Picture Exchange Communication System (PECS) is a communication system that relies on pictures to convey items and actions. PECS is often used with individuals with Autism Spectrum Disorder (PECS) and other neurodevelopmental disorders, as children with ASD tend to respond better to visual than verbal material. 

What PECS Look Like

Generally, PECS pictures are very basic, as children with ASD tend to focus on only one aspect of a picture at a time. They can be black and white or color, real pictures or an app on a phone or tablet.

How PECS are Used

With low functioning individuals, PECS can be paired with a verbal instruction for the first prompt. Subsequent prompts can then be directed back to the picture. PECS can be carried on a key ring or in a binder if they are actual pictures. Naturally, having them in an app can make this process easier. The child can be instructed to point to the picture or hand it to the individual with whom they are communicating. For higher functioning individuals, PECS can also be used to create visual schedules or teach a new skill.
