the Picture Exchange Communication System (PECS)
How PECS Helps a Child with Autism Spectrum
PECS helps a child on the autism spectrum communicate by teaching them to hand a picture card to another person to request or comment, building genuine two-way communication before spoken words arrive. Taught in structured phases, it reduces frustration, encourages the child to initiate, and often supports — not delays — spoken language. A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care.
When words feel out of reach, a single picture handed to you can become a child's first true 'I want to talk to you' — and that changes everything.
In short
The Picture Exchange Communication System (PECS) helps a child on the autism spectrum communicate by teaching them to hand a picture card to another person to make a request or comment — so they can express needs before spoken words arrive. It builds the most powerful early lesson of all: that communication is a two-way exchange that gets a real response. Far from holding speech back, research shows PECS often supports the development of spoken language while reducing the frustration behind many meltdowns.How PECS helps your child
PECS is taught in structured phases, each building on the last:- Phase 1 — the exchange itself. Your child learns to pick up a picture of something they want and place it in an adult's hand to receive it. The breakthrough here is intent — understanding that their action makes a communication partner respond.
- Phase 2 — persistence and distance. Your child learns to seek out their picture book and travel to a person to communicate, even across a room.
- Phase 3 — choosing. They discriminate between pictures, selecting the right symbol for what they actually want.
- Phases 4–6 — building sentences. Using a sentence strip ("I want… biscuit"), then adding describing words, and finally commenting ("I see… dog"), not just requesting.
The deeper benefits parents notice: less frustration and fewer meltdowns because the child finally has a way to be understood; more initiation, because PECS teaches the child to start the interaction rather than only respond; and for many children, a bridge towards spoken words, as the picture and the spoken model are paired at every step. PECS does not replace speech — it gives communication a reliable home while speech is still developing.
When to consider it
PECS suits children who understand more than they can say, who have few or no spoken words, or who become distressed when they cannot make needs known. It works best when guided by a speech and language therapist who tailors the vocabulary to your child's motivators and coaches the whole family to use it consistently across home, therapy and school.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an app or online form. From there, a therapist decides whether PECS, another communication system, or a blend best fits your child, and shapes it around their interests through our speech and language therapy support. You can learn how your child's profile is mapped in our clinician-administered AbilityScore® assessment, and explore more about [how we support communication and development](/) across 70+ centres.Trusted sources

What to watch
Watch whether your child has a reliable way to ask for what they want — children who understand more than they can say, have few spoken words, or become distressed when unable to communicate often benefit most from a picture-based system guided by a therapist.
Try this at home
Place a picture of a favourite snack just out of reach and wait — when your child gives you the picture, respond instantly and warmly with the item and the spoken word, so they learn that one exchange brings a real result.

Frequently asked
Will using PECS stop my child from learning to talk?
No — this is a common worry, but the opposite tends to be true. PECS pairs a spoken word with every picture exchange, and research shows it often supports the development of speech rather than holding it back. It gives your child a reliable way to communicate while spoken language is still emerging.
At what age can PECS be started?
PECS can be introduced in early childhood, often from the toddler years onward, whenever a child has few or no spoken words but shows clear wants and interests. A speech and language therapist will judge readiness and tailor the starting vocabulary to your child.
Do we need special equipment for PECS?
PECS uses simple picture cards and a communication book or board — no expensive technology is required to begin. Your therapist will help you build a personalised set of pictures around your child's favourite things and coach the family to use it consistently.
