Frequently asked questions at ABC Academy in Thornton, Colorado
What is ABA therapy, and how does it work?
Applied behavior analysis (ABA) therapy is a research-backed approach to helping children with autism develop essential life skills while reducing challenging behaviors. Using positive reinforcement and play-based strategies, ABA helps children grow in areas such as communication, social interaction, and independence.
At ABC Academy in Thornton, our ABA therapy programs are personalized to each child’s unique needs.
Does my child need an autism diagnosis before starting ABA therapy in Thornton?
Yes. A formal autism diagnosis is required to begin ABA therapy in Thornton. This diagnosis is also necessary for insurance coverage and to qualify for educational support. Action Behavior Centers provides no-cost autism evaluations, including the ADOS-2 and comprehensive diagnostic evaluations (CDEs), to help families access the care their child needs.

The doctor said my child's development is delayed and suggested waiting to test for autism. Is that a good idea?
It’s natural to hope your child will catch up on their own, but waiting to seek an autism diagnosis in Thronton can delay access to early autism intervention services. An early autism diagnosis allows your child to start therapies like ABA sooner, which can improve communication, social skills, and behavior. Starting therapy between 18 months and 5 years gives your child the best opportunity to thrive.

View all FAQsWill my child be sitting at a table all day during ABA therapy?
No. At ABC, learning happens through a variety of engaging activities. While table time can be part of school readiness, children also enjoy:
- Circle Time with songs and group learning
- “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.
Is ABA therapy effective for autism?
Yes! Every autistic child is unique, and some children experience more significant progress with ABA therapy than others. However, studies show that children who receive two or more years of intensive behavioral interventions, including ABA therapy, can often participate in school and social activities at the same level as their peers.
How can ABA therapy help my child?
Every child’s journey is unique, and ABA therapy is personalized to meet your family’s priorities. At ABC, we focus on helping children build practical, everyday skills while supporting families along the way.
ABA therapy can help your child grow in:
- Communication: Using words, gestures, or devices to express needs and connect with others
- School readiness: Learning to imitate, follow routines, and build pre-academic skills
- Behavior support: Finding safe, effective ways to meet needs while reducing unsafe behaviors like aggression, self-injury, or elopement
- Social skills: Playing with peers, sharing, and taking turns
- Self-care: Practicing routines like brushing teeth, washing hands, and cleaning up toys
ABC’s research shows strong outcomes: 86% of families report major reductions in challenging behaviors within the first year of therapy, along with continued progress as goals evolve.
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.
