The CARS (Childhood Autism Rating Scale) is a widely used tool by clinicians and researchers to assess the severity of autism spectrum disorder (ASD) in children. Its purpose is to provide a standardized measure that aids in diagnosis, treatment planning, and tracking developmental progress over time. The availability of the CARS in PDF format makes it accessible for professionals, educators, and parents who seek a reliable and straightforward assessment instrument. In this comprehensive guide, we will explore the origins of the CARS, its structure, interpretation, and how to access and utilize the CARS autism rating scale PDF effectively.
Understanding the CARS Autism Rating Scale
What is the CARS?
The Childhood Autism Rating Scale (CARS) was developed in the 1980s by Eric Schopler, Robert J. Reichler, and Barbara C. Rochen Renner. It is designed to distinguish children with autism from those with other developmental disorders and to gauge the severity of autism symptoms. The scale encompasses a comprehensive evaluation of behaviors associated with autism, making it a valuable tool in both clinical and research settings.
Key Features of the CARS
- Behavioral observation-based assessment
- Rated on a 15-item scale covering various aspects of behavior
- Provides a quantitative measure of autism severity
- Easy to administer with minimal training required
- Available in multiple formats, including PDF for easy access and distribution
Structure of the CARS
Items Covered in the CARS
The CARS evaluates 15 different behavioral domains, each representing core symptoms of autism. These include:
- Relating to people
- Impairment in peer relationships
- Echolalia and related behaviors
- Body use
- Object use
- Adaptation to change
- Visual responses
- Taste, smell, and touch responses and use
- Fear and nervousness
- Communication
- Laughter and enjoyment
- Gross motor skills
- Fine motor skills
- Verbal responses
- Activity level
Each item is rated based on observations and/or reports, typically by a trained evaluator.
Scoring System
The CARS uses a 7-point ordinal scale for each item:
- 1: Typical behavior
- 2: Mildly abnormal
- 3: Slightly abnormal
- 4: Clearly abnormal
- 5: Severely abnormal
- 6: Consistent with autism
- 7: Severe autism
The evaluator assigns a score for each item, and the sum of these scores provides an overall severity rating.
Interpreting CARS Scores
Severity Categories
Based on the total score, the child's autism severity is classified into categories:
- 15-30: Non-autistic or typical development
- 31-36.5: Mild to moderate autism
- 37-60: Severe autism
This classification helps clinicians determine the intensity of intervention needed and monitor changes over time.
Using the Scores for Treatment Planning
The detailed item scores enable a nuanced understanding of a child's specific strengths and challenges. For example:
- High scores in 'relating to people' and 'peer relationships' may indicate areas requiring social skills interventions.
- Elevated scores in 'visual responses' or 'body use' can guide sensory integration therapies.
- Repeated assessments using the CARS can track progress and the effectiveness of interventions.
Advantages of the CARS
Reliability and Validity
The CARS has demonstrated good reliability and validity across diverse populations. Its standardized format ensures consistency in assessment and comparability across different evaluators.
Ease of Use
The scale is straightforward to administer, often taking around 15-20 minutes. It requires minimal training, making it accessible for various professionals, including psychologists, speech therapists, and special educators.
Comprehensive yet Practical
While covering multiple domains, the CARS remains concise and practical, providing a comprehensive overview without being overly burdensome.

Additional Resources and Support
Training and Certification
While the CARS is designed to be straightforward, professional training can improve reliability. Some organizations offer workshops and certification programs for clinicians.
Complementary Assessment Tools
The CARS can be supplemented with other tools such as:
- ADOS (Autism Diagnostic Observation Schedule)
- ABC (Aberrant Behavior Checklist)
- Vineland Adaptive Behavior Scales
These provide additional insights into a child's developmental profile.
Parent and Caregiver Involvement
Involving parents or caregivers in the assessment process can enrich the information gathered, especially in areas like communication and daily routines.
