On-Line Screeners for Autism Spectrum Disorder: Children, Adolescents and Adults

I have been asked again to provide some useful on-line screeners for parents. There are only a few that are really worth using. Below are autism screeners for children, adolescents and adults:

Autism Screening Tool for Children ages 3-11

For children ages 3-11, I would suggest The Childhood Autism Spectrum Test (CAST)  Here is a link to an on-line version:


Autism Screening Tool for Teens ages 12-15

For teens I would suggest The Adolescent Autism Spectrum Quotient (AQ). Here is a link to an on-line version:


Autism Screening Tool for Adults Ages 16+

For adults I would suggest the The Adult Autism Spectrum Quotient (AQ)
