Where Do I Start?

If you're looking to begin the process of getting a childhood autism diagnosis, the path outlined below will help you on that journey.

1. Start with Your Pediatrician or Primary Care Provider

This is the best starting point. A pediatrician:

  • Can do developmental screenings during regular checkups.

  • Will assess concerns about social, communication, or behavioral delays.

  • Can provide referrals to specialists if needed.

Tip: Bring specific examples of behaviors you've noticed (e.g., delayed speech, lack of eye contact, repetitive movements, difficulty with social interaction).

2. Developmental Screening

If the pediatrician shares your concerns, they may conduct or refer you for:

  • M-CHAT-R/F: A common autism screener for toddlers (16–30 months).

  • Other developmental milestone assessments.

3. Get a Referral for a Diagnostic Evaluation

If screening suggests further evaluation, you’ll likely be referred to one or more of the following:

  • Developmental Pediatrician

  • Child Psychologist or Psychiatrist

  • Pediatric Neurologist

These professionals can perform a comprehensive autism diagnostic evaluation, which may include:

  • Observation

  • Parent interviews

  • Standardized tools like the ADOS-2 and ADI-R

4. Contact Early Intervention Services (If Under Age 3)

In the U.S., you can get a free evaluation through Early Intervention (EI) programs:

  • Provided by each state

  • No formal diagnosis is required to qualify for services

5. If the Child Is Over Age 3

Contact your local public school district for a free educational evaluation through:

  • Child Find (mandated by IDEA law in the U.S.)

  • This can lead to an IEP (Individualized Education Program)

Extra Tips:

  • Document behaviors: Videos, notes, and timelines help.

  • Don’t wait: You don’t need a diagnosis to start services like speech or occupational therapy.

  • Insurance: Check what services are covered under your plan.
