YOUR QUESTION. A CLEARER NEXT STEP.
What an AbilityScore of 100–200 in Gross Motor means
An AbilityScore of 100–200 in Gross Motor is a lower band suggesting your child's larger body movements — sitting, crawling, walking, balance — may be developing more slowly than typical for their age. It is a starting point for support, not a diagnosis, and what it truly means is understood only by a qualified Pinnacle clinician alongside your child's full story.

An AbilityScore band is not a verdict on your child — it is a gentle starting picture of where their movement skills are today, and where they can grow.
In short
An AbilityScore® band of 100–200 in Gross Motor is one of the lower bands on our scale, suggesting your child's larger body movements — sitting, crawling, walking, running, climbing, balance — may currently be developing more slowly than the typical pace for their age. It is a starting point, not a label: it tells your clinician where to focus support so your child can build strength, coordination and confidence. A band on its own never diagnoses anything — what it means for your child is understood only alongside their full story, observed by a qualified Pinnacle clinician.
What this band is actually telling you
Gross motor skills (ICF d455, moving around) are the big, whole-body movements your child uses to explore the world. A 100–200 band points your clinician towards a closer, kinder look at things like:
- Core strength and posture — how steadily your child sits, holds their head, or stands.
- Milestone pacing — whether rolling, crawling, pulling to stand, walking or jumping are emerging in their own time.
- Balance and coordination — how confidently your child moves, climbs stairs, or catches themselves.
- Muscle tone and stamina — whether movement seems to take extra effort or tires them quickly.
Importantly, this band reads your child against their own developmental picture — not as a pass or fail. Many children in this band simply need focused, playful practice and the right support to find their stride. The band shows the starting line, not the finish.
What you can do now
Gross motor growth thrives on movement and play. Floor time, climbing, push-along toys and plenty of safe space to move all build the very muscles this band is highlighting. If your child seems to be missing several movement milestones, tires unusually easily, or moves in a way that worries you, a gentle professional look now is the most loving next step — early support is powerful while young muscles and brains are so adaptable.
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 alone or an online figure. Our AbilityScore® is a clinician-administered structured assessment that turns careful observation into a warm, practical plan tailored to your child. Backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, our clinicians pair this with hands-on occupational therapy and movement-building support. Learn more on our home page and read what the AbilityScore is and how it's calculated.

Next step — Turn this number into a plan. Book an AbilityScore assessment with a Pinnacle clinician for a calm, caring read of your child's movement skills and the right way forward.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Seek a professional look if your child is missing several movement milestones (rolling, sitting, crawling, walking) for their age, tires unusually quickly during play, has floppy or stiff posture, or moves in a way that consistently worries you.
In everyday life
Give your child plenty of safe floor and play time every day — climbing, crawling, pushing toys and reaching for things. Repeated, joyful movement is exactly how the muscles and balance this band highlights grow stronger.
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 100–200 Gross Motor band a diagnosis?
No. It is one of the lower bands on our scale and simply points your clinician towards where to focus movement support. A diagnosis is never formed from a band alone — only a qualified Pinnacle clinician, looking at your child's full picture, can say what it means.
Can my child's Gross Motor score improve?
Yes. Gross motor skills are highly responsive to focused, playful practice, especially in early childhood when young muscles and brains are so adaptable. The band shows a starting line, and with the right support many children make strong, steady progress.
What does Gross Motor actually cover?
It covers your child's larger, whole-body movements — sitting, crawling, walking, running, climbing, balance and coordination — the skills they use to explore and move through the world.
