In short: Online autism tests such as the AQ-10 and RAADS-R are screening questionnaires. They can suggest whether autistic traits are worth exploring, but only a registered professional can diagnose autism.

We link to the official versions of these autism tests rather than copying them, because their creators restrict reproduction. Here is what each one is and how to interpret it.
AQ-10 (Autism Spectrum Quotient, 10 items)
Developed at the Autism Research Centre (University of Cambridge) and recommended by the UK’s NICE as a quick adult screener. It has 10 statements; a score of 6 or more suggests a referral for specialist assessment may be appropriate. Get the official AQ-10 from the ARC.
RAADS-R (Ritvo Autism Asperger Diagnostic Scale – Revised)
An 80-question self-report scale covering language, social relatedness, sensory-motor and circumscribed interests. It is longer and more detailed than the AQ-10 and is often used by clinicians as part of adult assessment. A total of 65 or more is the published threshold suggesting autistic traits.
AQ test vs RAADS-R: which should I take?
| Test | Length | Best for |
|---|---|---|
| AQ-10 | 10 items, 2 minutes | A quick first check |
| AQ-50 | 50 items | A fuller picture of traits |
| RAADS-R | 80 items, 20–30 minutes | Detailed self-reflection before an assessment |
Are online autism tests accurate?
They are useful but imperfect. People who mask, women, and people with anxiety or trauma may score in misleading ways. Use results as a conversation starter with a professional.
Is there an AuDHD test?
No single validated AuDHD test exists. Screen for ADHD with our free ASRS self-screen and for autism with the tools above.
