Gross-Motor AbilityScore 300–400: What Are the Next Steps?

A score is a starting point, not a verdict — it tells us exactly where to begin helping your child move with more strength and confidence.

In short

A Gross-Motor AbilityScore in the 300–400 band is a structured signal that your child's big-movement skills — sitting, crawling, standing, walking, running, balance and coordination — may be developing more slowly than typical for their age, and would benefit from a closer look and some focused support. This is not a diagnosis and not a reason to panic. The clearest next step is a clinician review at a Pinnacle Blooms Network centre, where a therapist confirms the picture and builds a simple, playful plan. With early, consistent support, gross-motor skills very often strengthen well.

What this band means and your next steps

Gross-motor skills are the foundation for so much — confident movement helps a child explore, play, build core strength, and even supports attention and learning. A 300–400 band simply flags that this area deserves attention now, while your child's growing body and brain are most adaptable.

Your practical next steps:

• Book a clinician review. A physiotherapist or paediatric therapist confirms the AbilityScore® picture in person and looks at how your child moves, not just what they can do.
• Rule out the simple things first. Sometimes slower motor progress relates to muscle tone, low practice opportunity, or a child simply finding their own pace — the assessment helps tell these apart.
• Begin focused, play-based support. If indicated, physiotherapy or occupational therapy builds strength, balance and coordination through movement games your child enjoys.
• Bring movement into everyday play at home. Floor time, climbing, ball play, tummy time for little ones, and lots of safe space to practise all help.
• Track and re-measure. Progress is reviewed over time so the plan adjusts as your child grows.

When to seek a prompt review

Seek a review sooner if your child has lost a skill they previously had, seems very floppy or very stiff, strongly favours one side of the body, or shows no progress over several months. Any sudden loss of movement or strength needs prompt medical attention first.

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 number alone, or an online form. The band is a signpost; a clinician turns it into a precise plan. Understand how the AbilityScore is calculated, explore physiotherapy and gross-motor support, and see how a tailored plan begins at Pinnacle Blooms Network. With 25 million+ therapy sessions and 4.95 lakh+ families served across 70+ centres, your child's next steps are well-charted.
