Gilliam, J. E.




The most recent version of this test is Gilliam Autism Rating Scale (GARS 3)

The Gilliam Autism Rating Scale - Second Edition (GARS-2) is a screening test for identifying persons who have autism. Based on the definitions of autism from the American Psychiatric Association (2000) and the Autism Society of America (2003), the GARS-2 is a norm-referenced instrument that will assist examiners in the assessment of persons who have the disorder. The manual provides basic information about autism, instructions for administering and scoring the test, procedures for interpreting the results, technical information about the instrument, and a list of discrete target behaviors for applied behavior analysis research. This chapter provides background information about autism and an overview of the GARS-2.
