The Childhood Autism Rating Scale (CARS) developed by Eric Schopler, Robert Reichier and Barbara Rochen Renner, is used in diagnosing autism. It enables a trained clinician to use a rating scale to rate indications of the Autism Spectrum Disorder(ASD).

A higher score shows a higher degree of autism, and a score of 37 to 60 typically highlights severe cases (Schopler, Reichler, & Renner, 1986).

The validity of the test is further strengthened by the high levels of diagnosis agreement between parent’s interviews, and observation (Kaat & Lecavalier, 2013).
Disadvantages and Limitations

Though it is the only test used for adolescents and adults, CARS has limitations with this population because there has not been extensive research to validate this.
Culture friendliness of CARS
CARS is especially culture friendly. The majority of tests and scales that have been developed come from the western world, and were thus, based on western cultural implications. However, CARS seems to be culture agnostic to a large extent. However, there have to be cultural expectations that should be taken into account. Some cultural practices may translate in to higher scores, but could be false (International Ethics and Special Education, 2008). For instance, making eye contact with elders is impolite in some cultures, which should be taken into account when administering
