YOUR QUESTION. A CLEARER NEXT STEP.
What an AbilityScore of 400–500 in Mobility means for your child
An AbilityScore band of 400–500 in Mobility is one clinician-administered snapshot of how your child moves now — balance, coordination, strength and getting about — measured against their own baseline. It is a starting point for a plan, not a label or a limit, and what it means for your child is interpreted only by a Pinnacle clinician.

When you see a number for your child's movement, what matters most is what it means for them — gently, in their own story, and never as a verdict.
In short
An AbilityScore® band of 400–500 in Mobility is one clinician-administered read of how your child is moving right now — their balance, coordination, strength and the way they get from place to place — measured against their own developmental baseline. It is a snapshot to guide a plan, not a label or a ceiling. What this band means for your child is interpreted only by a Pinnacle clinician, alongside everything else they observe.
What a Mobility band actually reflects
Mobility, in the AbilityScore® sense, looks at the gross-motor foundations that let your child explore the world — things a clinician watches in play and movement:
- Posture and core stability — how steadily your child sits, stands and holds themselves.
- Balance and coordination — moving smoothly, changing direction, managing uneven ground.
- Strength and stamina — pushing, pulling, climbing, keeping up with play.
- Milestone progression — rolling, crawling, walking, running, jumping — in their sequence and pace.
- Confidence in movement — whether your child moves freely or holds back.
A band is best understood as where to begin, not a grade. Two children in the same band can have very different stories — which is exactly why the number is paired with a clinician's eyes and your everyday observations before any plan is shaped.
How to read the number calmly
Resist comparing the band to another child's, or to an online chart. The real value of an AbilityScore® band is that it gives your clinician and you a shared starting point — so progress is measured against your child's own baseline over time, and support is matched to what will help most. A band is a beginning of a conversation, not its conclusion.
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 figure or a band read in isolation. Our AbilityScore® is a clinician-administered structured assessment, drawing on 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, that turns careful observation into a warm, practical plan. When movement is the focus, our clinicians pair it with occupational therapy and family-guided play. Learn more about Mobility and what the AbilityScore is and how it's calculated, or start at home.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch how your child moves in everyday play — whether they balance, change direction and keep up confidently, or hold back, tire quickly or avoid climbing and running. Note their own progress over weeks rather than comparing to other children, and share what you see with your clinician.
In everyday life
Give your child plenty of safe, unstructured floor and outdoor play — climbing cushions, walking on different surfaces, chasing and jumping games. Movement grows through joyful repetition, so follow their lead and celebrate effort, not just achievement.
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 a Mobility band of 400–500 a diagnosis?
No. It is one clinician-administered snapshot of how your child moves, measured against their own baseline. A band is never a diagnosis or a label — Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care.
Does this band mean my child has a problem?
Not on its own. A band simply tells your clinician where to begin and helps measure progress over time against your child's own starting point. What it means for your child is interpreted only by a Pinnacle clinician alongside everything else they observe.
Can my child's Mobility band change?
Yes. A band is a snapshot of now, not a fixed ceiling. With the right support and everyday movement play, children grow against their own baseline — which is exactly what the AbilityScore® is designed to track over time.
Should I compare my child's band to another child's?
Best not to. The value of the band is measuring your child against their own baseline over time, not against charts or other children. Share what you see at home with your clinician and let them interpret it in context.
