What a Sensory AbilityScore of 300–400 means for your child

A number is never your child — it is a gentle map of how they take in the world, so we can support them with warmth and precision.

In short

A Sensory AbilityScore in the 300–400 band is one structured snapshot of how your child currently processes sensory information — sounds, textures, movement, light, touch — compared with their own baseline. It suggests your child may be navigating some sensory experiences differently and could benefit from supportive strategies, but it is not a diagnosis and not a verdict on their future. The most useful thing a band does is point a clinician towards where to look more closely and how to help.

What this band is really telling you

The AbilityScore® places your child's sensory profile on a continuous scale so progress can be seen over time. A 300–400 reading typically means a clinician will want to understand your child's sensory world in more detail — gently and without alarm:

• Over-responsiveness — does your child cover their ears at everyday sounds, dislike certain clothing textures, or find busy places overwhelming?
• Under-responsiveness — does your child seem not to notice messes, bumps or being called, or seek very firm input to feel settled?
• Sensory seeking — does your child crave spinning, crashing, deep pressure or constant movement?
• Daily-life impact — how sensory differences affect mealtimes, sleep, dressing, play and time with others.

A band on its own does not explain why — that is the work of a clinician, who reads the number alongside your child's full story. Two children with the same band can need very different support.

How to hold this number

Think of the band as a starting point for a caring conversation, not a label. It helps your clinician tailor an approach — often sensory-informed occupational therapy — and gives you a clear baseline to measure gentle, real progress against. Re-assessment over time matters far more than any single figure.

The Pinnacle way

Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from a number read in isolation. Our AbilityScore® is a clinician-administered structured assessment that measures your child against their own baseline, drawing on 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres.
