Direct answer
PECS (Picture Exchange Communication System) is a structured communication training protocol developed by Andy Bondy and Lori Frost at Pyramid Educational Consultants. Children learn to communicate by physically exchanging picture cards with a communication partner. The system progresses through 6 defined phases. PECS is widely used in Ontario schools and is OAP-eligible when delivered by an SLP as part of a funded Core Clinical Services plan.
Start with the short answer, then reveal deeper context where helpful.
PECS teaches communication through physical picture exchanges. The physical exchange is intentional — children learn that communication is a two-way social act with real outcomes.
PECS is commonly implemented in Ontario schools by SLP and EA teams. It is considered standard practice for minimally verbal autistic students. To request: (1) ask the IEP team to include PECS as a communication support, (2) request a referral to the school board SLP for assessment and implementation planning, (3) ask that all staff working with your child receive PECS training, (4) request a home communication binder so PECS generalizes outside school.

Phase 1 — The physical exchange. Child picks up a single picture and gives it to a partner to receive a desired item. Physical prompt fades over trials.
Phase 2 — Distance and persistence. Child learns to seek out a partner across distance, travel to them, and complete the exchange.
Phase 3 — Picture discrimination. Child selects from multiple pictures to request the specific desired item.
Phase 4 — Sentence structure. Child builds a sentence strip: "I want ___". Introduces carrier phrases.
Phase 5 — Responsive requesting. Child responds to "What do you want?" with an appropriate picture sentence.
Phase 6 — Commenting. Child learns to comment ("I see ___", "I hear ___") — expanding to social communication.
Each phase must be mastered before moving to the next. Skipping phases undermines the system.

For OAP-funded services: SLP-facilitated PECS is eligible within Core Clinical Services. With 67,509 children waiting, PECS through school is often the fastest route while families wait for funded OAP services.
