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.\n\n## The assessment, in practice\nBuild a probe set that isolates the skill and exposes where it breaks down:\n\n- **Perceptual stage** — \"Which has more?\" with large, obvious differences (2 vs 8). Tests pre-numerical magnitude sense.\n- **Equal/unequal discrimination** — same vs different sets, controlling for surface area and arrangement to rule out *more space = more* errors.\n- **One-to-one correspondence** — close-quantity sets (5 vs 6) that demand matching or counting; note whether the child counts, subitises or guesses.\n- **Lexical comprehension** — *more, fewer, less, equal, the same* mapped to action, separating concept from vocabulary.\n- **Generalisation** — across materials, modalities and contexts.\n\nRecord 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.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — never from an online figure.
