The pathway is screen, rule out hearing and structural causes, comprehensive motor-speech assessment, and differential diagnosis. Under ~3 years a provisional designation enables early therapy with serial re-evaluation.","answer_md":"*A child who knows exactly what they want to say but cannot reliably make the mouth do it — that is the puzzle CAS presents, and the pathway is built to solve it precisely.*\n\n## In short\nThere is **no single test** for Childhood Apraxia of Speech (CAS, ICD-11 6A01.0); diagnosis is a clinical judgement made by a paediatric speech-language pathologist after differential motor-speech assessment. The pathway runs **screen → hearing and oral-mechanism check → comprehensive motor-speech evaluation → differential diagnosis**, and a provisional label is appropriate under ~3 years pending confirmation as speech emerges. Refer early — do not wait — because CAS responds to intensive, principled motor-based therapy.\n\n## The diagnostic pathway\n**1. Screen and rule out.** Confirm hearing (audiology) and complete an oral-mechanism exam to exclude structural or dysarthric causes. Establish that receptive language and non-verbal cognition outstrip expressive speech — the hallmark dissociation.\n\n**2. Comprehensive motor-speech evaluation.** Assess across varying utterance length and complexity, including diadochokinetic and multisyllabic tasks. ASHA recognises three consensus features: inconsistent errors on repeated productions, lengthened and disrupted coarticulatory transitions, and inappropriate prosody (notably lexical/phrasal stress).\n\n**3. Differential diagnosis.** Distinguish from phonological disorder, dysarthria and severe expressive delay. In children under 3 with limited speech output, a **working/provisional CAS** designation enables therapy while the profile clarifies with repeated sampling.\n\n**4. Re-evaluation.** Serial assessment tracks change and refines the diagnosis as the speech system matures.\n\n## The Pinnacle way\nA clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed **only at a Pinnacle Blooms Network centre, under qualified clinician care** — never from an app or checklist. Our [speech therapy](/speech-therapy) pathway pairs this structured, clinician-administered profile with motor-speech-specific intervention; see the full [Childhood Apraxia of Speech](/childhood-apraxia-of-speech) overview for families.\n\n## Trusted sources\nASHA technical/position statements on CAS (asha.org); WHO ICD-11 6A01.0 (icd.who.int).\n\n**Next step —** Refer a child with suspected CAS for a paediatric motor-speech evaluation — [partner with a Pinnacle centre](/speech-therapy).\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-is-the-recommended-screening-and-diagnostic-pathway-for-childhood-apraxia-of-speech-in-children-under-7","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
