These approaches outperform isolated drill because they pair each target word with rich, repeated, contextual meaning. For children with delay, structured naturalistic developmental behavioural interventions (NDBI) and Enhanced Milieu Teaching add explicit prompting hierarchies within the same responsive frame.\n\n## The science\n- **Responsive interaction & language modelling** — following attentional focus, labelling, expanding the child's utterance and recasting errors. Robust evidence links adult responsiveness and contingent talk to vocabulary growth.\n- **Dialogic reading (PEER/CROWD)** — the adult prompts, evaluates, expands and repeats during shared books; meta-analytic data show meaningful expressive vocabulary gains, strongest in younger children.\n- **Enhanced Milieu Teaching & NDBI** — combine environmental arrangement, modelling, mand-model and time-delay prompts to embed targets in play; effective for children with language delay or autism.\n- **Focused stimulation & vocabulary targeting** — high-frequency exposure to a small set of functional target words across contexts.\n- **Dose matters** — frequency of communicative opportunities and parent-coaching to generalise into the home environment are key mediators of outcome.\n\n## When to refer\nRefer for a speech-language assessment where expressive vocabulary is markedly below expectations for age, plateaus, or is paired with limited gesture, comprehension or social communication concerns.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment.
