Speech and language therapy is the broad professional discipline supporting how a child understands, expresses and uses communication, led by a qualified therapist. PECS — the Picture Exchange Communication System — is one specific tool used within that field, where a child exchanges a picture card to request something. They are not alternatives: PECS is one evidence-based method a speech and language therapist may choose, often for pre-verbal or minimally verbal children, as part of a wider individualised plan that aims to support, not replace, spoken language.

*When your child is finding words hard to reach, it helps to know the difference between the whole therapy and one clever tool inside it.*

## In short
**Speech and language therapy (SLT)** is the broad, professional discipline that supports every part of how a child understands, expresses and uses communication — sounds, words, sentences, social interaction, and where needed, alternative ways to communicate. The **Picture Exchange Communication System (PECS)** is *one specific tool* used within that wider field: a structured, step-by-step method where a child hands over a picture card to ask for something they want. So they are not rivals — PECS is one option a speech and language therapist may choose, when it fits the child, as part of a larger therapy plan.

## How they differ — and how they fit together
**Speech and language therapy** is led by a qualified speech and language therapist who assesses the whole communication picture: how your child takes in language (understanding), how they get language out (talking, gestures, or alternative methods), the clarity of their speech sounds, and how they connect socially. From that assessment the therapist builds an individualised plan, which may include play-based language work, speech-sound practice, parent coaching, and — for children who are not yet speaking — augmentative and alternative communication (AAC) methods.

**PECS** sits inside that AAC space. It is a six-phase approach that teaches a child to initiate communication by exchanging a picture for a desired item or activity. It is especially useful for children who are pre-verbal or minimally verbal, because it gives them an immediate, powerful way to be understood — which often reduces frustration. Importantly, PECS is designed to *support* spoken language, not replace it; for many children, picture-based requesting becomes a bridge towards words, not a dead end.

Think of it this way: speech and language therapy is the whole toolkit and the skilled hands using it; PECS is one well-evidenced tool in that kit, chosen when it matches your child's stage and needs.

## When to seek a review
Consider a speech and language review if your child is not babbling or using gestures by around 12 months, has very few or no words by 18–24 months, is not combining words by around 2 years, is hard to understand, becomes very frustrated trying to communicate, or seems not to understand simple instructions. A therapist will decide *whether* a tool like PECS is the right fit — that choice is never made from a leaflet, but from knowing your individual child.

## The Pinnacle way
This is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) 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](/speech-therapy) team assesses your child's whole communication profile first, then chooses the right approach — which may include PECS or other AAC methods — and coaches you to use it at home.

**Next step —** If you are unsure whether your child needs speech and language therapy or a tool like PECS, book a communication screening so a qualified therapist can guide the right next move.
