In the last few years, Chilean educational policies have emphasized the participation of indigenous communities in intercultural preschools. However, recent research has shown that the alliances between indigenous communities and these preschools are still weak. Thus, we focus on the perspective of Mapuche organizations -- in Chile -- regarding the limitations and possibilities for collaboration between their organizations and intercultural preschools. Using a qualitative methodology, we asked: What are the opinions of Mapuche organizations regarding preschools? What kind of cooperation is possible between Mapuche organizations and preschools? And what collaborations are possible between organizations and preschools? From an Indigenous Standpoint and cultural interface perspective, the results show that in order to forge collaborative alliances, the preschools should make profound changes (e.g., hierarchies, solid relationships, critical interculturalism, Mapuche preschools, indigenous knowledge). Finally, the indications put forward in educational policies should go hand-in-hand with concrete measures and resources in the preschool system.
