Understanding the Gilliam Autism Rating Scale (GARS)
What Is GARS?
The Gilliam Autism Rating Scale (GARS) is a standardized instrument developed by Dr. James E. Gilliam. It was created to assist in identifying and diagnosing autism spectrum disorder in children aged 3 to 22 years. The scale evaluates behaviors that are characteristic of autism, such as social interaction deficits, communication challenges, and repetitive behaviors.
Purpose of GARS
The main objectives of GARS include:
- Screening for autism in various settings, including schools and clinics
- Assisting in the diagnostic process
- Monitoring behavioral changes over time
- Planning individualized interventions
The scale is designed to be user-friendly for professionals and caregivers, providing a structured approach to assess autism-related behaviors.

Components of the Gilliam Autism Rating Scale PDF
Structure of the Scale
The GARS is typically available in a PDF format, which includes:
- Introduction and Instructions: Guidelines on how to administer and score the assessment
- Behavioral Items: A list of behaviors associated with autism, categorized into subscales
- Scoring Sheets: Sections where observers record the frequency or severity of behaviors
- Interpretation Guidelines: Normative data and scoring interpretations to help determine autism severity
Subscales of GARS
The scale assesses behaviors across four main subscales:
1. Stereotyped Behaviors: Repetitive movements and interests
2. Communication: Verbal and non-verbal communication skills
3. Social Interaction: Ability to engage with peers and adults
4. Developmental Disorders: Broader developmental delays often associated with autism
Each subscale contains specific items rated on a Likert-type scale, which reflects how frequently or intensely the behavior occurs.

Interpreting GARS PDF Results
Scoring Methodology
The GARS scoring involves:
- Rating each item based on observed or reported behaviors
- Summing the scores within each subscale
- Comparing the total scores to normative data
Scores are then categorized into:
- Non-ASD: Behaviors are within typical ranges
- Weak Autism Spectrum Disorder: Mild symptoms
- Medium Autism Spectrum Disorder: Moderate symptoms
- High Autism Spectrum Disorder: Severe symptoms
Understanding the Severity Levels
The scale provides cut-off scores to help interpret the severity of autism:
- Low scores suggest minimal autism-related behaviors
- High scores indicate significant symptoms warranting comprehensive diagnosis and intervention
Accurate interpretation is crucial for determining appropriate support strategies and planning tailored therapies.

Comparison with Other Autism Assessment Tools
While GARS is a valuable tool, it is often used alongside other assessments to ensure comprehensive diagnosis:
- Autism Diagnostic Observation Schedule (ADOS): A semi-structured, standardized assessment conducted through direct observation
- Autism Diagnostic Interview-Revised (ADI-R): A structured interview with caregivers covering developmental history
- Social Communication Questionnaire (SCQ): A screening tool for social communication behaviors
Advantages of GARS:
- Quick to administer
- Suitable for a wide age range
- Useful for screening and monitoring
Limitations of GARS:
- Relies on observer or caregiver reports, which may be subjective
- Not a standalone diagnostic tool; should complement clinical judgment and other assessments
