The GARS-2, a revision of the popular Gilliam Autism Rating Scale, is a norm-referenced instrument that assists teachers, parents, and clinicians in quickly identifying and diagnosing autism and estimating its severity in children, adolescents, and young adults.

Gathers diagnostically significant information

• Consists of 42 clearly stated items describing behaviors characteristic of persons with autism.
• Items are grouped into three subscales—Stereotyped Behaviors, Communication, and Social Interaction.
• Structured parent interview form helps you gather diagnostically significant information about the individual’s development during early childhood.

Improvements result in easier interpretation

• Normed on a sample of 1,107 individuals with autism from 48 states.
• Guidelines for interpreting subscale scores and the Autism Index (formerly the Autism Quotient) have been updated.
• Strong psychometric characteristics were confirmed through studies of the test’s reliability and validity.
• A separate booklet, Instructional Objectives for Children Who Have Autism, is included in the test kit to assist in the development of instructional goals and objectives based on the results from the GARS-2.
