The strongest evidence supports **phonological/minimal-pair approaches**, **traditional articulation (motor) therapy**, and — for childhood apraxia of speech — **motor-learning principles such as DTTC and PROMPT**. High-dose, distributed practice with parent-mediated home carryover consistently outperforms low-frequency, isolated drilling.\n\n## The science\n- **Phonological approaches** (minimal pairs, maximal oppositions, cycles) — first-line where errors are rule-based and pattern-driven; they reorganise the child's sound system rather than one sound at a time. Strong guideline support for moderate–severe phonological disorder.\n- **Traditional articulation therapy** (Van Riper motor hierarchy: isolation → syllable → word → sentence → conversation) — effective for residual or distortion errors with a stable phonological system.\n- **Motor-speech approaches for CAS** — Dynamic Temporal and Tactile Cueing (DTTC) and tactile-kinaesthetic cueing operate on motor-learning principles (high repetition, variable practice, knowledge of results); these are the recommended frameworks for childhood apraxia of speech.\n- **Dosage matters** — frequent, distributed sessions with high trial counts and structured home practice drive generalisation. Parent coaching extends practice into daily routines.\n- Always exclude or address **hearing, oral-structural and oral-motor contributors** first, with audiology and paediatric review as indicated.\n\n## When to refer\nRefer for assessment when speech is markedly less intelligible than peers, when intelligibility to unfamiliar listeners is low beyond the expected age range, when groping or inconsistent errors suggest motor-speech involvement, or where any hearing concern exists.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment.
