This was a single-case study which evaluated the effects of PEAK-T on two children with Autism. A total of 6 programs were trained between the two participants using a Multiple Baseline Design across skills. This evaluation was conducted using the subtest materials provided in the PEAK-T modules and through full assessments. The assessments were used to identify the appropriate skill level of each participant and they were used to evaluate whether the skills were maintained. The participants had no prior exposure to any of the PEAK-T programs as demonstrated by the participants baseline scores. The results of the study showed that programming of multiple exemplars resulted in acquisition of novel skills in both participants and that the skills were maintained. Both Participants demonstrated mastery of their programs and a total of 4 programs between two participants were added to the participants repertoire.
