Gilliam Autism Rating Scale (GARS)
The GARS is a behavioral checklist that helps identify persons with an autism spectrum disorder. The
checklist queries behavioral characteristics related to autism across four areas. These areas include
stereotyped behaviors, communication, social interaction, and developmental disturbances. Scores from the
GARS are estimates of the likelihood that the individual is autistic. Subtest standard scores of 8 to 12 or
Autism Quotient of 90 to 110 are within the average range for subjects with autism and indicative of autism.
Percentile ranks are based on a normative sample of individuals with autism For example, if a score falls at
the 63rd percentile, this indicates that 6% of the subjects in the normative sample fall below that score and
demonstrate fewer characteristics of autism.
The Gilliam Autism Rating Scale (GARS) was completed by STUDENT’S
********* teacher, ********* and/or parent. The results of the GARS completed by *********’s *********
are reported below:
Subtest
Stereotyped Behaviors
Communication
Social Interaction
Standard Score
Percentile
Probability of Autism
Developmental
Autism Quotient
According to the results of the GARS, the likelihood that STUDENT is autistic is in the ********* range across
all domains.
The Autism Quotient is based o the symptomatic behaviors of autism across all subtests and is the best
estimate of an individual’s behavior. STUDENT Autism Quotient of ********* is within the ********* range.
According to the GARS results,
Within the area of stereotyped behaviors, STUDENT’S teacher reported ********* (more, fewer, similar)
behaviors that are typical of autism spectrum disorders. He/she reported that he/she (frequently/sometimes):
*********
Within the area communication, ********* (frequently, sometimes): *********
In the area of Social Interaction, ********* (frequently/sometimes): *********
