The present work aims at analyzing the process of inclusion of autistic children in two public schools of two municipal districts of Rio de Janeiro lowlands. For this purpose, a bibliographical literature reviewing on autism, educational inclusion and social exclusion was carried out, including field research, where interviews were done with teachers and school directors who work directly with the autistic children, their relatives and classroom colleagues. In spite of the inclusive discourses which permeate the school community and the main documents and legislation, which justifies the pedagogic practices, the educational inclusion of autistic children is still weak and inefficient. The intolerance, distancing and exclusion are present in the majority of the interpersonal relations with autistic individuals and their relatives. It is necessary to reformulate the educational and health public policies so that the inclusion, with the meaning of socialization, learning and development, happen to the great majority of the of schools, and that the students with special educational needs, in particular the autistic ones, have not only the guarantied right of access but also the right of staying at school. The inclusion by force of law does not offer guaranties that the pedagogic practices are in fact inclusive, and one of the central points is the reformulation of the teachers learning for the work with diversity. The relationship between education and health are necessary as the early diagnosis of autism guaranties that the pedagogical interventions offer more favorable results. It is also necessary that the relatives can count on therapeutic care to guarantee a better mental health to properly take care of their children and overcome conflicts and pains related to the autism. Inclusion without the proper teachers training, the support of the colleagues and the participation of the relatives can represent, paradoxically, the worst of the exclusions.
