Developed in 1985 by Andy Bondy, PHD and Lori Frost, MS, Picture Exchange Communication System (PECS) allows individuals with little or no communication the ability to do so using pictures. The approach includes a person giving them a picture in exchange of an item. PECS teaches functional communication and includes 6 phases.
- How to communicate. In the first phase, the individual learns to exchange a single picture for an item or activity they want.
- Distance and persistence. The individual learns to generalize by using the picture with different people.
- Picture discrimination. The individual learns to select from two or more pictures to ask for something.
- Sentence structure. Individuals learn to construct simple sentences on a detachable sentence strip
- Responsive requesting. Individuals use PECS to answer wh questions.
- Commenting. individuals are taught to comment in response to questions.
