Pyramid Educational Consultants, Inc. is the developer of the Picture Exchange Communication System (PECS) and the Pyramid Approach to Education.
The Picture Exchange Communication System (PECS) was developed in 1985 as a unique augmentative/alternative communication intervention package for individuals with autism spectrum disorder and related developmental disabilities. PECS does not require complex or expensive materials and 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.
PECS has been successful with individuals of all ages demonstrating a variety of communicative, cognitive and physical difficulties. Some learners using PECS also develop speech. Others may transition to a voice output system. The body of research supporting the effectiveness of PECS continues to expand, with research from countries around the world.
