Assess quantity comparison through a graded, criterion-referenced hierarchy — from perceptual judgement of clearly unequal sets to close comparisons needing one-to-one correspondence. Document accuracy, prompt level, latency and strategy, then re-probe on a fixed schedule to chart the trajectory against the child's own baseline. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional.

*Quantity comparison — knowing which set holds *more*, *fewer* or *the same* — is an early numeracy foundation, and tracking it well means measuring change against the child's own baseline.*

## In short
Assess quantity comparison through **structured, criterion-referenced observation across a graded hierarchy** — from gross perceptual comparison of clearly unequal sets, to close comparisons requiring one-to-one correspondence or counting. Document accuracy, response latency, prompt level and strategy used, then re-measure on a fixed schedule to chart the trajectory rather than a single snapshot.

## The assessment, in practice
Build a probe set that isolates the skill and exposes where it breaks down:

- **Perceptual stage** — "Which has more?" with large, obvious differences (2 vs 8). Tests pre-numerical magnitude sense.
- **Equal/unequal discrimination** — same vs different sets, controlling for surface area and arrangement to rule out *more space = more* errors.
- **One-to-one correspondence** — close-quantity sets (5 vs 6) that demand matching or counting; note whether the child counts, subitises or guesses.
- **Lexical comprehension** — *more, fewer, less, equal, the same* mapped to action, separating concept from vocabulary.
- **Generalisation** — across materials, modalities and contexts.

Record per trial: **accuracy %, prompt hierarchy level (independent → gestural → verbal → model), latency, and observed strategy**. Track against baseline with repeated brief probes — weekly mastery checks plus a periodic review — so progress is a slope, not a one-off score. Always tell apart a conceptual gap from a language-access or attention barrier.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — never from an online figure. The AbilityScore® is a clinician-administered structured assessment that benchmarks a child against *their own* baseline, drawing on 2.5 billion+ data points and 25 million+ therapy sessions. Pair quantity-comparison probes with targeted [special education](/special-education) and review [quantity comparison](/quantity-comparison) and [what the AbilityScore is and how it's calculated](/ask/what-is-the-abilityscore-and-how-is-it-calculated).
