Frequently asked questions at our King of Prussia ABA therapy center
What is ABA therapy, and how does it work?
Applied behavior analysis (ABA) therapy is an evidence-based treatment for children diagnosed with autism that uses positive reinforcement and individualized teaching to help children build new skills. At Action Behavior Centers – King of Prussia, Pennsylvania, our ABA programs are tailored to each child, focusing on improving their communication, social skills, and daily living skills in a supportive and engaging environment.
Does my child need an autism diagnosis before starting ABA therapy in King of Prussia, PA?
Yes, a formal autism diagnosis is required before starting ABA therapy in King of Prussia, Pennsylvania. A diagnosis is needed to access early intervention services, qualify for insurance coverage, and receive autism support through school systems. Action Behavior Centers offers no-cost autism evaluations at our King of Prussia location, including the ADOS-2 and other diagnostic tools, to help families get started as quickly as possible.
My child’s doctor said they might just be delayed and suggested waiting to test for autism. Should I wait?
Waiting can mean missing important opportunities for early intervention. ABA therapy is most effective when started early, ideally between 18 months and 5 years. Getting an early autism evaluation in the Philadelphia area allows your child to begin services sooner and start working on communication, behavior, and social interaction during critical developmental years.

View all FAQsWill my child be sitting at a table all day during ABA therapy?
No way! At ABC, learning happens through a variety of engaging activities. While table time can be part of learning school readiness skills, children also enjoy:
- Circle Time with therapists and peers
- “Eats and Crafts” spaces for hands-on activities
- Group exercise, sensory rooms, and play-based learning
Therapy is designed to be fun, active, and motivating.
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 internal 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. See more of our outcomes research here.
I think my child is showing signs of autism. Should I wait to get my child evaluated?
It’s understandable to want to trust that your child will catch up on their own, but waiting to seek an autism diagnosis can mean missing important chances for early intervention. Getting an early autism diagnosis lets your child start therapies like ABA sooner, which can improve their communication and interactions with others. Starting ABA therapy early, ideally between 18 months and 5 years, gives your child the best chance to grow and reach their goals.
Who can diagnose autism?
In the U.S., autism is diagnosed by qualified medical and mental health professionals through a comprehensive evaluation. This process may include direct observation, developmental history, caregiver interviews, and standardized diagnostic tools to determine whether a child meets criteria for autism spectrum disorder (ASD). Many children can be evaluated as early as age 2.
Professionals who may diagnose autism include:
- Developmental pediatricians
- Child psychologists or neuropsychologists
- Child psychiatrists
- Pediatric neurologists
BCBAs may support the evaluation process, but a formal autism diagnosis is typically made by one of the specialists listed above.
Screening tools, such as the M-CHAT-R or CAST can help identify signs that a child may be at risk for autism. However, a full autism evaluation is required to make a formal diagnosis.
