How to get an autism diagnosis for your child in Minnesota
The path to an autism diagnosis in Minnesota runs: a concern → a screening → a diagnostic evaluation (and, for state-funded therapy, a CMDE) → services. It usually takes months, not weeks — but you don't have to wait to act. Free early-intervention help can start before any diagnosis, and this guide walks every step.

Noticing signs: when a worry is worth a conversation
You know your child better than any checklist. If something about how they communicate, play, or respond to others keeps tugging at you, that's enough reason to ask — you never need to be sure before you speak up.
Every sign here can also be ordinary development, a hearing issue, or a speech delay. Signs mean “ask,” not “autism.” The next step isn't a conclusion — it's a screening.
Ages 2–3
- Few or no words, or losing words they once had
- Not pointing to show you interesting things
- Not responding to their name
- Deep distress at small changes in routine
Ages 4–5
- Little or no pretend play
- Echoing phrases instead of back-and-forth conversation
- Intense focus on specific objects or routines
- Playing beside other children, rarely with them
School age
- Conversations that stay one-sided
- Big reactions to sounds, textures, or transitions
- Rigid rules for how play must go
- Friendships that feel harder than they should
Milestones adapted from the CDC's Learn the Signs. Act Early. checklists — worth bookmarking for every well-child visit.
Stage 2 of 7journey map
My child screened positive on the M-CHAT — does that mean autism?
No. The M-CHAT-R/F (Modified Checklist for Autism in Toddlers, Revised with Follow-Up) is a 20-question parent screening questionnaire for toddlers 16–30 months old. A positive screen means “follow up and evaluate” — it is never a diagnosis.
Most children who screen positive do not go on to an autism diagnosis — but a positive screen does mean an evaluation is worth doing, and many of these children benefit from early support whatever the eventual answer.
The questionnaire is copyrighted by its authors — take it with your pediatrician or at the official source, mchatscreen.com. A one-line definition lives in our glossary.
What the score means
Low likelihood
No follow-up needed. If your child is under 24 months, screen again at 24 months.
Moderate likelihood
The pediatrician asks the Follow-Up questions (the “F”). If the score stays elevated, that's a positive screen — referral for evaluation and early intervention.
High likelihood
Skip the follow-up questions — go straight to referral for a diagnostic evaluation and early intervention.
Score bands per the official M-CHAT-R/F scoring guidance at mchatscreen.com.
What to do next, by age
Under 3
Call Help Me Grow Minnesota — it's free, needs no diagnosis or doctor's order, and parents can self-refer. Bring the screening result to your pediatrician too.
Approaching or over 3
Ask your pediatrician for an evaluation referral, and read the evaluation paths below.
A positive screen at 24–30 months lands in exactly the window where early intervention and the evaluation process can run in parallel — you don't finish one to start the other. What starting therapy looks like.
Stage 3 of 7journey map
Where can my child be evaluated in Minnesota?
Three paths — and they unlock different doors. Many families end up doing two of them.
Medical diagnostic evaluation
By a developmental pediatrician, child psychologist, or child psychiatrist. Produces — or rules out — a DSM-5 diagnosis of autism spectrum disorder.
Unlocks: insurance-funded care
CMDE
A Comprehensive Multi-Disciplinary Evaluation — Minnesota's evaluation for EIDBI eligibility, the state benefit that funds therapy like ABA. A CMDE is not the same thing as a medical diagnostic evaluation — the CMDE page explains the difference.
Unlocks: the EIDBI path
School-district evaluation
Free, from age 3 up, requested in writing from your district. It produces an educational determination for school services — not a medical diagnosis.
Unlocks: an IEP and school services

Where to get an autism evaluation in MinnesotaStage 4 of 7journey map
What happens at an autism evaluation?
A few hours of structured play with your child, detailed questions for you, and careful observation — commonly spread over one to three visits, depending on the clinic. There are no needles and no pass/fail. You'll leave with next steps, and a written report usually follows within a few weeks.
Your child cannot fail this. If they melt down, won't talk, or ignore the examiner entirely — that's information, not a spoiled appointment. Evaluators who work with young children expect all of it, and a hard day doesn't skew the result.
