The CASD offers a quick, valid means of screening for, and diagnosing, children with Autism, regardless of age, IQ or Autism severity. It consists of a comprehensive list of 30 symptoms of Autism, scored as present (either currently, or in the past) or absent, based on a semi-structured interview with the parent; information from the child’s teacher or child care provider; observations of the child, and other available records.
Studies show the CASD differentiates children with Autism from those with ADHD with 99.5 percent accuracy, and from typical children with 100 percent accuracy. It is equally effective in identifying children who have Autism and normal, or below normal, intelligence.
