PECS is designed to teach functional communication with an initial focus on spontaneity. It has been and continues to be implemented in a variety of settings (home, school, community) so users have the skills to communicate their wants and needs. PECS begins with teaching a student to exchange a picture of a desired item with a teacher/communicative partner, who immediately honors the request. After the student learns to spontaneously request for a desired item, the system goes on to teach discrimination among symbols and then how to construct a simple sentence. In the most advanced phases, individuals are taught to respond to questions and to comment. PECS is usually to be combined with elements of behavior analysis.
