The Miller Function & Participation Scales (M-FUN) is a clinician-administered, play-based developmental assessment used for children aged about 2 years 6 months to 7 years 11 months — the preschool and early-school years. It looks at how a child's fine-motor, gross-motor and visual-motor skills support everyday participation at home, in play and in early classroom tasks. It is not a diagnosis but a way of mapping functional strengths and where support may help.

*Curious which ages the M-FUN is designed for? Here is the simple answer.*

## In short
The **Miller Function & Participation Scales (M-FUN)** is a developmental assessment used for children aged roughly **2 years 6 months to 7 years 11 months** — broadly the preschool and early-school years. It is a clinician-administered, play-based tool that looks at how a child's fine-motor, gross-motor and visual-motor skills support their everyday participation at home, in play and in early classroom tasks. It is not a label — it is a way of understanding a child's functional strengths and where a little support may help.

## What the M-FUN looks at
Rather than testing skills in isolation, the M-FUN watches how a child *uses* movement and coordination to take part in real activities — holding a crayon, managing scissors, copying shapes, building, and moving with control. Because it is designed for the **2½ to nearly 8 years** window, the activities are presented as engaging games, so younger children stay relaxed and motivated. Alongside the hands-on tasks, observations from parents and teachers help build a rounded picture of how a child participates day to day, not just how they perform on a single morning.

## When it is used
An occupational therapist or qualified clinician may choose the M-FUN when there are questions about a child's fine-motor or coordination development, school-readiness, handwriting, or how comfortably a child joins everyday and classroom activities within this age band. The aim is always to map strengths first, then identify where playful, targeted support could help a capable child thrive.

## 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 therapists choose the right structured assessment, such as the [M-FUN](/m-fun), for your child's age and questions, and may pair it with [occupational therapy](/occupational-therapy) to build motor and participation skills through play.
