AbilityScore® 500–600 in Gross Motor Delay: what to do next
An AbilityScore® of 500–600 for Gross Motor Delay is a baseline, not a verdict. The next step is to convert it into a personalised physiotherapy plan targeting the next achievable milestone, pair clinic work with daily home play, and re-measure on a schedule against your child's own profile — all reviewed with your Pinnacle clinician.
In this answer 4 sections
An AbilityScore in the 500–600 band is not a verdict — it's a starting line, and you already have it in hand.
In short
Your child's AbilityScore® is a clinician-administered baseline — a snapshot of where your child's gross motor skills are right now, measured against their own profile rather than against other children. A 500–600 band simply tells your therapy team where to begin and what to strengthen first. The next step is straightforward: turn that baseline into a personalised physiotherapy and motor-development plan, and re-measure on a set rhythm so you can see real movement.
What "next" looks like
Gross motor skills — rolling, sitting, crawling, standing, walking, climbing, balance — build on one another like steps. With a baseline already in place, your team will:
- Identify the next achievable milestone rather than chasing the whole staircase at once.
- Set short, concrete goals — for example steadier independent sitting, pulling to stand, or more confident steps — matched to your child's current band.
- Combine clinic sessions with home practice, because the play you do daily is where most progress is built.
- Re-measure on a planned schedule, so the band is compared to your child's own earlier result and quiet gains become visible.
Development moves in spurts and plateaus, so a band is a moment in a journey — not a ceiling. The goal is steady, functional movement that lets your child explore and keep up.
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 alone. Your therapist will review this band with you, explain what it means for your child, and shape a plan around the next milestone. Across 70+ centres, 700+ therapists and 25 million+ therapy sessions, the approach is the same: measure honestly, plan precisely, and celebrate every small win.

Next step — Sit down with your child's therapy team to turn this baseline into a milestone plan. Book a physiotherapy review with a Pinnacle clinician.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch for whether your child is building toward the next motor step — steadier sitting, pulling to stand, more confident steps. Flag to your clinician sooner if your child loses a skill they once had, shows marked stiffness or floppiness, or strongly favours one side of the body.
In everyday life
Make floor play your daily workout: tummy time, reaching for a favourite toy just out of grasp, and cruising along low furniture. Ten unhurried minutes of motivating, supported movement a day builds real strength — and keep it joyful, never forced.

Bring your questions to a first visitQuestions families ask
Is an AbilityScore® of 500–600 a bad result?
No — it isn't a pass or fail. The band is a clinician-administered baseline that simply shows where your child's gross motor skills are now, so your team knows where to begin and can re-measure progress against your child's own profile.
Does this score mean my child has been diagnosed?
No. An AbilityScore® band is not a diagnosis. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under a qualified clinician's care.
How soon should we start therapy?
Once you have a baseline, the most helpful next step is reviewing it with your clinician and beginning a personalised physiotherapy plan promptly — early, motivating practice tends to build gross motor skills most effectively.
How will we know if therapy is working?
In two ways: everyday wins such as steadier sitting or new steps, and objective re-measurement against your child's earlier band on a planned schedule, reviewed with your therapist.
