- Adults are usually assessed by a licensed psychologist or psychiatrist.
- It takes 1 to 3 appointments: questionnaires, interviews, and some structured activities.
- Self-pay often costs $1,500 to $2,500. Call your insurance first.
- Check the provider's license for free before you pay anything.
- You should get a written report and a meeting to go over it.
Who can assess you
In the US, adult autism assessments are usually done by:
Psychologists
Including neuropsychologists. The most common choice for adults. They do the testing themselves.
Psychiatrists
Medical doctors. Some do autism assessments; many refer to a psychologist for testing.
Other licensed clinicians
In some states, other licensed professionals can diagnose. Rules vary by state, so ask.
Look for someone who regularly assesses adults, not only children. Assessing a masking adult takes different experience than assessing a 4-year-old.
What happens during an assessment
The details vary by provider. Most adult assessments include these four parts.
- Forms and questionnaires
You fill these out at home before your first visit. They ask about your life now, your childhood, and your health.
- An interview about your life
The clinician asks about school, friendships, work, senses, and routines. Some also ask to talk with someone who knew you as a child, like a parent or sibling. If that's not possible, say so. Many clinicians can assess you without it.
- Structured activities
Some clinicians use a standard observation, such as the ADOS-2. It is a guided conversation with a few tasks. There are no right answers.
- Results and report
A meeting where the clinician explains what they found, followed by a written report. The report is yours to keep.
Many assessments can be done partly or fully by video. Video is fine as long as a licensed clinician does the assessment. An online quiz alone is not an assessment.
Cost and insurance
| Type | Typical self-pay price |
|---|---|
| Shorter telehealth assessment | Under $1,000 |
| Standard adult assessment | $1,500 to $2,500 |
| Also testing for ADHD or other conditions | $3,000 or more |
Insurance coverage varies a lot between plans. Don't assume testing is covered just because therapy is. Call the number on your insurance card and ask:
- "Is psychological testing for autism covered for adults on my plan?"
- "Do I need a referral or prior authorization?"
- "What will I pay if the provider is out of network?"Some providers give you a receipt called a superbill that you can send to insurance yourself.
Waitlists for adult assessments can be several months. It's fine to get on more than one list.
Before you say yes to a provider
Most people who assess adults are qualified and careful. Some aren't, and some online services sell fast "diagnoses" without a real assessment. These three checks are free and take about 5 minutes.
1Look up their license
Every state has a free online license lookup. Search [your state] psychology board license lookup and type in the clinician's name. Check that the license is active, in your state, and has no disciplinary actions.
2Get the total price in writing
Ask for the full cost before you book, including the report and the results meeting. A good provider will tell you up front.
3Ask about adults and masking
Ask how many adults they assess and how they account for masking. A clear, confident answer is a good sign.
Red flags
- Promises you'll be diagnosed before meeting you
- "Diagnosis" from an online quiz with no clinician
- Can't name the licensed clinician, or the license isn't in your state
- Won't tell you the total price up front
- Sells programs, coaching, or supplements to "treat" or "cure" autism
- Won't give you a written report
- Rules you out because you make eye contact, have a job, or have a family
Good signs
- Licensed in your state, with a name you can look up
- Total price in writing before you book
- Asks about your whole life, including masking
- Regularly assesses adults
- Gives you a results meeting and a written report
- Explains what the result means either way
- Suggests other explanations if it isn't autism
Questions to ask before you book
These are fair questions. Good providers expect them. You can copy them and send them by email if that's easier than a phone call.
- How many adults do you assess each year?You want someone who does this often.
- How do you account for masking?Listen for a specific answer, not "we'll see."
- What is the total cost, including the report?Get it in writing.
- Do you take my insurance, or provide a superbill?
- Do you need to talk to someone who knew me as a child?And what happens if that's not possible.
- Can any of it be done by video?
- Will I get a written report, and when?
- Do you also assess for ADHD?Autism and ADHD often occur together. More on this.
Getting ready
Assessments can be tiring. These make it easier and give the clinician a fuller picture.
- Write down examples from your life before the appointment, so you don't have to remember them on the spot.
- Find old school reports or report cards if you have them. Teacher comments can be useful.
- Bring headphones, sunglasses, or something to fidget with if they help. That is allowed.
- Plan nothing for the rest of the day.
Tip: on the Am I autistic? page you can tap lines that sound like you. They're saved as notes to bring here.
If the answer is no
Sometimes an assessment doesn't find autism. That does not mean your experiences aren't real.
- Ask what does explain what you're experiencing. ADHD, anxiety, or other differences can cause some of the same things.
- You can get a second opinion, especially if the clinician didn't seem experienced with adults or masking.
- Anything on this site that helps you is still yours to use.
When to get more help
If you've felt hopeless most days for 2 weeks or more, you don't need to wait for an assessment to get help. Talk to a doctor now.
If you have thoughts of not wanting to be alive, call or text 988 (US, any time). You can text if talking is too hard.
