YOUR QUESTION. A CLEARER NEXT STEP.
When to refer a child with suspected autism for developmental therapy
Refer at the point of suspicion, not after diagnosis. A failed autism screen, any loss of skills, missed social-communication milestones or persistent parental concern should trigger dual-track referral: diagnostic evaluation plus concurrent developmental therapy, without waiting for a formal label.

A worried parent in front of you with a 'wait and watch' instinct deserves a clearer rule — refer on suspicion, not on certainty.
In short
Referral for developmental therapy is appropriate at the point of suspicion, not after diagnostic confirmation. If a child fails an autism-specific screen (e.g. M-CHAT-R/F), shows a parental concern about social communication, loses previously acquired language or social skills at any age, or misses social-communication milestones, refer concurrently for diagnostic assessment and early intervention. Do not delay therapy while awaiting a formal label — early enrolment improves trajectories, and intervention is benefit-led regardless of diagnostic outcome.
Referral decision points
Refer promptly when any of the following are present:
- Positive or high-risk autism screen — M-CHAT-R/F failed or borderline at 18- and 24-month visits.
- Red-flag absolute indications — no babbling by 12 months, no single words by 16 months, no two-word phrases by 24 months, or any loss of language or social skills at any age. These warrant immediate referral, per AAP and CDC guidance.
- Persistent social-communication concern — reduced eye contact, limited joint attention, absent social referencing, restricted/repetitive behaviours or atypical sensory responses persisting across settings.
- Parental concern — caregiver-reported concern is itself a validated trigger to act; surveillance plus screening should escalate to referral rather than reassurance alone.
The principle is dual-track referral: send for diagnostic evaluation (ICD-11 6A02) while simultaneously initiating developmental therapy. NICE CG128 supports recognition pathways that begin intervention without waiting for protracted assessment queues, and IAP developmental surveillance endorses acting on first concern.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — never from a screen or an online form. On referral, the child receives a clinician-administered structured assessment establishing their own baseline, and a domain-specific plan spanning speech therapy and broader autism developmental support. Drawing on 25 million+ therapy sessions across 70+ centres, we accept referred children for therapy concurrently with diagnostic work-up, so no time is lost.
Trusted sources

Next step — Refer on suspicion. Book a developmental assessment and let the diagnostic pathway and early therapy run in parallel.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Treat any loss of previously acquired language or social skills at any age as an absolute red flag warranting immediate referral. Also escalate when caregiver concern persists despite a passed screen, or when restricted/repetitive behaviours appear across multiple settings.
In everyday life
When counselling parents, frame the referral as a check, not a verdict: developmental therapy benefits the child regardless of the eventual diagnostic outcome, which removes the pressure to 'be certain' before acting.

Bring your questions to a first visitQuestions families ask
Should I wait for a confirmed diagnosis before referring for therapy?
No. Best practice is dual-track referral — send for diagnostic evaluation and initiate developmental therapy concurrently. Early intervention improves trajectories and benefits the child regardless of the final diagnostic outcome, so waiting on a formal label only loses valuable time.
What screening result justifies a referral?
A failed or borderline M-CHAT-R/F at the 18- or 24-month visit justifies referral. Equally, validated parental concern about social communication, or any red-flag indicator, is sufficient to act on without a positive screen.
Which findings are absolute red flags for immediate referral?
No babbling by 12 months, no single words by 16 months, no two-word phrases by 24 months, and — most critically — any loss of previously acquired language or social skills at any age, per AAP and CDC guidance.
Does referral commit the family to an autism diagnosis?
No. Referral initiates a clinician-administered structured assessment that establishes the child's own baseline and looks for other explanations first. A diagnosis is only ever formed by a qualified clinician at a centre, never from a screen.
