YOUR QUESTION. A CLEARER NEXT STEP.
Autism screening & diagnostic pathway under 7
For children under 7, the pathway is developmental surveillance at every visit, autism-specific screening at 18 and 24 months (and at any concern), prompt referral on a positive screen, and multidisciplinary diagnostic assessment against ICD-11 6A02. Screening flags risk; it never diagnoses. A clinical AbilityScore and diagnosis are formed only at a Pinnacle centre.

A child rarely presents with a diagnosis — they present with a pattern, and a clear pathway turns that pattern into timely support.
In short
For children under 7, the recommended pathway is surveillance at every visit, structured screening at defined ages, and prompt referral to a multidisciplinary team for diagnostic assessment when concern persists. AAP/IAP advocate developmental surveillance at all well-child visits with formal autism-specific screening (e.g. M-CHAT-R/F) at 18 and 24 months, plus screening at any point of parental or clinician concern. A positive screen is a trigger for referral — not a diagnosis. Diagnosis is established by clinical history, direct observation against ICD-11 6A02 criteria, and standardised tools, never by screen alone.
The pathway
1. Surveillance — track milestones at every contact; act on regression at any age. 2. Screening — autism-specific tool at 18 and 24 months, or whenever flags emerge; pair with a hearing check to exclude sensory cause. 3. Referral — on a positive screen or persistent concern, route to a multidisciplinary developmental team without waiting. 4. Diagnostic assessment — detailed developmental and family history, multi-setting behavioural observation, and instruments such as ADOS-2/ADI-R, mapped to ICD-11 6A02 (NICE CG128). Co-occurring needs — language, cognition, sensory, sleep, feeding — are profiled in parallel. 5. Intervention — early evidence-based support begins alongside, not after, formal diagnosis.
NICE CG128 and NIMHANS resources reinforce that delay to assessment should never delay support.
The Pinnacle way
A clinical AbilityScore® — a clinician-administered structured developmental assessment — and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from a screen or an app. Across 70+ centres in 4 states, our multidisciplinary teams convert a positive screen into a profiled plan. See how the AbilityScore® works and our autism therapy pathway.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Persistent social-communication differences and restricted, repetitive behaviour across settings; any regression at any age; a positive M-CHAT-R/F that warrants follow-up interview and referral.
In everyday life
Document parental concern verbatim — caregiver report is a strong early signal and should escalate surveillance to formal screening, even between scheduled visits.

Bring your questions to a first visitQuestions families ask
At what ages should autism-specific screening occur?
AAP and IAP recommend autism-specific screening at 18 and 24 months, alongside developmental surveillance at every well-child visit and screening at any point of parental or clinician concern.
Does a positive screen mean a diagnosis?
No. A positive screen indicates raised likelihood and triggers referral for diagnostic assessment. Diagnosis requires clinical history, multi-setting observation and standardised tools mapped to ICD-11 6A02 criteria.
Should support wait until diagnosis is confirmed?
No. NICE CG128 and NIMHANS resources stress that early evidence-based intervention should begin alongside the diagnostic process, not after it. Diagnostic delay should never delay support.
