The Preschool Language Scales, 5th Edition (PLS-5) is a clinician-administered, play-based assessment of early language for children from birth to about 7 years 11 months. It measures two sides of communication: Auditory Comprehension (understanding language) and Expressive Communication (using words and sentences), which together give a Total Language picture. It is one tool among several and is most meaningful when read alongside a child's history, play and everyday communication — never as a label on its own.

*A gentle, play-based way to understand how well a young child grasps words and uses them — that is what the PLS-5 sets out to capture.*

## In short
The **Preschool Language Scales, 5th Edition (PLS-5)** is a widely used, clinician-administered assessment of early language for children from birth up to around 7 years 11 months. It looks at two sides of communication together — **Auditory Comprehension** (how well a child understands language) and **Expressive Communication** (how well a child uses words, gestures and sentences). It is delivered through warm, play-based and picture activities, so it feels natural to the child while giving the clinician a clear, structured picture of where language is flowing well and where a little support may help.

## What the PLS-5 assesses
The PLS-5 is built around two core scales that, combined, give a Total Language picture:

- **Auditory Comprehension** — how a child takes in and understands language: attending to sounds and speech, recognising words, following instructions, and grasping concepts such as size, number, time and grammar as they grow.
- **Expressive Communication** — how a child gets their meaning across: early sounds and babble, first words and gestures, vocabulary, sentence-building and storytelling as they mature.

Because it spans from infancy through the early school years, the activities shift with age — from observing how a baby responds to voices and play, to picture-based tasks and conversation for older preschoolers. The PLS-5 is one tool among several a speech-language clinician may use; it is most meaningful when read alongside a child's history, play, hearing and everyday communication, not in isolation. A single test never defines a child — it simply helps a clinician understand strengths and next steps.

## When it may be used
A speech-language clinician may draw on the PLS-5 when there are questions about a child's understanding or talking — for example late first words, difficulty following instructions, or limited sentences compared with peers. Noticing a difference early is an invitation to support, not a label, and many early-language gaps respond beautifully to the right, playful help.

## 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. Where a tool such as the [PLS-5](/pls-5) is helpful, our clinicians use it within a fuller picture of your child's communication, then shape an individualised plan that may include [speech therapy](/speech-therapy) and other supports.

## Trusted sources
The American Speech-Language-Hearing Association (ASHA) on assessing early language and communication; the CDC and HealthyChildren guidance on communication milestones in young children; WHO resources on early child development.

**Next step —** If you have questions about how your child understands or uses words, book a developmental review so a clinician can choose the right assessment and map a supportive plan.
