This article presents the Picture Exchange Communication System (PECS) and its applications in physical education. The PECS is an appropriate communication intervention for students with autism who lack functional communication skills. It is often confused with other visual support strategies, so the authors delineate the six phases of PECS and illustrate each phase within the physical education environment. This article also provides recommendations for implementing PECS in physical education. (Contains 1 table and 7 figures.)
