YOUR QUESTION. A CLEARER NEXT STEP.
What an AbilityScore of 400–500 means in cerebral palsy
An AbilityScore of 400–500 is a clinician-administered snapshot of how your child with cerebral palsy currently functions — a baseline to build a personalised plan from, not a ceiling. Its real power is in tracking progress against your child's own earlier score. Only a Pinnacle clinician forms the score and any diagnosis.

When a number lands in front of you, it can feel like a verdict — but for your child with cerebral palsy, an AbilityScore band is a map, not a label.
In short
An AbilityScore® of 400–500 is one band on a structured, clinician-administered profile of how your child currently functions across areas like movement, communication, daily living and learning. It is a snapshot of present support needs, not a ceiling on what your child can become. For a child with cerebral palsy, it tells your clinician where to begin and what to build first — and it is read alongside your child's own history, never in isolation.
What this band is telling you
Think of the AbilityScore® as a starting baseline that turns a broad diagnosis into a personalised plan:
- It describes function, not worth. Cerebral palsy (ICD-11 8D20) affects movement and posture, but every child's profile is different — two children with the same diagnosis can have very different scores and very different strengths.
- It is a baseline to grow from. The real value appears when your child is re-measured against their own earlier score, so progress — a steadier grasp, a clearer word, an easier transfer — becomes visible and trackable.
- It guides the mix of support. The band helps your clinician decide where physiotherapy, occupational therapy, speech and communication work, and family coaching should focus first.
This aligns with how the WHO frames disability through the ICF — as the interaction between a child's body, their activities and their everyday environment — rather than a single fixed number.
The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from an online form or a band number alone. Backed by 2.5 billion+ data points and 25 million+ therapy sessions, our clinicians read your child's band against their own baseline and design a plan around their strengths. Explore physiotherapy and movement support, how the AbilityScore® is calculated, or start where it matters most for your family at Pinnacle.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch how your child's function changes over time, not just the band today — a steadier grasp, easier transfers, a clearer attempt at words. Flag any loss of skills they once had, increasing stiffness or new pain to your clinician promptly.
In everyday life
Pick one everyday goal your child's band points to — say, reaching for a toy or holding a spoon — and build short, playful practice into daily routines. Celebrate every attempt; small repeated wins are how baselines move.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Is an AbilityScore of 400–500 a bad result?
No. The AbilityScore® is not a pass or fail — it describes how your child currently functions across several areas so a clinician can plan support. It is a starting point to grow from, read alongside your child's own history and strengths.
Can my child's AbilityScore improve?
Yes — the most meaningful comparison is against your child's own earlier score. With targeted therapy and family coaching, function in movement, communication and daily living can progress, and re-measurement makes that progress visible.
Does the band tell me my child's diagnosis?
No. A band number is not a diagnosis. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. by a qualified clinician, who interprets it within your child's full picture.
