What the RAADS-R measures
The Ritvo Autism Asperger Diagnostic Scale–Revised is an 80-item self-report questionnaire designed to identify autistic traits in adults aged 16 and older. It was built specifically to catch presentations that are often missed—people who learned to mask, were assessed only in adulthood, or do not match stereotypical profiles.
Each statement is rated across your whole life, not just today. That developmental framing is what separates the RAADS-R from a generic personality quiz: autism is lifelong, so the scale asks whether a trait was present when you were young, only now, both, or never.
Four domains
- 01Social relatednessfriendship, reciprocity, and unspoken social expectations.
- 02Languageliteral interpretation, conversational rhythm, and figurative speech.
- 03Sensory-motorsound, touch, overload, and physical comfort day to day.
- 04Circumscribed interestsdeep focus, routines, and topics that are hard to set aside.
How RAADS-R scores are interpreted
Every item scores 0 to 3, for a maximum of 240. In the original validation study no non-autistic participant scored above 64, which is why 65 is widely used as the screening threshold.

Below 65
Below the screening threshold
Does not show a strong overall pattern of autistic traits, though individual traits may still be present and meaningful to you.
65 – 105
Autistic traits present
Traits are present but not consistent across every domain. This range frequently overlaps with ADHD, anxiety, burnout, and long-term masking.
106 and above
Strong pattern of traits
A profile that aligns closely with commonly reported autistic experience. Worth discussing with a clinician who assesses adults.
No single questionnaire is conclusive. Self-report scales can be affected by mood, self-awareness, and how well you have learned to mask.

Frequently asked questions
The questions people most often ask before and after taking the RAADS-R.
Start the testIs the RAADS-R test accurate?
The RAADS-R performed strongly in its international validation study, with high sensitivity and specificity in clinical samples. Accuracy is lower outside those conditions: online self-administration, co-occurring conditions, and heavy masking all affect results. Treat your score as a signal worth investigating, not a verdict.
What is a good RAADS-R score?
There is no good or bad score—only a score that does or does not cross the screening threshold. A total of 65 or more is commonly treated as an indication that a professional evaluation may be worthwhile. Below 65 does not rule autism out on its own.
How long does the RAADS-R take?
Most adults finish the 80 statements in 15 to 20 minutes. You can take longer if you need to. On this site your progress is saved in your own browser, so you can close the tab and resume later on the same device.
Is this test free and anonymous?
Yes for the core screen: there is no account required, and scoring runs in your browser. An optional paid AI report is available if you want a written analysis; choosing that sends your score summary to our API to generate the report.
Can the RAADS-R diagnose autism?
No. It is a screening instrument, not a diagnostic one. A formal diagnosis requires a qualified clinician who reviews developmental history, current functioning, and differential explanations such as ADHD, trauma, or anxiety.
Is the RAADS-R valid for women and late-diagnosed adults?
It is often recommended for exactly this group, because it asks about lifelong internal experience rather than externally visible behaviour. That said, sustained masking can still lower a score, so a result below the threshold does not close the question.
