Your child is 18 months old and your paediatrician mentioned the M-CHAT. Or you found it while searching online after noticing your toddler doesn’t point or respond to their name. This guide explains exactly what the M-CHAT autism test in India is, how to use it, and what the result means.
What is M-CHAT? The M-CHAT (Modified Checklist for Autism in Toddlers, Revised with Follow-Up) is a validated free 20-question parent-report screening tool for children aged 16–30 months. Available free at mchatscreen.com, takes 5 minutes. Gives Low/Medium/High risk result. It screens for autism risk — it cannot diagnose autism. A high-risk result means your child needs professional evaluation, not that they have autism.
1. What Is the M-CHAT Test?
M-CHAT = Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F)
Developed by Dr. Diana Robins and colleagues, published 2014. Validated across multiple countries including India. The “R” means Revised; the “F” means Follow-Up — a structured interview to clarify borderline answers.
In Hindi: M-CHAT एक मुफ्त जाँच उपकरण है जो 16-30 महीने के बच्चों में ऑटिज़्म के जोखिम की जाँच करता है।
The M-CHAT is a screening tool — like a smoke detector. If it goes off, you investigate further. Its purpose is to flag toddlers who should be evaluated by a specialist before autism would otherwise be detected.
2. Who Should Take the M-CHAT?
The M-CHAT is designed for parents of children aged 16–30 months. Consider taking it if your child doesn’t respond to their name (hearing normal), doesn’t point to share interest, has speech delay, shows little interest in other children, or you simply have a gut feeling something is different.
3. The 5 Domains M-CHAT Assesses
| Domain | What It Checks | Example Questions |
|---|---|---|
| Joint Attention | Does your child share interest in things with you? | Does your child point to show interesting things? Look where you point? |
| Social Interest | Is your child interested in other people? | Does your child show interest in other children? |
| Imitation | Does your child copy what others do? | Does your child imitate waving, clapping? |
| Communication | Does your child use gestures and words? | Uses index finger to point? Responds to name? |
| Pretend Play | Can your child pretend? | Does your child pretend (feed a doll, talk on toy phone)? |

5. Understanding Your M-CHAT Result
| Result | Score | What It Means | What To Do |
|---|---|---|---|
| Low Risk | 0–2 items | No significant autism risk indicators | Continue routine check-ups; rescreen at 24 months if concerns |
| Medium Risk | 3–7 items | Some indicators present | Complete follow-up interview; discuss with paediatrician within a month |
| High Risk | 8–20 items, or 2+ critical items | Multiple risk indicators — urgent evaluation | Seek developmental paediatrician referral this week; start speech therapy now |
6. M-CHAT in India — How Paediatricians Use It
In India, the M-CHAT is increasingly used by developmental paediatricians and general paediatricians during 18-month and 24-month well-child visits. The Indian Academy of Pediatrics recommends autism screening at these milestone visits.
Alongside M-CHAT, Indian clinicians also use the ISAA (Indian Scale for Assessment of Autism) — developed specifically for India by NIMHANS and the National Trust. ISAA covers children aged 2–9 years across 40 items and is used for formal diagnostic assessment and RPWD disability certificate processes.
7. After M-CHAT — What Comes Next
High Risk Result
Seek a developmental paediatrician referral this week. Start speech therapy now — don’t wait for a diagnosis. Contact NIMHANS (080-46110007), AIIMS (011-26588500), Action for Autism (011-45565700), or your nearest National Trust centre.
Medium Risk Result
Complete the follow-up interview. Discuss results with paediatrician. If concerns remain after follow-up, request specialist referral.
Low Risk — But Still Concerned
Trust your instincts. The M-CHAT is not perfect — it misses some cases. A professional opinion is always valid regardless of the score.
