CAST Autism Screening Tool

The questionnaire was developed by the ARC (the Autism Research Centre) at the University of Cambridge for assessing the severity of autism spectrum symptoms in children. It has proved to be a good test for screening autism spectrum disorders (ASD) and social communication problems.

At ABC we use the CAST to screen for autism-related symptoms in children ages 4 and older.
