What is PECS?

Picture Exchange Communication System

Developed by: Andrew S. Bondy, Ph.D. & Lori Frost, M.S., CCC/SLP

PECS was developed in 1985 as a unique augmentative/alternative communication intervention package for individuals with autism spectrum disorder and related developmental disabilities. First used at the Delaware Autistic Program, PECS has received worldwide recognition for focusing on the initiation component of communication. PECS does not require complex or expensive materials. It was created with families, educators, and resident care providers in mind, so is readily used in a range of settings.

PECS begins by teaching an individual to give a picture of a desired item to a “communicative partner?, who immediately honors the exchange as a request. The system goes on to teach discrimination of pictures and how to put them together in sentences. In the more advanced phases, individuals are taught to answer questions and to comment.

Here is a video of Michael from Yellow Class using his PECS folder.  He is 'travelling' to his communication partner:
