What is Spectrum Check?
Spectrum Check is a free autism traits test for adults. It asks 20 questions about how you handle conversation, change, noise, emotions and energy today, plus two about your childhood, and counts how many of your answers lean toward autistic traits.
It's built for adults who grew up before autism screening was common, or who learned to hide their traits so well that nobody noticed, including themselves.
How to use the test
- Pick your vibe and age. The tone changes the jokes, never the score.
- Answer 10 questions about everyday life. Go with how you usually are, not how you act on your best day.
- Answer 10 about feelings, energy and childhood. If you're unsure about childhood, think about what family has told you.
- Read your result, then share it. If your score is high, use the appointment summary to start a conversation with a doctor.

What you were like as a child, which a diagnosis requiresHow we score it
Each answer that leans toward an autistic trait adds one point. Some statements count when you agree and some when you disagree, so you can't score high just by agreeing with everything. 0 to 7 is the few-traits range, 8 to 11 is some traits, and 12 or more is many traits.
The questions are original to this site and modeled on the areas covered by research screeners like the AQ-10 and RAADS-R. They have not been validated in a clinical study, so treat your score as a rough signal. Even validated screeners miss: in one study of adults referred to an autism clinic, popular questionnaires correctly flagged about 80% of autistic patients but also flagged about half of those who turned out not to be autistic.
Frequently asked questions
Can an online test tell me if I'm autistic?
No. Only a qualified clinician can diagnose autism, usually through interviews, questionnaires and your developmental history. A test like this tells you whether an assessment might be worth pursuing.
Can adults be diagnosed with autism?
Yes. Adults of any age can be assessed. CDC estimates about 2.2% of U.S. adults are autistic, and many were never identified in childhood.
Why are women diagnosed later?
Boys are identified about 3.4 times as often as girls in childhood. Women and girls are more likely to mask, and their traits are often put down to anxiety, shyness or depression first.
What is masking?
Masking means hiding or managing autistic traits to fit in: rehearsing conversations, copying others, forcing eye contact. It's exhausting over time and can make traits hard to spot, even on tests.
Do you save my answers?
No. Everything runs in your browser. Nothing you answer is sent to us or anyone else.
Does savage mode make fun of autistic people?
No. Savage mode roasts relatable habits, like rehearsing a pizza order, never autism or autistic people. The score is identical in every tone.
