PECS stands for Picture Exchange Communication System. It is a unique alternative or augmentative communication system. Where its goal is to teach functional communication.

How does it work?

Each individual student learns to exchange a picture of a reinforcer (desired item) to a communicative partner. As the student progresses through each phase, they will begin to learn the discriminate pictures and form sentences for questioning and commenting.

There is evidence that shows that some learners using P.E.C.S. develop speech. As a highly supported Evidence Based Practice (E.B.P.), P.E.C.S. stems from the Pyramid Approach – an effective model for children with developmental disabilities to learn effectively. It is a teaching protocol based on B. F. Skinner‛s book and a broad spectrum of behavior analysis.

The pyramid diagram displays the two types of learning elements – structural and instructional. The base of the Pyramid is made of structural aspects for a productive learning environment. The top of the Pyramid focuses on effective formulation of learning. The Pyramid Approach puts more emphasis on ‘how to teach‛. This makes it possible for each individual student to meet their learning objectives through specific prompting and reinforcement strategies.
