The number of children, both accompanied and unaccompanied, currently crossing international borders in search of humanitarian refuge, has increased significantly in the last few decades of the Twenty-first Century. In Brazil, the presence of Haitian migrant children cannot be ignored, as, in addition to the lack of public policies, they are also victims of racism and xenophobia. Schools face a massive impact of migration, which alters their social structure. Often, the school community is not adequately prepared to cater for these children, as is the case with some schools in the Brazilian municipality of Balneário Camboriú. This research, which is linked to the Postgraduate Program in Education at the University of Vale do Itajaí, initially aims to investigate how Haitian migrant children interact with each other, and with Brazilian children, in two early childhood education schools in Balneário Camboriú. It also intends to investigate, based on the presence of Haitian migrant children, the processes of subjection or transgression of expressions of whiteness as a practice of power and representation of white identity, and to analyze the Municipality’s Curricular Proposal regarding Ethnic-Racial Education. The study is based on the Sociology of Childhood, Racial Studies, and Migration. The research is qualitative and is based on a literature review in two databases. The studies analyzed indicate that one reason for the lack of interest and knowledge about ethnic-racial diversity issues in schools is the existing gap in this theme in both initial and continuing teacher education.
