Autism has been studied, nowadays, by different fields of knowledge. Far from a certain comprehensive cohesion, its clinical picture is taken as multifactorial. Regarding the processes of inclusion of these students, its effectiveness is still to be built. In this article, we aimed to investigate the perception of teachers about the inclusion of children and adolescents with autism in a regular public school in the metropolitan area of Porto Alegre/RS. To this end, we undertook a qualitative study, with the participation of ten teachers, using two main tools for data production: a sociodemographic questionnaire and a semi-structured interview script. The interviews were recorded and transcribed in full for later analysis using Content Analysis. The results point to the ambivalences inherent to the process, situating the potentials and limitations glimpsed in the school territory. Between bets and unknowns, the participants place the precariousness of training and the low number of teachers as limiting factors for a so-called inclusive education.
