The Childhood Autism Rating Scale 2nd ed. (CARS2) helps to identify children with autism and determine symptom severity through quantifiable ratings based on direct observation, for children aged 2 years and above.
It includes two 15-item rating scales completed by the clinician (each designed for a different population-Standard and High Functioning); and an unscored Parent/Caregiver Questionnaire, that gathers information for use in marking the Standard and High Functioning ratings.
The *CARS2 High Functioning Version Rating Booklet * includes 15 items, addressing these functional areas:
The clinician rates the individual on each item, using a 4-point response scale.
Rating values for all items are summed to produce a Total Raw Score. Each form includes a graph that allows you to quickly convert the Total Raw Score to a standard score or percentile rank.
The items on the High Functioning form have been modified to reflect current research on the characteristics of people with high-functioning autism or Asperger's Syndrome.
