Who it is for
Adults who suspect they may be autistic—especially those who were not assessed in childhood—often find structured self-screens useful before booking a clinical evaluation. The language on this site is written for readers across the United States, United Kingdom, and European Union.
How scoring is commonly read
Each item is scored from 0 to 3. Many published references treat a total of 65 or higher as a screening threshold worth discussing with a professional. Domain totals show where traits cluster.
