Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R)

For each statement, the RAADS-R asks not just whether it's currently true, but also whether it was true before age 16 -- since autistic traits develop in childhood, even when they're only recognized in adulthood. This test is meant for adults (16+) and takes 15-30 minutes depending on reading speed.

This test is a self-exploration tool, not a clinical or diagnostic assessment of autism. Both autistic and non-autistic people can fall above or below the thresholds mentioned. Whether an autism spectrum condition is present can only be determined through a professional evaluation by specialized psychologists or doctors.
