The main objective of this thesis was to evaluate the communication and sociability indicators of individuals with ASD after 2 years of group treatment in a reference unit for autism spectrum disorder, in the public health service. For this, we use 4 scales that address the most diverse ASD skills. After analysis, significant differences were observed in all applied scales, that is, there was an improvement in the indicators. The survey of information was carried out in a public health service, with several variables involved, such as time to carry out the interviews, structuring of the service for intervention and training of the entire team. Therefore, the scales used in the assessment and reassessment were also chosen to be accessible and low-cost tools for the service profile. New analyzes will be of great importance to continue the results achieved in this thesis.
