The study evaluated the effectiveness of an in situ behavioral skills training program for training 3 direct care staff to implement the Promoting the Emergence of Advanced Knowledge Relational Training System (PEAK) with 3 individuals with autism.

The data suggest that behavioral skills training improved staff implementation of PEAK and resulted in a corresponding improvement in selected language skills across 2 of 3 learners with autism.
