The aim of this study was to identify variations from different language therapy processes times in two groups of children with autistic spectrum disorders. 8 subjects, from 3 to 17 years old, participated of this study and they were divided in two groups: Group 1: 4 subjects, in language therapy for 12 months, with therapist change after 6 months; Group 2: 4 subjects, also in language therapy for 12 months, but without therapist change in this period. Data was collected from two videotapes recordings: initial and final and all the recordings had fifteen minutes of duration. The analysis was done according to the criteria proposed by Fernandes (2004a), for functional evaluation of language and the statistical analysis were done with the Wilcoxon signed ranks test and the Mann-Whitney test, with 5% of significance. The results showed no difference between the two groups. This outcome may be related to the small size of the groups or to the duration of the study. Nevertheless, a better functional profile of communication was noted on group 2, witch had no therapist change. This outcome was represented by the improving of the communicational acts and the use of the communicative space, it was also noted an increasing of the utilization of the verbal mean and decreasing of the vocal mean, besides a greater utilization of the more interactive functions.
