PECS is short for picture exchange system. It is one of the most common communication interventions used with children with ASD especially those with significant communication impairments. Children with ASD often have difficulty communicating their basic wants and needs. This intervention focuses on giving them a tool (pictures) to communicate. Over time the goal is to use the pictures to exchange for items, build sentences, and answer questions. We have several books on PECS in our library and we can make PECS pictures for you in our resource room.
