Physical Development AbilityScore 500–600: Next Steps

A score in the 500–600 band is a clear starting point — and the first step is simply understanding what it means for your child's movement journey.

In short

A Physical Development AbilityScore® in the 500–600 band suggests your child's motor skills — how they sit, crawl, walk, balance, grip and coordinate — may be developing at a different pace, and benefit from a closer look and gentle, targeted support. This is a signpost, not a label or a diagnosis. The right next step is a clinician-led review to understand why the score sits where it does, followed by a tailored plan that helps your child build strength, coordination and confidence at their own pace.

What the next steps look like

• Confirm the picture with a clinician. The number alone never tells the whole story. A qualified Pinnacle clinician reviews how your child moves — gross-motor skills like rolling, sitting, walking and balance, and fine-motor skills like grasping and hand use — alongside their age, history and everyday context.
• Find the why. Some children need help with core strength, some with coordination or motor planning, some with low or high muscle tone. The plan is shaped by the reason behind the score, not the score itself.
• Begin targeted, playful support. Depending on the findings, this may include physiotherapy or occupational therapy that builds skills through play — climbing, balancing, drawing, threading — so practice feels like fun, not work.
• Re-measure and track progress. The AbilityScore® is designed to be repeated, so you and your clinician can see movement skills growing over time and adjust the plan as your child changes.
• Practise at home. Small, daily movement opportunities — tummy time for babies, obstacle play, drawing and building for older children — turn everyday moments into gentle practice.

When to seek a check sooner

Review promptly if your child has lost a motor skill they once had, shows marked stiffness or floppiness, strongly favours one side of the body, or if movement causes pain or distress. These need timely medical review rather than waiting.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app, a form or a number alone. Backed by 2.5 billion+ data points and 25 million+ therapy sessions, our clinician-administered structured assessment turns a band like 500–600 into a precise, personalised plan. From there, support may flow through our occupational therapy for movement, coordination and daily skills. You can explore all our developmental support here.
