Peer-facilitated discrete trial training for children with autism spectrum disorder.

In 2 studies, we evaluated the feasibility and efficacy of peer-mediated, school-based discrete trial training (DTT) for students with autism spectrum disorder (ASD). In the first, 6 typically developing elementary-age students were trained to use DTT procedures to teach target academic skills to 3 students with ASD who had been educated in a self-contained setting. A multiple probe-across-tutors design was applied to evaluate the accuracy with which the tutors implemented the DTT protocol.
