The purpose of this study was to evaluate the use of peer-mediated instruction for requesting during a snack time routine for children with extensive support needs who were also beginning communicators. Participants included three children aged five with extensive support needs who used a tablet-based augmentative and alternative communication (AAC) to communicate. Using a nonconcurrent multiple baseline design, participants were taught by peers without extensive support needs, to request for a preferred snack using modeling and a three-second time delay until responding reached a mastery criterion of 80-100% across five consecutive trials. Results indicated that all three participants acquired the ability to request from a peer using AAC. Limitations and considerations for future research and practice are discussed.