How to tell your child where you're going: keep it honest and small — “We're going to play some games with a new person, and I'll be right there.” Never frame it as a test, because it isn't one.
What to gather beforehand
- Your referral paperwork and insurance or Medical Assistance (MA) card
- Your own notes — and short phone videos of the behaviors you see at home. Clinicians genuinely use these; home behavior often differs from clinic behavior.
- Records you already have: well-child visit notes or M-CHAT results, daycare or teacher observations, any Help Me Grow or school reports, a hearing test if one's been done
- Comfort items and snacks — and schedule around nap if you can
What actually happens
The caregiver interview
A long, detailed conversation about your child's development — pregnancy to now. It can feel like being quizzed on your parenting; it isn't. The evaluator is building a pattern, not a judgment.
Direct observation
The evaluator plays with your child in a structured way — often using the ADOS-2, which to your child looks like games, bubbles, pretend play, and picture books. What each test measures is decoded on the assessments page.
Some clinics use a multi-disciplinary team — psychologist plus speech, occupational therapy, or a nurse practitioner — and others a single experienced clinician. Both are legitimate ways to reach a diagnosis; Minnesota's CMDE takes the team approach.
Stage 5 of 7journey map
Getting the results: reading the report like a roadmap
How results arrive varies — some clinics share impressions the same day, some schedule a feedback visit, some mail the report. Ask the clinic what to expect before you leave, and don't read anything into the wait.
If the answer is “not autism” — or “not yet clear”: that happens, and it doesn't close doors. Evaluators may suggest watchful waiting and a re-check in 6–12 months. Your concerns still count — Help Me Grow (under 3) and school early-childhood special education (3+) support children based on needs, not diagnosis.
What the report contains
- Whether your child meets DSM-5 criteria for autism spectrum disorder (ASD) — or doesn't
- If yes, a level (1, 2, or 3). Levels describe how much support your child currently needs — not how capable they are or will become. Levels, explained
- Often co-occurring findings: language delay, ADHD traits, sensory differences
- The recommendations section — read it twice. This is the part insurers, EIDBI, and schools act on. It's the roadmap.
Before you leave, ask these four questions
- “What should we do first?”
- “Does this evaluation include or count as a CMDE for EIDBI?” — a huge time-saver in Minnesota if yes (here's why)
- “Who gets a copy, and how do I get more?”
- “When, if ever, should we re-evaluate?”
Stage 6 of 7journey map
While you wait: what can start before the diagnosis
Honesty first: in Minnesota, waits for a diagnostic evaluation commonly run several months — and sometimes closer to a year — depending on the clinic and your child's age. Ask every clinic for its current estimate.
Ask to join the cancellation list. Short-notice openings are real, and they go to the families who asked.
The wait is not wasted time — none of this requires a diagnosis:
Help Me Grow Minnesota
Free, parent self-referral at helpmegrowmn.org. Under 3: Part C early-intervention services at home. Ages 3–5: preschool special education through your school district. No doctor's order, no diagnosis needed.
A school evaluation (age 3+)
Request one from your district in writing — the evaluation and any resulting services are free.
At home
Narrate your day in short phrases, follow your child's interests to create moments of back-and-forth, keep routines predictable, and celebrate every attempt to communicate — words, gestures, or glances. None of this is therapy, and all of it helps.
Stage 7 of 7journey map
My child was just diagnosed with autism — what do I do now?
Take a breath first. Relief and grief often arrive together — relief that the thing you saw has a name, grief for a path that looks different than imagined. Both are normal, and neither is a verdict on your child or your parenting.
The diagnosis changed the paperwork. It did not change your child.
The six steps here run in parallel, not in sequence — each moves on its own clock, and the slowest one shouldn't hold the others hostage.
Your first 90 days — a checklist
Get the full written report — and 2–3 copies
Every application that follows — coverage, EIDBI, school — will ask for it.
Secure coverage
Apply for Medical Assistance (MA). If your family's income is too high, Minnesota's TEFRA option may let your child qualify based on their own income — but TEFRA has real requirements beyond the diagnosis, so read how coverage works first.
