Very happy with ABC and all the therapists. They are all so sweet and nice, always willing to help in any way they can. My son loves going to "school" everyday and loves his therapists so much. I always leave with a peace of mind knowing they are taking good care of him and as a parent, that is the most important thing. We are so lucky to be part of the ABC family. I cannot recommend this place enough, absolutely happy with everyone here.
The ABA therapy provided here has been a game changer for my son, who in his own words said "I've learned how to make friends and finally enjoy school." The staff are delightful and knowledgeable, and patiently worked with us as we navigated our own journey through the world of ABA. The staff at ABC gave our family the tools we needed to improve our son's life and ours. It's definitely a team effort and parents need to be willing to put in the investment of learning too, but it's absolutely worth it. We even miss coming here as we had such positive interactions with the staff! Thank you, ABC!

The M-CHAT
Children 3 and younger
The Modified Checklist for Autism in Toddlers (M-CHAT) can help parents receive an autism risk score for their child. Parents or other caregivers who know the child best answer a few questions about how the child usually behaves. The resulting risk score can help guide the next steps.
Take the M-CHATThe CAST
Children 4 and older
Parents of older children complete the Childhood Autism Spectrum Test (CAST), which asks questions about specific autism symptoms, such as social interaction issues and communication challenges.

Frequently asked questions
View all FAQsWho can diagnose autism in children?
Only a qualified healthcare professional—such as a developmental pediatrician, child psychologist, or pediatric neurologist—can make an official diagnosis.
Screeners like the M-CHAT-R or CAST can show risk, but a full diagnostic evaluation (such as the ADOS-2 or IDE) is required for a formal diagnosis. At ABC, evaluation results are sent directly to your child’s doctor for review.
What is the best treatment for autism?
At Action Behavior, we provide applied behavior analysis (ABA) therapy, a gold standard treatment for autism. ABA therapy for autism is evidence-based, which means it has been tested and shown to be effective through multiple scientific studies.
Our data show that children with autism who require comprehensive ABA therapy (25 or more hours per week) experience, on average, an 86% reduction in challenging behaviors such as aggression, elopement, property destruction, and self-injury. Most of this progress happens within the first year of treatment. Even as therapy hours are gradually reduced by about 20% over time, children continue to show lasting improvements.
What is applied behavior analysis (ABA) therapy, and how does it work?
Applied behavior analysis (ABA) therapy is a gold standard in care for children diagnosed with autism spectrum disorder (ASD). It helps children build practical skills and reduce behaviors that may make learning harder. Through ABA therapy, children can improve communication, develop self-care routines, and better manage emotions.
At Action Behavior Centers (ABC), our Board Certified Behavior Analysts (BCBAs) and Registered Behavior Technicians (RBTs) use positive reinforcement and individualized strategies to support growth. Families are active partners in therapy, working with our clinical team to set goals and track progress.
