Abstract: The Picture Exchange Communication System (PECS) is a popular augmentative and alternative communication strategy. Like many communication interventions, the successful use of PECS is dependent on the skills of the communication partner. This article provides a systematic review of the published research on teaching education professionals (EPs) to use PECS. Training of EPs was usually conducted during individual or small group sessions and included a description of the PECS strategy, practice on implementation of PECS, and feedback on performance. Instructional activities typically resulted in an immediate increase in the quality and/or quantity of PECS opportunities provided by the EP; however, mixed findings are reported for maintenance and generalization. Implications for future research and practice are discussed.