Ask about the CMDE
If you want EIDBI-funded therapy, confirm whether your evaluation counts as a CMDE; if not, schedule one — the CMDE explained.
Contact providers and join waitlists now
Being on three lists at once is normal and expected — you can always say no later. Our intake process shows what starting looks like here.
Set up support for yourselves
The Autism Society of Minnesota runs classes and support groups; the Minnesota Autism Portal maps state services; Minnesota DHS publishes EIDBI family materials in Hmong, Somali, Spanish, Russian, and more.
“Do we have to do ABA?”
No. A diagnosis is information, not a prescription. In Minnesota, EIDBI covers four approved treatment approaches — Applied Behavior Analysis (ABA), the Early Start Denver Model (ESDM), DIR/Floortime, and RDI — and families also pursue speech, occupational therapy, and school-based services. What fits depends on your child and your goals.
We provide ABA, in center-based and in-home settings — and we'd rather you choose it than default to it.
What does an autism evaluation cost in Minnesota?
Usually less than families fear — and for many, nothing out of pocket. Coverage details, TEFRA, and what we accept live on coverage and funding.
With Medical Assistance (MA)
Diagnostic evaluations are covered — and children under 21 on MA have no copays for covered services.
With commercial insurance
Minnesota law (Minn. Stat. § 62A.3094) requires large-employer plans to cover autism diagnosis and evaluation for children under 18. Small-group and individual plans vary — call the number on your card and ask.
Through your school district
School evaluations are free — but remember they're an educational determination, not a medical diagnosis. The comparison lives on where to get evaluated.
Paying out of pocket
Varies widely by clinic. Always ask for the self-pay figure and whether a sliding scale exists.

Diagnosis questions, answered plainly
The questions Minnesota parents ask most on the way to a diagnosis — with honest answers. Have one we missed? We're happy to talk.
How long is the wait for an autism evaluation in Minnesota?
It varies a lot by clinic and by your child's age — waits of several months are common, and some families wait close to a year. Always ask each clinic for its current estimate and get on the cancellation list. Free early-intervention help can start while you wait.
Can therapy start before a diagnosis?
Early-intervention support through Help Me Grow (under 3) and school-district services (age 3+) can start with no diagnosis at all. EIDBI-funded therapy like ABA requires a diagnosis or related condition plus a CMDE — so the evaluation is the gate for that path specifically.
My child screened positive on the M-CHAT — does that mean autism?
No. The M-CHAT-R/F (Modified Checklist for Autism in Toddlers, Revised with Follow-Up) is a 20-question parent screening questionnaire for toddlers 16–30 months old. A positive screen means “follow up and evaluate” — it is never a diagnosis. What the scores mean.
What's the difference between a school evaluation and a medical diagnosis?
A school evaluation is free and determines eligibility for school services (an IEP); a medical evaluation can produce a DSM-5 diagnosis, which is what insurance and EIDBI need. Many families do both — the full comparison lives on where to get evaluated.
What tests are used to diagnose autism?
Most Minnesota evaluations combine a detailed parent interview, direct observation (often the ADOS-2), and developmental or adaptive measures like the Vineland. No single test decides it — what each one measures is decoded on the assessments page.
Is there help for children under 3?
Yes — Help Me Grow Minnesota provides free Part C early-intervention services from birth to age 3, and parents can self-refer with no diagnosis or doctor's order. It's often the fastest help available.
What does an autism evaluation cost?
With Medical Assistance, diagnostic evaluations are covered — children under 21 on MA have no copays for covered services. Minnesota requires large-employer health plans to cover autism evaluation for children under 18; other commercial plans vary — call the number on your card. School evaluations are free but educational, not medical. More on costs.
Does a diagnosis mean my child needs ABA?
No. A diagnosis opens options; it doesn't prescribe one. Minnesota's EIDBI benefit covers four approaches — ABA, ESDM, DIR/Floortime, and RDI — and school and therapy services exist alongside them. The right fit depends on your child. An honest answer.
