Autism Spectrum
When to refer a child with possible autism to a specialist
Refer on suspicion, not certainty. Any recognised red flag, any loss of skills at any age, or a worried parent is reason enough to refer for specialist assessment. Screen hearing first. A referral opens the door to early support — only a clinician diagnoses.
You are often the first person a worried family talks to — and your timely referral can change a child's whole trajectory.
In short
Refer without waiting if a child shows any of the recognised red flags, if a parent reports a loss of skills (regression) at any age, or simply if your own developmental gut feeling says something is not right. In autism, you do not wait to be certain — you refer on suspicion, because early assessment and early support carry the strongest evidence for good outcomes. A referral is not a diagnosis; it is a door to clarity.What to watch — refer if you see these
- By 12 months — no babbling, pointing or other gestures; no response to own name
- By 16 months — no single words
- By 18 months — not pointing to share interest; little eye contact; not following a point
- By 24 months — no meaningful two-word phrases (not just imitating)
- Any age — loss of previously gained speech, babble or social skills (regress = refer urgently)
- Any age — limited social smiling, reduced shared attention, strong repetitive behaviours, intense distress at routine change, or a parent who is worried
Also screen hearing first — undetected hearing loss can mimic these signs.
The science, briefly
WHO classifies autism spectrum disorder under ICD-11 6A02. NICE (CG128) and the CDC's Learn the Signs. Act Early. programme both endorse referral on suspicion rather than delay, and IAP guidance supports developmental surveillance at every well-child contact. Parental concern is one of the most reliable early signals in the evidence — take it seriously.The Pinnacle way
No diagnosis or AbilityScore® is ever made from a form, a phone call or this page — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under a qualified clinician. Once you refer, families reach structured assessment and, where needed, autism therapy and speech therapy early — when it counts most.Trusted sources

What to watch
Refer urgently if a child loses words, babble or social skills they once had. Refer if there is no name response or gesture by 12 months, no words by 16 months, no pointing to share by 18 months, or no two-word phrases by 24 months — or whenever a parent is worried.
Try this at home
Trust parental concern and document it plainly. At every well-child visit, ask one open question — 'Is there anything about how your child plays, talks or responds that you wonder about?' — and act on the answer.

Frequently asked
Should I wait until I'm sure before referring?
No. In autism you refer on suspicion, not certainty. Early assessment carries the strongest evidence for good outcomes, and a referral is simply a door to clarity — never a diagnosis. When in doubt, refer.
What is the single most urgent red flag?
Loss of previously gained skills — speech, babble or social behaviours — at any age. Regression warrants prompt referral. Always screen hearing too, as undetected hearing loss can mimic these signs.
How much weight should I give to what the parent says?
A great deal. Parental concern is one of the most reliable early signals in the evidence. If a parent is worried, that alone is reason enough to refer for specialist assessment.
