Referring a child with suspected speech and language delay

A late-talking phase is common — but a clinician's job is to know when watchful waiting ends and structured support begins. Here is the decision framework.

In short

Refer for developmental therapy when language delay is persistent rather than transient, when red flags are present at any age, or when a screen falls below the expected milestone band — do not adopt a wait-and-see stance once these thresholds are crossed. Critically, a speech-language referral should run in parallel with audiology, never after it: confirm hearing first, but do not delay therapy access while you do. Earlier intervention consistently yields better language and literacy trajectories.

Referral thresholds worth acting on

Use these as decision points, not as diagnostic criteria:

• By 12 months — no babbling, pointing or other communicative gestures.
• By 18 months — fewer than a handful of words; no response to name; not following simple one-step requests.
• By 24 months — fewer than ~50 words; no two-word combinations; reliance on gesture alone.
• By 36 months — speech largely unintelligible to unfamiliar adults; not following two-step directions; very limited sentence structure.
• Any age — regression or loss of previously acquired words or skills (refer promptly), parental concern that persists, or delay co-occurring with social-communication, motor or feeding atypicalities.

Always pair the referral with an audiology check and a broader developmental review, since language delay can be the presenting sign of hearing loss, global developmental delay, autism or an oromotor difficulty. WHO classifies developmental speech and language disorders under ICD-11 6A01.

The Pinnacle way

A structured, clinician-administered AbilityScore® assessment and any formal diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — never from an online form or a single observation. Refer directly into speech therapy, where a speech-language pathologist evaluates the child against their own AbilityScore baseline, screens for differential causes, and sets a measurable plan. Across 70+ centres in 4 states, 700+ therapists and 25 million+ therapy sessions, the aim is the same: the child communicating and thriving in the mainstream.

Next step — When thresholds are met, refer without delay. Book a language assessment with a Pinnacle speech-language pathologist, alongside an audiology review.
