What an AbilityScore of 400–500 in Jumping means

A number on a page is never the whole child — it's a gentle marker that helps us walk beside your little one's growing legs.

In short

An AbilityScore® band of 400–500 in Jumping describes where your child currently sits on their gross-motor journey for this one skill — it is a snapshot of progress, not a verdict. It tells your Pinnacle clinician how your child's two-footed jumping, take-off, landing and balance compare against their own developmental baseline, so support can be tuned precisely. What truly matters is the pattern over time and how it fits with your child's wider movement, play and confidence — and only a clinician can interpret that fully.

What this band is telling you

Jumping is a lovely milestone because it asks several systems to work together at once — leg strength, balance, body awareness, timing and the courage to leave the ground. A mid-range band like 400–500 usually means your child is building and consolidating this skill rather than at the very start or fully mastered. In practice your clinician will look at:

• Take-off — can both feet leave the ground together, or does one foot lead?
• Landing — soft, balanced landings versus stumbles or sitting down.
• Control and confidence — willingness to jump off a low step, over a line, or with rhythm.
• The wider picture — how jumping sits alongside running, climbing, stairs and overall core strength.

A band is most meaningful when read with your child's age, their other motor skills, and how they're developing month to month — never as a single label in isolation.

When to seek a closer look

This band is reassuring as part of a steady upward trend. It's worth a gentle professional review if your child seems to be plateauing, avoids jumping or active play, tires very quickly, or if gross-motor skills feel out of step with the rest of their development. Early, playful support builds strength and confidence beautifully — and it's far easier to nurture a skill that's already emerging.

The Pinnacle way
