Your child is not talking as much as other children the same age. They avoid eye contact. Something feels different. Your first question is: how do I get an autism test for my child in India? This guide walks you through every step — from the first signs to watch for, to the screening tools available, to where to go and what it costs.

In India, autism screening starts with a developmental paediatrician who uses validated tools like M-CHAT (for toddlers), ISAA, or CARS-2 for formal assessment. Free assessment is available at AIIMS, NIMHANS, and government hospitals. Do not wait for your child to outgrow concerns — earlier assessment and intervention produce dramatically better outcomes.

1. Early Signs: Autism Symptoms Checklist by Age

Before any formal autism test for child is done, parents typically notice specific concerns at home. Here is an autism checklist India parents can use to track their observations:

6-12 mo
No social smiling in response to your smile

Does not smile back when you smile at them; limited eye contact during feeding or play

12 mo
Not pointing, waving, or responding to name

No index-finger pointing to show interest; does not respond consistently when name is called; hearing test normal

16 mo
No single meaningful words

Has not said mama, dada, or any intentional word by 16 months

18-24 mo
No two-word spontaneous phrases

Cannot combine two words; may have regressed — lost words that were present earlier

Any age
Loss of previously acquired skills

Any regression in language, social skills, or play is a red flag requiring immediate assessment regardless of age

Any age
Repetitive movements or behaviours

Hand-flapping, rocking, spinning objects, insistence on sameness, intense fixation on specific topics

Autism test ke liye kab jaayein: If your child shows 2 or more items from this autism symptoms checklist, consult a developmental paediatrician promptly. Do not wait — the earlier you act, the better the outcome.

2. What Is the M-CHAT Autism Screening Test?

M-CHAT kya hai — एम-चैट ऑटिज़्म स्क्रीनिंग टेस्ट
The M-CHAT (Modified Checklist for Autism in Toddlers) is a 20-question parent-completed autism screening tool validated for children aged 16-30 months. It is the most widely used first-level autism screening tool globally. A positive M-CHAT result means your child is at elevated risk and needs further evaluation — it is NOT a diagnosis of autism.

The M-CHAT Hindi version and the M-CHAT India adapted versions are available through Action for Autism India. Key questions include whether the child points to show interest, follows your pointing gesture, enjoys social games like peek-a-boo, and makes eye contact.

Important for Indian parents: The M-CHAT is a screening tool, not a diagnostic test. A positive result means see a specialist now. A negative result does not guarantee no autism. If you have concerns despite a negative M-CHAT, trust your instincts and seek assessment anyway. Beyond M-CHAT, the Indian Autism Screening Questionnaire (IASQ) derived from the ISAA is increasingly used across India as a culturally appropriate screening tool.

3. Autism Diagnosis Tools Used in India

ToolWhat It IsWho Uses ItAge Range
M-CHAT / M-CHAT-R/F20-question parent screening checklist; most widely used globallyPaediatricians, primary care16-30 months
ISAA (Indian Scale for Assessment of Autism)India’s mandated 40-item autism assessment scale; Government of India toolDevelopmental specialists, government hospitals2+ years
IASQ (Indian Autism Screening Questionnaire)Shorter screening tool derived from ISAA; usable by minimally trained workersPrimary health workers, NGOs, paediatricians2-9 years
CARS-215-item clinician-rated scale; widely available; distinguishes autism from other conditionsPsychologists, developmental paediatricians2+ years
ADOS-2Gold-standard observational assessment; requires trained examiner; most accurateSpecialist centres, research hospitals12 months+
For most Indian families: The assessment journey starts with M-CHAT or IASQ screening, then ISAA or CARS-2 clinical assessment, and at specialist centres, ADOS-2 for confirmed diagnosis. The ISAA score is required for the government disability certificate under the RPWD Act 2016.

4. How to Get an Autism Test in India: Step-by-Step

Step 1: Document your observations

Write down specific examples of your concerns with dates. Video examples on your phone are extremely helpful. The more specific you are, the more efficiently the specialist can work.

Step 2: Visit your paediatrician

Share your documented concerns. Ask for M-CHAT or IASQ screening at this visit. Request a referral to a developmental paediatrician. If concerns are dismissed, seek a second opinion or go directly to a developmental specialist.

Step 3: Developmental paediatrician appointment

The specialist will take a detailed developmental history, observe your child, and administer ISAA, CARS-2, or ADOS-2 depending on the centre. Appointment typically takes 1-3 hours. Bring video of your child at home.

Step 4: Receive the assessment report

You will receive a written report specifying findings, severity level (DSM-5 Level 1, 2, or 3), and recommended interventions. Ask for an explanation of each recommendation.

Step 5: Apply for disability certificate

An autism diagnosis entitles your child to a disability certificate under the RPWD Act 2016. The certificate unlocks educational support, reservations, and tax benefits. See our free autism resources guide for full details.

Step 6: Begin early intervention immediately

Start speech therapy and occupational therapy as soon as possible — ideally before the formal diagnosis is complete. Early communication support is the highest-impact intervention available. Managing sensory processing challenges alongside communication is also critical.
