AUTISM SPECTRUM
• Binary classification studies indicate that the GARS-3 is able to accurately dis- criminate children with autism spectrum disorder from children without autism (i.e., sensitivity = .97, specificity = .97, ROC/AUC = .93). • Confirmatory and exploratory factor analyses demonstrate the theoretical and empiri- cal validity of the subscales. • Other validity evidence is provided in the manual. NOW AVAILABLE! ONLINE ADMINISTRATION, SCORING, AND REPORT SYSTEM Access to the GARS-3 Online Administration, Scoring, and Report System is now included with the purchase of each GARS-3 Complete Kit and with the purchase of every replacement pack of Summary/Response Forms. It can also be purchased as a stand-alone product. This administration, scoring, and report system was designed as a quick, efficient tool for (a) completing ratings online; (b) entering test session results; (c) converting subscale item scores or total raw scores into scaled scores and percentile ranks; (d) generating Autism Index scores and percentile ranks; (e) obtaining a score summary and narrative report; (f) saving or printing examinee responses; and (g) gen- erating treatment goals and objectives based on the item performance of the student.

GARS-3: Gilliam Autism Rating Scale–Third Edition James E. Gilliam AGES: 3 through 22
TESTING TIME: 5 to 10 minutes ADMINISTRATION: Individual
The Gilliam Autism Rating Scale , now in its third edition, is a widely used instrument for the assessment of autism spectrum disorder. The GARS-3 helps teachers, parents, and clinicians in identifying autism in individuals and estimating its severity. Items on the GARS-3 are based on the 2013 diagnostic criteria for autism spectrum disorder adopted by the APA and published in the Diagnostic and Statistical Manual of Mental Disorders–Fifth Edition (DSM-5) . The GARS-3 yields standard scores, percentile ranks, severity level, and probability of autism. The instrument consists of 56 clearly stated items describing the characteristic behav- iors of persons with autism. The items are grouped into six subscales: Restrictive/ Repetitive Behaviors, Social Interaction, Social Communication, Emotional Responses, Cognitive Style, and Maladaptive Speech. FEATURES OF THE GARS-3 • Items and subscales reflect DSM-5 diagnostic criteria for autism spectrum disorder. • Forty-four new items were added to the GARS-3. • All six subscales have been empirically determined to be valid and sensitive for iden- tification of children with ASD. • Normative data ( N = 1,859) were collected in 2010 and 2011. • Demographic characteristics of the normative sample are keyed to those reported by U.S. Bureau of the Census, 2011. • An interpretation guide in the Examiner’s Manual allows the examiner an easy and efficient method for assessing the probability of autism spectrum disorder and the severity of the disorder. RELIABILITY AND VALIDITY • Internal consistency (content sampling) reliability coefficients for the subscales exceed .85 and for the Autism Indexes exceed .93. • Test–retest (time sampling) reliability coefficients exceed .80 for subscales and .90 for the Autism Indexes. • Interrater reliability intraclass coefficients exceed .80 and .84 for the Autism Indexes. • Correlations of the GARS-3 scores with those of other well-known diagnostic tests for autism are large or very large in magnitude. • All-new validity studies show that the test results are valid for a wide variety of sub- groups, as well as for the general population.
