The Picture Exchange Communication System (PECS)

 

 

 

 

 

 

PECS is an evidence-based AAC system in which individuals communicate by exchanging picture symbols to request items, express needs, and convey wants. PECS is taught through structured phases that systematically build expressive communication skills and promote independent communication.

 

 

 

When PECS is appropriate for a student, I start by identifying highly motivating items so communication feels meaningful right away. I teach the student to exchange a picture for a desired item, helping them understand that giving a picture gets them something they want. This builds the foundation that communication is powerful.

 

 

 

 

 

 

 

As the student progresses, I guide them through the PECS phases moving from simple requesting to building short sentence strips like “I want ___” and eventually answering questions or making comments. I tailor the symbols to each student’s needs and work closely with teachers and families to ensure PECS is used consistently throughout the day. My goal is to help the student become a more independent and confident communicator across settings.
