Red flags for Developmental Language Disorder that warrant referral

A young child arrives not with a diagnosis but with a parent saying "they just aren't talking like the others" — and the first clinician to take that seriously changes the trajectory.

In short

Refer for language assessment when expressive and/or receptive language is persistently below age expectation, is not explained by hearing loss, global developmental delay, autism or a known biomedical condition, and is functionally limiting. Act most urgently on any loss of language skills, no babble or gesture by 12 months, no single words by 16 months, no two-word combinations by 24 months, and parental concern that does not resolve.

Red flags that warrant referral

Expressive

• No babbling by 12 months; first words delayed beyond 16 months
• No two-word phrases by 24 months; vocabulary <50 words at 24 months
• Persistent reliance on gesture/pointing in place of words beyond expected age
• Marked word-finding difficulty, limited sentence length, or grammatical errors persisting beyond peers

Receptive

• Reduced comprehension of simple instructions or questions for age
• Difficulty following routine multi-step directions in a familiar context

Always act on

• Any regression — loss of previously acquired words or babble at any age (urgent same-week referral; rule out Landau–Kleffner and hearing loss)
• Persistent parental concern — a sensitive early indicator

When to refer

"Wait and see" is not appropriate when these signs persist across settings. A child need not meet full ICD-11 6A01.2 criteria to warrant referral. Always arrange an audiology check in parallel, and refer for speech therapy assessment while formal evaluation is organised. DLD is diagnosed only when the difficulty is not attributable to another condition; differentiating from a language delay associated with autism or global delay is part of the multidisciplinary assessment.

The Pinnacle way

Pinnacle Blooms Network supports your referral with structured, multi-domain developmental profiling. The clinician-administered AbilityScore® gives an objective baseline that complements your impression and tracks change once intervention begins. It supports, and never replaces, clinical judgment — a formal DLD diagnosis and any AbilityScore® are formed only at a Pinnacle Blooms Network centre under qualified clinician care, never the output of a screen.

Trusted sources

Aligned with WHO ICD-11 (6A01.2), ASHA guidance on language disorders, NICE early-language referral standards, and the CATALISE consensus on identifying DLD.
