Three screenings, three depths
Start light. Go deeper only when it feels useful. Each questionnaire is free, anonymous, and stops where you stop.
Tier 1~2 minutes
AQ-10
10 questions
The Autism Spectrum Quotient (short form) is the screening NHS clinicians most often use as a first step. It gives a quick indication of whether a fuller assessment may be worthwhile.
Best as a starting point if you're wondering whether to explore further.

RAADS-14
14 questions
A condensed version of the Ritvo Autism Asperger Diagnostic Scale, designed to screen adults — including those who have learned to mask traits — across mentalising, social anxiety and sensory reactivity.
A useful second step if AQ-10 suggested traits, or if you mask well.
