ABSTRACT Objective: to describe the communication skills of children with autistic spectrum disorder (ASD), considering the clinical and family perspective. Methods: from the point of view of parents and therapists, the language of ten children with ASD was analyzed. All children underwent speech therapy at the outpatient clinic of a Speech Therapy School. Two protocols were used for data collection. Autism Treatment Evaluation Checklist (ATEC), which was applied to the children's parents, and Protocol for Assessment of Pragmatic Skills of Children with Autism Spectrum Disorders - called Pragmatic Protocol (PP), which was answered by therapists. The data were examined through a descriptive statistical analysis, considering absolute and relative frequency, and inferential statistics, through the Chi-square test, with a 5% of significance for all analyses. Results: an expressive presence of communicative deficits, in the answers presented by the therapists, was seen. In the protocol answered by the parents, it was also possible to observe the same trend, since the children failed to score in several items of Subscale I. Conclusion: parents and therapists evidenced changes in the communicative skills of the children surveyed, and emphasized that therapists, who have technical linguistic knowledge, like parents, can also be good informants about their children's communicative development process.
