Your Pediatrician Ran an Autism Screening: Start Here
Take a breath. Whether the M-CHAT came back Medium Risk, High Risk, or the pediatrician suggested waiting, you've landed in the right place. This page walks you through exactly what to do, in order, with links to every tool and resource you need. None of these steps require a formal autism diagnosis.
Step 1: Understand What the Screening Actually Measures
The M-CHAT-R is a 5-minute screener pediatricians use at the 18 and 24-month well-child visits, recommended by the American Academy of Pediatrics. A positive screen doesn't mean autism, it means the threshold for an evaluation has been crossed.
Step 2: Generate Your Personalized 30-Day Plan
Four short questions and we'll generate a step-by-step plan tailored to your child's age, screening result, state, and what you're seeing at home. The plan covers actions for this week, documentation to start, your state's Early Intervention referral path, and what to do if things stall.
Step 3: Self-Refer to Early Intervention (Under 3) or Child Find (3+)
Under federal law (IDEA Part C), every state runs a free Early Intervention program for children under 3, and you don't need a doctor's referral or an autism diagnosis to qualify. Developmental delay is enough. The state has 45 days to complete the evaluation. After age 3, the same right shifts to your local school district under Child Find.
Step 4: Start Documenting What You See
The diagnostic evaluation will ask you for specific examples. Vague concerns lose to specific observations every time. Start a behavior log, capture short phone videos, and run our Sensory Profile Quiz so you walk into the eval with quantified data, not just intuition.
Step 5: Know What to Expect From the Evaluation
The diagnostic evaluation is a 2 to 3-hour clinical assessment using tools like the ADOS-2 and ADI-R, plus a developmental history interview. Going in prepared changes how much you get out of it. State-specific waitlists, costs, and Medicaid waivers vary widely, so check your state's evaluation guide for the local picture.
Step 6: Try Low-Lift Supports That Don't Need a Diagnosis
Sensory accommodations, visual schedules, AAC starter cards, and predictable routines all work for autistic and non-autistic kids alike. Starting them now reduces frustration today and gives you data on what helps before the eval lands.
Step 7: Find Other Parents on the Same Path
The pre-diagnosis stretch is one of the loneliest seasons of parenting. You're not crazy and you're not overreacting. Other parents who walked this road are out there.
You're Already Doing the Right Thing
You showed up to the screen, took it seriously, and are here looking for the next step. Parents flag autism concerns 12+ months before professionals do, on average. Your judgment is data. Bookmark this page and come back whenever you need a next step.
Frequently Asked Questions
- What does a positive M-CHAT result actually mean?
- A positive M-CHAT-R score (3 or higher) means the screen flagged enough items that a follow-up is warranted, not that your child has autism. Roughly 50% of children who screen positive turn out to be autistic on full evaluation; the others typically have a different developmental concern or are typical. The screen tells you the threshold for evaluation has been crossed; the diagnostic appointment tells you the answer.
- Do I need an autism diagnosis before starting Early Intervention?
- No. Under federal law (IDEA Part C), every state runs a free Early Intervention program for children under 3, and developmental delay (not autism specifically) is sufficient to qualify. You can self-refer directly with no doctor's note. The state has 45 days from referral to complete its evaluation. After age 3, the same right shifts to your local public school district under Child Find (IDEA Part B), with a 60-calendar-day response window.
- How long is the typical wait for an autism diagnostic evaluation?
- Wait times in the US currently range from 3 to 18 months depending on geography, insurance, and which specialist you're seeing. National averages are 6 to 9 months. If you're quoted longer than 6 months, escalate: call back weekly for cancellations, ask for a different specialist, consider telehealth options (Cortica, Cognoa). Start Early Intervention services in parallel since they don't require a diagnosis.
- What if my pediatrician says wait and see?
- Parents detect autism concerns 12+ months before professionals on average. Your pediatrician saying wait does not override what you observe at home, and you can self-refer to Early Intervention without their sign-off. If concerns persist, request a developmental pediatrician referral (different from a generalist), change practices, or self-refer directly to your state's Part C program.
- What's the difference between Early Intervention and a school evaluation?
- Early Intervention (IDEA Part C) serves children from birth to age 3 through state-administered programs (Early Steps, Babies Can't Wait, Help Me Grow, and other state-specific names). Child Find (IDEA Part B) serves children 3 and older through your local public school district. Both are free, both require only developmental delay (not an autism diagnosis), and both have legally mandated response timelines. Our Autism Screening Action Plan tool generates the specific referral path for your state.
- Can I take the M-CHAT myself if my pediatrician hasn't?
- Yes. The M-CHAT-R is freely available at mchatscreen.com and takes about 5 minutes. Self-administered scores are a useful starting point. If your child screens Medium or High Risk, take the result to your pediatrician for the formal follow-up interview, or request a referral to a developmental specialist directly.
- If my child screens negative but I still have concerns, what should I do?
- Trust your gut. The M-CHAT-R has high sensitivity but isn't perfect. Some autistic children, especially those with milder presentations, can score Low Risk. If concerns persist: ask for a re-screen at the next well-child visit, request the M-CHAT-R/F follow-up interview anyway to walk through items, and consider a developmental pediatrician evaluation directly. The cost of an extra eval is one appointment; the cost of waiting is the under-3 Early Intervention window closing.
