Progress is tracked by re-measuring against the child's own baseline at structured intervals, scoring growth in lexical diversity, word-finding accuracy and comprehension breadth rather than against age norms alone.\n\n## The science of measuring vocabulary\nRobust assessment separates the two channels deliberately:\n\n- **Comprehension (receptive)** — point-to-picture and follow-direction tasks isolate understanding from output, useful where expressive delay masks intact comprehension.\n- **Expression (expressive)** — confrontation naming, definitional tasks and rapid naming reveal lexical retrieval and word-finding latency.\n- **Spontaneous language sample** — transcribe 50–100 utterances of play-based talk; compute lexical diversity (type–token or moving-average measures) and number of different words, which are sensitive to real-world functional gain.\n- **Caregiver inventories** — for under-3s, parent-report checklists capture vocabulary the child uses at home that a single session may miss.\n\nFor longitudinal tracking, fix the measure, the elicitation context and the interval (commonly 8–12 weekly cycles), then chart change against the child's own entry baseline. Pair quantitative scores with functional goals (e.g. semantic categories, core-vocabulary use for AAC users) so growth maps to participation, per the ICF activity framing (d3).\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — our AbilityScore® is a clinician-administered structured assessment that benchmarks each child against their own baseline.
