Childhood Autism Rating Scale

The Childhood Autism Rating Scale (CARS) is a behavior rating scale intended to help diagnose autism. CARS was developed by Eric Schopler, Robert J. Reichler, and Barbara Rochen Renner. The scale was designed to help differentiate children with autism from those with other developmental delays, such as intellectual disability.

Although there is no gold standard among rating scales in detecting autism, CARS is frequently used as part of the diagnostic process.^[1]

Evaluation criteria[edit]

The CARS is a diagnostic assessment method that rates individuals on a scale ranging from normal to severe, and yields a composite score ranging from non-autistic to mildly autistic, moderately autistic, or severely autistic. The scale is used to observe and subjectively rate fifteen items.

• adaptation to change
• visual response
• listening response
• taste-smell-touch response and use
