What an AbilityScore of 300–400 means in DCD

Seeing a number like 300–400 next to your child's name can feel daunting — but here's what it really tells you, and why it's the start of a hopeful plan, not a verdict.

In short

An AbilityScore® band of 300–400 is one point on your child's own developmental map — a structured, clinician-administered measure of where their motor coordination and related skills sit right now. For a child with [Developmental Coordination Disorder](/) (DCD), this band typically reflects meaningful difficulty with everyday physical tasks — dressing, handwriting, using cutlery, balance or ball skills — that benefits from focused support. It is a starting baseline, not a ceiling, and it is designed to be re-measured as your child grows and gains skills.

What this band actually describes

Think of the AbilityScore® as a precise photograph of one moment, taken so we can compare your child to themselves over time — never to a classroom of other children. In the 300–400 range, a clinician is usually seeing:

• Motor planning and execution that lag behind age expectations — clumsiness, dropping things, or tasks taking longer
• Coordination demands of daily life (buttons, laces, writing, scissors, riding a bike) needing more effort or support
• A clear, workable picture of which specific skills to build first

What the band does not mean: it is not your child's intelligence, their future, or a fixed limit. DCD (ICD-11 6A04) describes a difficulty in acquiring and executing coordinated motor skills — it does not describe a child's potential. With targeted occupational therapy and practice, children move through these bands.

Why we measure this way

A single number in isolation can mislead — development moves in spurts and plateaus. That is why the score is read by a clinician alongside observation, history and your everyday observations, and why it is re-measured. The band tells the therapy team where to begin and gives you a fair, objective way to see progress that everyday life might hide.

The Pinnacle way

An 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 draw on 2.5 billion+ data points and 25 million+ therapy sessions to read your child's AbilityScore® baseline in full context, then build a plan around their strengths. The aim is always the same: a child who moves, plays and learns with more confidence each month.
