In the last decades, Chile has become a receiving society of migrants, and this has overtaxed the social services in this country, among them the school system. According to the literature, the issue is that migration has not been addressed with a proper response from public policies. This article aims to examine recommendations for the development of these policies. To undertake this task, we have conducted a systematic review of the literature on this issue in Chile, Argentina, and Spain (1990–2018). The three cases show the presence of discrimination and racism, with a common response taking the form of intercultural education. In terms of differences, only in Spain there is a consolidated body of research and public policies that focus on migration. That said, although the policies are more robust in Spain, several studies critically assess them. Hence, this country is a good example to know what to do and what to avoid. That information is exactly what is needed in countries like Chile where migration has become pressing issue that demands a proper response.
