Childhood Autism Spectrum Test (CAST)

The Childhood Autism Spectrum Test (CAST), also known as the Childhood Asperger Screening Test, detects Autism Spectrum Disorders (ASDs) in 5- to 11-year-old children by using a parental questionnaire to measure social and communication skills.

The CAST questionnaire contains 37 yes-or-no questions about the child’s social behaviors and communication tendencies. It also contains a separate special needs section that asks about other disorders that the child might have, for example hyperactivity or a physical disability.
