Product Details

CARS2 has been revised to cover the entire autism spectrum, including Asperger’s Syndrome.

Benefits

  • Integrate diagnostic information.
  • Determine functional capabilities.
  • Provide feedback to parents.
  • Design targeted interventions.

Features

CARS2 includes enhancements that make the test more responsive to individuals on the high-functioning end of the autism spectrum — those with average or higher IQ scores, better verbal skills, and more subtle social and behavioral deficits.

  • Standard Version Rating Booklet: for use with individuals younger than age 6 and those with communication difficulties or below average estimated IQs.
  • High Functioning Individuals Rating Booklet: use to assess verbally fluent individuals ages 6 and older, with IQ scores above 80.
  • Questionnaire for Parents or Caregivers: an unscored scale that gathers information for use in making Standard and High Functioning ratings.
