The research presented in this article focuses on the main challenge facing educational systems around the world: making their schools serve the entire population, removing the barriers that currently prevent it. Despite the fact that inclusive education has occupied a fundamental place on the international political agenda, there are so many challenges to face. This paper will show some contributions and challenges arising from the last 6 years promoting inclusive education in Latin America through different Collaborative Action Research processes. Some of them have focused on teams of teachers developing projects for their own schools, and some of them were dialogic processes with the broader educational communities in different countries and the entire region, offering participatory diagnosis where locate local projects.
