COOLIDGE AUTISTIC SYMPTOMS SURVEY Toddler Version (CASS-T)

The CASS is a 39-item, parent-as-respondent inventory that has been designed to assess the Autism Spectrum Disorder according to the criteria in the new DSM-5. It is appropriate for children ages 1 year old to 3 years old, and it has been empirically demonstrated to be able to diagnose children in the Autism Spectrum from mild to severe and to be able to distinguish between children in the Autism Spectrum from purportedly normal children. The CASS-T is highly reliable and has been validated on samples of children with established diagnoses of Autism (mild to severe).
