Screening & Diagnostic Pathway for DLD Under 7
For children under 7, the pathway is surveillance and validated screening at routine visits, audiological clearance, then multidisciplinary diagnostic evaluation by a speech-language pathologist. DLD (ICD-11 6A01.2) is diagnosed when language difficulty persists, impairs function and is not explained by hearing loss, ASD, intellectual disability or environmental factors. Below ~4 years, monitor rather than label prematurely.

A child who understands far more than they can say is the clinical signature that should prompt structured language assessment.
In short
For children under 7, the recommended pathway is surveillance and screening first, then a multidisciplinary diagnostic evaluation. Use validated screens at routine visits, confirm normal hearing, then refer to speech-language pathology for a standardised language assessment. Developmental Language Disorder (DLD, ICD-11 6A01.2) is diagnosed when language difficulties persist, impair function, and are not explained by hearing loss, a known biomedical condition (e.g. ASD, intellectual disability) or differentiating environmental factors.
The pathway
1. Surveillance & screening. At well-child contacts, monitor milestones and elicit parental concern (a strong predictor). Apply a validated tool — late-talker watch at 18–30 months; structured screening where expressive/receptive delay persists. No babble/gesture by 12m, no words by 16m, no two-word phrases by 24m warrant action.
2. Rule out the obvious. Confirm audiological assessment to exclude hearing loss. Review for global delay, ASD features, neurological signs and bilingual exposure (assess in all languages — bilingualism does not cause DLD).
3. Diagnostic evaluation. Refer to a speech-language pathologist for norm-referenced assessment across expressive and receptive domains, narrative and functional impact. DLD is the diagnosis when difficulties persist beyond age 5, are unlikely to resolve, and lack a differentiating condition. Below ~3–4 years, frame as language delay under monitoring rather than premature labelling.
The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from a screen or app. Our speech therapy and developmental language disorder pathways pair structured assessment with a measurable baseline via the clinician-administered AbilityScore®.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Persistent expressive/receptive gap, no two-word phrases by 24 months, normal hearing yet limited language, and impact across home and preschool settings.
In everyday life
Always assess a bilingual child across all their languages — strength in one language with difficulty in all rules against DLD being mislabelled.

Bring your questions to a first visitQuestions families ask
At what age can DLD be reliably diagnosed?
Many late talkers resolve by 3–4 years, so diagnosis becomes more reliable once difficulties persist beyond age 5. Before that, frame as language delay under active monitoring with periodic reassessment rather than a fixed label.
Does bilingualism cause DLD?
No. Bilingual exposure does not cause language disorder. DLD presents as difficulty across all of a child's languages, so assessment must consider every language the child uses before any diagnosis is considered.
What must be excluded before diagnosing DLD?
Confirm hearing via audiology, and rule out a differentiating biomedical condition such as ASD, intellectual disability or neurological disorder. DLD (6A01.2) is the diagnosis when persistent language difficulty is not better explained by these.
