Understanding the Autism Treatment Evaluation Checklist (ATEC)

Autism spectrum disorder (ASD) is a developmental disorder characterized by challenges with social interaction, communication, and by restricted and repetitive behavior. Recognizing the need for effective tools to evaluate and measure the effectiveness of autism treatments, the Autism Treatment Evaluation Checklist (ATEC) was developed. 

What is the Autism Treatment Evaluation Checklist (ATEC)?

The ATEC is a free assessment tool designed specifically for tracking the progress and evaluating the effectiveness of treatments in individuals with autism. Developed by Bernard Rimland and Stephen Edelson of the Autism Research Institute, the ATEC is not a diagnostic tool but rather a means for assessing how an individual with autism is progressing over time. It spans a wide array of behaviors and skills, offering a comprehensive look at an individual’s abilities and areas of challenge.

The Purpose of ATEC

The ATEC’s primary purpose is to facilitate the evaluation of various autism treatments’ effectiveness. It allows caregivers, parents, and professionals to monitor changes in behavior, communication abilities, social skills, and physical health, helping to identify which interventions are most beneficial for the individual with autism.

How to Complete the ATEC

Completing the ATEC involves responding to questions across four subtests:

1. Speech/Language/Communication: Evaluates verbal and non-verbal communication skills.

2. Sociability: Looks at the ability to engage in social interactions and form relationships.

3. Sensory/Cognitive Awareness: Assesses responses to sensory stimuli and cognitive abilities.

4. Health/Physical/Behavior: Addresses physical health and behaviors, including sleep patterns and eating habits.

The checklist is designed to be filled out by those who know the individual with autism well, typically parents or primary caregivers. It is available online, can be completed in approximately 10-20 minutes, and provides immediate scoring results.

Benefits of the ATEC

– Cost-effective and Accessible: As a free and easily accessible tool, the ATEC is a valuable resource for families and professionals across the globe.

– Measurable Outcomes: It offers quantifiable data that can be used to assess the impact of treatments over time.

– Tailored Treatment: By pinpointing specific areas of difficulty, the ATEC helps in customizing interventions to meet the unique needs of each individual with autism.

– Supports Research: The data collected can support research efforts, aiding in the identification of effective treatments and advancing understanding of autism.

 Limitations of the ATEC

– Not a Diagnostic Tool: It is important to note that the ATEC is not intended for diagnosing autism or determining its severity. It’s an evaluative tool, not a substitute for professional diagnosis or assessment.

– Subjective Responses: The tool’s reliance on subjective observations can affect the accuracy of responses.

– Cultural and Linguistic Differences: The ATEC may not fully account for the influence of cultural or linguistic differences on responses.

– Potential for Missing Subtle Changes: Some minor changes or improvements may not be captured by the ATEC scores, especially in aspects not covered by the checklist.


Developed by Bernard Rimland and Stephen Edelson at the Autism Research Institute, the Autism Treatment Evaluation Checklist (ATEC) is an invaluable resource for tracking the efficacy of autism treatments. While it has its limitations, such as subjectivity and not being a diagnostic tool, the ATEC’s benefits in customizing and evaluating treatment approaches are significant. It stands as a testament to the importance of tailored, individualized care in the treatment of autism, serving as a critical component of a holistic assessment and treatment planning process.
