The Autism Spectrum Quotient (AQ) is a self-assessment questionnaire designed to measure autistic traits in adults (age 16+). It was first published in the paper The Autism-Spectrum Quotient (AQ): Evidence from Asperger Syndrome/High-Functioning Autism, Males and Females, Scientists and Mathematicians (Baron-Cohen et al., 2001).
This online version lets you explore how autistic characteristics may appear in daily life. If you’re interested in observing these traits in others, try our companion Autism Test for Someone Else. Both tools are for reflection and learning – not for diagnosis.
Autism-Spectrum Quotient (AQ-50)
Please answer all questions. Choose one option in each row.

Scoring and interpretation
- Scoring range: 0-50
- Threshold score: 26
- Scores of 26 or higher suggest more autistic traits; lower scores indicate fewer traits.
- 79.3% of autistic people score 32 or higher.
- Most non-autistic males score about 17 on average.
- Most non-autistic females score about 15 on average.
These results are only an indication. A higher score does not mean you are autistic – it simply reflects a pattern of traits often associated with autism. Everyone may have some autistic characteristics; this tool helps you understand where you might fall on that spectrum.
Note: These tools are screening instruments, not diagnostic tests.
If your results concern you, it may be helpful to speak with a qualified clinician who has experience with adult autism assessments. Understanding yourself or someone else better is a good step toward self-love, connection, and support.
