Is PECS one-on-one or in a group?

PECS begins with one supportive adult beside your child — then gently grows into the busy, social world where real conversations happen.

In short

The Picture Exchange Communication System (PECS) usually starts one-on-one — with two adults gently supporting your child to learn the very first exchange — and then steadily expands into group and everyday settings as your child grows in confidence. So the honest answer is both, in sequence: individual teaching builds the skill, and group and natural situations help it become real, spontaneous communication. The goal is always for your child to use pictures to ask, share and connect with many people, not just one therapist.

How the setting changes as your child learns

• Early phases (one-on-one): When a child is first learning to hand over a picture to get something they want, two adults often help — one as the communication partner and one as a gentle physical prompter behind the child. This focused setting makes the very first exchanges clear and successful.
• Building independence: As your child masters exchanging single pictures, then building short picture sentences, the prompting fades and your child practises with different people in different places.
• Group and natural settings: Later, the same skills are deliberately practised across the day — at snack time, in play, with siblings, peers and family — so communication generalises beyond the therapy table. This is where PECS truly comes alive.
• Parents as partners: Because PECS is meant to work everywhere, you are coached to use the same picture system at home, turning ordinary moments into communication practice.

Think of it as learning to swim: you begin with close one-to-one support in calm water, then move confidently into the busy pool where life actually happens.

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, your child's therapist decides exactly when to begin PECS one-on-one and when to widen it into group and everyday settings, as part of speech and communication therapy. You can explore how we build your child's precise profile in what the AbilityScore® is and how it is formed, and learn more about [how we support your child](/).
