ATEC Guide
The ATEC is a clear, data-centered way to track your child’s progress
When your child has complex needs, guessing isn’t enough — and trying to track everything mentally can feel overwhelming.
You deserve a simple, research-aligned way to understand what’s helping your child and where to focus next.
That’s why we created this family-friendly ATEC Guide — to help you confidently use the Autism Treatment Evaluation Checklist, a trusted tool developed by the Autism Research Institute (ARI).
The ATEC was created under the leadership and legacy of:
• Dr. Bernard Rimland, Ph.D. — ARI Founder.
• Dr. Stephen M. Edelson, Ph.D. — ARI Executive Director & Chief Science Officer, leading ARI since 2006.
We are honored to share this resource with permission from Dr. Stephen M. Edelson to help families access and understand this important tool.
