, we specifically investigate the role of ethnic majority staff in the reproduction of monocultural school practices through a discursive theoretical lens. The study advances the current literature on institutional racism by showing how situated meanings of monocultural school practices at the micro level of individuals are discursively inter-linked with the macro-level monocultural model of education.
