Autism Test (Adult)
A confidential self-assessment using the complete Autism-Spectrum Quotient (AQ), the 50-statement questionnaire developed by Simon Baron-Cohen and colleagues at Cambridge and used in autism research worldwide. You get a full 0 to 50 score, a breakdown across five trait domains, an affirming plain-language interpretation, and an optional in-depth personalized report to keep or bring to a clinician.
Autism Test (Adult) is a free, confidential 50-question self-assessment, based on the full 50-question AQ. It takes about 8 minutes, runs entirely in your browser, and gives you a plain-language score across 4 interpretation bands plus an optional in-depth report. It is an educational screening, not a diagnosis.
The complete AQ, read through an affirming lens
The Autism-Spectrum Quotient looks at everyday ways of thinking, noticing, and relating across five domains where autistic adults often differ from non-autistic adults. It measures traits, not worth, and being autistic is a difference in how a mind works, not something broken that needs fixing.
The full Autism-Spectrum Quotient
All fifty statements from the original AQ (Baron-Cohen et al., 2001), not a shortened quiz. Each answer scores one point when it falls in the autistic direction; we handle the scoring direction of every item internally.
Five trait domains
Ten statements each on social skill, attention switching, attention to detail, communication, and imagination. Your result shows a score for every domain, so you can see where your traits cluster rather than just a single number.
The research thresholds
Scores of 26 or more are the threshold used in clinical research to flag an elevated autistic-trait profile, and 32 or more was the original study's cutoff, reached by 80 percent of autistic adults. Most adults without autism score between 15 and 22.

How scoring works
Answers are scored 0–50 in total. Your result falls into one of 4 bands:
| Score | Band | What it suggests |
|---|---|---|
| 0–21 | In the typical range | Your AQ score falls in the range where most adults land. In the original research, most adults without autism scored between 15 and 22, so a score of 21 or below reflects a fairly typical mix of traits on this measure. |
| 22–25 | Slightly elevated | Your score is a little above where most adults land, though below the threshold clinical researchers use to flag an elevated autistic-trait profile. This is a common place to land, and your domain scores will tell you more than the total. |
| 26–31 | Elevated autistic traits | Your score is at or above 26, the threshold used in clinical research to identify adults for whom a fuller autism assessment may be worth considering. Many autistic adults score in this range. This is a signal worth exploring, not a verdict. |
| 32–50 | Strong autistic-trait profile | Your score is 32 or above, the threshold Baron-Cohen and colleagues used in the original AQ research. In that study, 80 percent of autistic adults scored in this range, while very few non-autistic adults did. Your answers describe a strong autistic-trait profile. |
Methodology & sources
This test reproduces the complete Autism-Spectrum Quotient (AQ), the fifty-item self-report questionnaire developed by Baron-Cohen and colleagues (2001) at the University of Cambridge. Each statement is answered on a four-point agreement scale and scored as a single point when the answer falls in the autistic direction: twenty-four items score a point for agreeing and twenty-six for disagreeing, and we handle that direction internally for every item. The total runs from 0 to 50 across five domains of ten items each: social skill, attention switching, attention to detail, communication, and imagination. In the original study, most adults without autism scored between 15 and 22, while 80 percent of autistic adults scored 32 or more, the original cutoff. Later clinical research (Woodbury-Smith et al., 2005) found that a lower threshold of 26 or more works well in practice for deciding when a fuller assessment is worth considering. Item wording has been lightly adapted for readability while preserving the meaning of the validated instrument.
For readability we present the fifty statements grouped into their five domains, whereas the original questionnaire interleaves them in a fixed mixed order. Every item keeps its published domain assignment and scoring direction, so the domain scores and the 0 to 50 total are calculated exactly as in the published instrument.
This screening is provided for education and self-reflection. The AQ measures autistic traits in the general population; it is not a diagnostic instrument, and no score can tell you whether you are autistic. A formal autism assessment is carried out by a qualified clinician using a structured developmental history and direct observation. We present the result in affirming, strengths-aware language, because autism is a difference in neurology, not a deficit.

Autism Test (Adult) FAQ
What is the AQ (Autism-Spectrum Quotient)?
The AQ is a fifty-statement self-report questionnaire developed by Simon Baron-Cohen and colleagues at Cambridge in 2001. It measures autistic traits across five domains: social skill, attention switching, attention to detail, communication, and imagination. It is one of the most widely used autism screening tools in research and clinical practice, and this test uses the complete version, not a short form.
What is a normal AQ score?
In the original research, adults without autism averaged around 16, and the large majority scored 21 or below. Scores of 26 or more are considered elevated in clinical research, and 32 or more was the original study's threshold, reached by 80 percent of autistic adults. Everyone has some of these traits, so a score above zero is entirely normal.
What score suggests I should consider an assessment?
Clinical research suggests that a score of 26 or more is a reasonable point at which a fuller conversation about assessment may be worthwhile, and 32 or more was the original, stricter cutoff. A lower score does not rule autism out, especially for women and people who mask well. If you strongly relate to autistic experiences regardless of the number, that is worth taking seriously.
How is this different from the AQ-10?
The AQ-10 is a ten-item short form drawn from this questionnaire, designed as a quick referral aid. The full AQ you take here uses all fifty original statements, which gives a more detailed picture, including a score for each of the five trait domains rather than a single brief total.
Is this test a diagnosis?
No. It is for education and self-reflection only. An autism diagnosis is made by a qualified clinician through a structured developmental history and observation. If your result resonates, a screening result can be a useful thing to bring to that conversation.
Is being autistic a disorder?
Autism is a neurotype, a different way of thinking, sensing, and relating, with real strengths as well as challenges. Many autistic adults find that understanding themselves through this lens is clarifying and affirming rather than something to be fixed.
Is the test really confidential?
Yes. It runs entirely in your browser. Your answers are never sent to a server, never stored, and never linked to you. No account is needed.
