Screen for Autism in Children 4 and Up

Childhood Autism
Spectrum Test (CAST)

The Childhood Autism Spectrum Test or CAST (formerly the “Childhood Asperger’s Syndrome Test”) is a parent questionnaire that assesses for symptoms of autism and social communication problems.

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.

While diagnosis of typical autism will usually occur in early childhood, Aspergers syndrome and other pervasive developmental disorders may be missed until much later.

The Childhood Autism Syndrome Test (CAST) allows detection of such cases which may need further assessment.
