What is the Picture Exchange Communication System (PECS)?

When a child has few or no spoken words, a small picture handed over can become their very first sentence — and the start of a real conversation.

In short

The Picture Exchange Communication System (PECS) is a structured, evidence-informed way of teaching a child to communicate by handing over a picture card to ask for something they want or need. It was designed especially for children who are not yet speaking, or whose speech is just emerging — including many autistic children. PECS begins with the most powerful idea in communication: that I can do something to make something happen. Far from holding speech back, it is built to encourage and often grow spoken language alongside it.

How PECS works

PECS is taught in gentle, deliberate stages, always led by the child's own motivation. In the earliest phase, a child learns to pick up a picture of something they love — a favourite snack, a toy, a bubble jar — and place it into an adult's hand in exchange for that item. Because the reward is immediate and meaningful, the child quickly discovers that communication works. From there, the system grows step by step: travelling further to deliver a picture, choosing between several pictures, building a simple sentence on a strip ("I want" + the picture), and eventually commenting on the world around them ("I see", "I hear"). Crucially, the child always initiates — they reach out to you, rather than waiting to be prompted. This is what makes PECS so empowering: it puts the child in the driver's seat of their own voice.

Who it can help, and what to expect

PECS can be a wonderful bridge for children with little or no functional speech, helping reduce the frustration and meltdowns that often come when a child cannot make their needs understood. It is one of several augmentative and alternative communication (AAC) approaches, and a speech-language therapist will judge whether PECS, another picture or device-based system, or a blended approach fits your child best. Parents often worry that pictures will replace talking — but evidence and clinical experience suggest the opposite: giving a child a reliable way to communicate frequently supports, rather than delays, the emergence of speech.

The Pinnacle way

This is general information, not a diagnosis — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our speech therapy team assesses your child's current communication and motivation, then introduces PECS or another suitable AAC pathway as part of an individualised plan — coaching you to use it confidently at home too.
