CAST: Childhood Autism Spectrum Test

The Childhood Autism Spectrum Test (CAST) is parent-completed questionnaire designed to assess for autism spectrum disorder (ASD) in children ages 4 to 11.

Developed by the Autism Research Centre at the University of Cambridge, the CAST consists of 39 yes/no questions about behaviors you have observed in your child. This test is not a substitute for a formal evaluation. Seek a diagnostic evaluation from a qualified clinician as early as possible if your child shows signs of autism.

If you are located in Illinois and your child is under the age of 6, please include your contact information at the end of the questionnaire for one of our clinicians to review your results. If your child would benefit from a detailed evaluation, we can help connect you with a diagnostic provider.
