Autism Checklist India — Age-Wise Signs, Red Flags & When to Act

You’ve noticed something that doesn’t quite fit and you’re looking for a concrete checklist to compare against. This autism checklist for Indian parents covers every age from 6 months to school age — with specific red flags, a Hindi reference section, and clear guidance on when to act.

Autism checklist India — key red flags by age: No social smile (6 months); no babbling (9 months); no pointing, waving, or name response (12 months); no words (16 months); no 2-word phrases (24 months); skill regression at any age. For children aged 16–30 months, the free M-CHAT at mchatscreen.com is the best validated screening tool. Any significant concern warrants immediate professional evaluation.

1. How to Use This Autism Checklist

  • Observe typical behaviour — not best performance. How does your child usually behave at home?
  • Look for patterns — occasional differences are normal. Consistent, significant differences across multiple areas are concerning.
  • Don’t self-diagnose — use this checklist to decide whether to seek professional assessment.
  • Act on any concern — there is no downside to seeking evaluation. There is a significant downside to delaying it.
One rule overrides everything: If your child has lost skills they previously had — words, social engagement, eye contact — seek a same-day or next-day medical appointment. Skill regression is the most urgent autism red flag at any age.

3. Autism Checklist in Hindi

Autism Checklist Hindi Mein — ऑटिज़्म के प्रमुख संकेत

देर से बोलना (Speech delay) — 18 महीने में कोई शब्द नहीं; 24 महीने में दो शब्दों का वाक्य नहीं
आँखें न मिलाना (Poor eye contact) — लोगों की आँखों में नहीं देखता, खासकर बातचीत के दौरान
नाम पर कोई प्रतिक्रिया नहीं (No name response) — नाम लेने पर नहीं मुड़ता, सुनने में कोई समस्या नहीं
उँगली से इशारा न करना (No pointing) — दिलचस्प चीज़ें दिखाने के लिए उँगली नहीं उठाता
एक ही काम बार-बार करना (Repetitive behaviours) — एक ही खिलौना एक ही तरह से, वस्तुएं लाइन में लगाना
दिनचर्या में बदलाव से परेशान होना (Routine insistence) — छोटे बदलाव पर बहुत तेज़ प्रतिक्रिया
बोलना बंद हो जाना (Regression) — यह तुरंत डॉक्टर के पास जाने का संकेत है

4. Autism Checklist for Older Children — 3 to 8 Years

AreaSigns in 3–8 Year Olds
CommunicationVery literal; doesn’t understand jokes or sarcasm; unusual speech rhythm; extensive vocabulary but struggles with back-and-forth conversation
SocialStruggles with friendships; doesn’t understand unwritten social rules; difficulty with group play; prefers adults or younger children
PlayVery focused on specific topics to the exclusion of others; may be very knowledgeable about one subject
BehaviourStrong preference for sameness; distress with change; sensory sensitivities to clothing fabrics, food textures, sounds
Girls often present differently: Autistic girls in India are frequently missed — they often mask social difficulties more effectively, have fewer obvious repetitive behaviours, and mimic peers. If your daughter shows social difficulties, anxiety, and sensory sensitivities — even without obvious behavioural signs — autism should be considered.

5. The 3-Domain Autism Checklist

The DSM-5 autism diagnostic criteria covers two domains:

  • Domain A — Social Communication and Interaction: Difficulty with back-and-forth conversation; limited eye contact; doesn’t share enjoyment; difficulty adjusting behaviour to social context; reduced interest in relationships.
  • Domain B — Restricted and Repetitive Behaviours: Repetitive movements or speech; insistence on sameness; highly restricted, intense interests; hyper- or hyposensitivity to sensory input.

For diagnosis, a child must show significant differences in Domain A and at least two features from Domain B, present from early development and causing significant impact on daily functioning.

6. ISAA — India’s Official Autism Assessment Scale

The Indian Scale for Assessment of Autism (ISAA) is the official autism assessment tool used by specialists in India. Developed by NIMHANS and the National Trust, specifically validated for the Indian population.

  • Age range: 2–9 years
  • Items: 40 items across social relationship, emotional responsiveness, speech and language, behaviour patterns, sensory aspects, and cognitive component
  • Administered by: Trained psychologists or paediatricians — not a parent self-report tool
  • Used for: Formal autism diagnosis in India and for the RPWD disability certificate

M-CHAT is a screening checklist for parents of toddlers. ISAA is a full clinical assessment tool. Both are important — they serve different stages of the pathway.

7. After the Checklist — What to Do

  1. Take the M-CHAT online (for children 16–30 months) at mchatscreen.com
  2. Document your observations with video clips, notes, and dates
  3. See your paediatrician this week — bring your documentation
  4. Request a referral to a developmental paediatrician or child psychiatrist
  5. Start speech therapy now if there is any speech delay — communication support doesn’t need a diagnosis to begin
  6. Contact: Action for Autism India (011-45565700), NIMHANS (080-46110007), or your nearest National Trust centre
