The Picture Exchange Communication System (PECS) is an evidence-based communication tool designed to help individuals with limited or no verbal ability express their needs and thoughts using pictures. It is especially effective for children with autism spectrum disorder (ASD), developmental delays, or speech and language impairments.
PECS works by teaching the individual to exchange a picture of a desired item or activity with a communication partner, such as a parent, teacher, or therapist, in return for that item. This system promotes functional communication and helps reduce frustration related to communication challenges.
PECS is taught in phases, beginning with simple exchanges and gradually progressing to more complex language use, such as forming full sentences or answering questions. The program is highly structured and focuses on motivating the learner by using preferred items and consistent reinforcement.
Unlike some other systems, PECS does not require prior speech or imitation skills, making it accessible to many nonverbal learners. It can be used alongside other communication methods and is often implemented by speech-language pathologists, educators, and ABA therapists.
By giving individuals a voice through visuals, PECS supports independence, social interaction, and participation in daily activities—opening the door to more meaningful communication and connection.
