Miller Function & Participation Scales
Should my child have an M-FUN assessment?
The M-FUN is a play-based assessment for children about 2.5 to 7 years that examines how fine motor, gross motor and visual-motor skills work in everyday tasks, plus how a child participates at home and in the classroom. Consider it if you've noticed difficulties with hand skills, coordination or keeping up in play. It is one clinician-administered tool, not a diagnosis, and the right starting point is a general developmental check at a Pinnacle centre.
If you're wondering whether your child's everyday wobbles — gripping a pencil, climbing stairs, joining in play — deserve a closer look, the M-FUN is one gentle, structured way to find out.
In short
The Miller Function & Participation Scales (M-FUN) is a play-based assessment for children roughly 2.5 to 7 years that looks at how well your child's motor skills — fine motor, gross motor and visual-motor — actually work in real, everyday tasks like drawing, cutting, balancing and joining classroom activities. It's worth considering if you've noticed your child struggling with hand skills, coordination or keeping up physically with peers. It is one clinician-administered tool, never a diagnosis on its own.What an M-FUN involves
The M-FUN is designed to feel like play, not a test — which is exactly why children engage with it so well. A qualified clinician (usually an occupational therapist) guides your child through enjoyable activities while observing how their body and hands are working:- Fine motor & visual-motor tasks — drawing, tracing, using scissors, threading and manipulating small objects, showing how hands and eyes work together.
- Gross motor tasks — balance, jumping, hopping and whole-body coordination that underpin moving confidently through a busy day.
- Participation, not just performance — uniquely, the M-FUN includes home and classroom checklists, so the picture reflects how your child manages in real settings, not only in the assessment room.
The aim is to understand where your child is strong and where a little support would help them participate more fully in play, self-care and early learning.
Should your child have one?
An M-FUN can be helpful if your child tires quickly with hand tasks, avoids drawing or building, seems clumsy or accident-prone, struggles with buttons or cutlery, or finds it hard to keep pace with peers in active play. It is a consideration, not an alarm — many children simply develop these skills at their own rhythm. The right starting point is a general developmental check, where a clinician decides whether the M-FUN, another tool, or simply watchful monitoring fits your child best.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from an online figure or a form. Our clinicians choose the right tool for your child and translate findings into a practical, re-measurable plan: see how our occupational therapy supports motor and participation skills, and read what the AbilityScore is and how it's calculated. Backed by 2.5 billion+ data points, 25 million+ therapy sessions and 700+ therapists across 70+ centres, we make small motor gains visible and usable at home and school.Trusted sources

What to watch
Watch for difficulty with pencil grip, drawing or cutting, frequent clumsiness or falls, trouble with buttons, zips and cutlery, tiring quickly during hand tasks, or struggling to keep up with peers in active play. If these persist or affect everyday participation, ask a clinician whether an M-FUN or other assessment would help.
Try this at home
Build little motor moments into play each day: threading beads, squeezing playdough, tearing paper, hopping games and helping with simple dressing. These strengthen hand and body skills naturally — and let you notice, gently, where your child finds things harder.

Frequently asked
What age is the M-FUN for?
The Miller Function & Participation Scales are designed for children roughly 2.5 to 7 years old. A Pinnacle clinician will confirm whether your child's age and needs make it the right tool, or whether another approach fits better.
Will the M-FUN feel like a stressful test for my child?
No — it is built around playful, engaging activities like drawing, cutting, balancing and jumping, guided by a clinician. Most children experience it as fun rather than a formal test.
Does an M-FUN give my child a diagnosis?
No. The M-FUN is one structured tool that helps a clinician understand motor and participation skills. Any diagnosis or clinical AbilityScore® is formed only at a Pinnacle Blooms Network centre under qualified clinician care.
What makes the M-FUN different from other motor tests?
It uniquely includes home and classroom checklists, so it reflects how your child participates in real daily settings — not just performance in the assessment room.
