What an AbilityScore of 400–500 in Completion Means

An AbilityScore band is not a verdict on your child — it is a gentle starting picture that helps us walk forward together.

In short

An AbilityScore® of 400–500 in Completion means a clinician-administered assessment has placed your child in a particular band for how they finish, follow through and round off tasks — staying with an activity until it is done. A single band is a snapshot of where your child is today, against their own baseline, not a label or a ceiling. What truly matters is the practical plan that flows from it, and that is read and explained only by a qualified clinician who has seen your child.

What "Completion" is looking at

Completion is about your child's ability to stay with a task and bring it to a finish — for example, putting away the last few blocks, finishing a puzzle, or following a short sequence of steps through to the end. A clinician interprets a band like 400–500 alongside many other things:

• Attention and stamina — how long your child can hold focus before the task feels too big.
• Sequencing and working memory — whether your child can hold the steps of a task in mind.
• Motivation and reward — some children stop not because they cannot, but because the activity has lost interest.
• Task difficulty and support — completion grows quickly with the right scaffolding and a task pitched just right.

A mid-range band often means your child is building this skill and benefits from gentle, structured practice — short tasks finished with warm encouragement, gradually lengthened. It is best understood next to your child's other domains, not in isolation.

How to think about the number

Numbers can feel weighty, so hold this band lightly. It is most useful as a direction-setter: it tells your clinician where to begin, what to strengthen, and how to measure progress over time. The same child can move bands as skills, confidence and supports grow — which is exactly why we re-measure.
