Our Mission Statement

It is our mission to provide our clients with the skills to enjoy an independent and fulfilling life imbued with meaningful relationships. We ensure that our interventions are as effective and relevant as possible by collaborating with the clients’ stakeholders, drawing from the latest research and applying the scientist-practitioner model. Additionally, the end-point of all interventions is a demonstration of the desired outcome with the relevant caregivers in the natural environment.

About Us

children with disabilities smilingABC, a developmental disability care in Tennessee, endeavors to help children and young adults alike overcome their daily challenges due to their health condition. We aim to provide individualized Applied Behavior Analysis (ABA) therapy for children and young adults with autism across the spectrum by using the latest research to inform therapy procedures and providing high-quality, ongoing training to our behavior therapists.

High-Quality Supervision

Intensive initial and ongoing training is provided for our RBTs to refine and maintain their skills. Additionally, RBTs earn a bonus hourly pay rate calculated monthly based on the quality of their performance. Supervising BCBAs provide the RBTs with weekly feedback using an observation checklist to help them prepare for a monthly video submission of their performance which is reviewed by the leadership team. This high-expectation, high-pressure environment is attractive only to those RBTs with a strong drive to learn to be the best therapist possible. RBTs receive additional support during our weekly clinical review meetings where they can ask more in-depth questions of BCBAs in a distraction-free environment and where they can role-play scenarios to sharpen their skills.

Our Values

1. Collaboration is vital to our success! Your BA (Behavior Analyst) will work closely with parents, teachers and other caregivers to determine and prioritize behavior goals and effectiveness of your child’s behavior therapy. This will ensure that the Behavior Support Plan (BSP) takes into consideration:

  • Unique differences of your child
  • Parent values
  • Family culture
  • Practical constraints

2. Positive Reinforcement:
ABA (Applied Behavior Analysis) Therapy sessions are designed to be fun, whether they are focused on skill acquisition (social language, or academic) or reducing problem behaviors. Play time with your BA and other positive reinforcers are used to keep your child motivated to work hard. For reducing problem behaviors, socially appropriate alternative behaviors will be taught that will allow your child to get their needs met or cope with difficult situations.

3. Whenever possible, natural reinforcement will be used to motivate behavior changes. When arbitrary reinforcement (e.g. candy) is used, a plan to systematically transition to natural reinforcement will be developed by your BA.

4. Evidence-Based. Advances in ABA Therapy are continually generated by ongoing research in autism and behavior. Your BA studies and evaluates newly published research to ensure that, if a new development would be therapeutically relevant to your child and his/her situation, it will be incorporated into your child’s BSP and therapy curriculum.

What is ABA?

Behavior Analysis is the scientific study of behavior. Applied Behavior Analysis (ABA) is the application of the principles of learning and motivation from Behavior Analysis and the procedures and technology derived from those principles, to the solution of problems of social significance. Many decades of research have validated treatments based on ABA.

The Report of the MADSEC Autism Task Force (2000) provides a succinct description, put together by an independent body of experts:

Over the past 40 years, several thousand published research studies have documented the effectiveness of ABA across a wide range of:

  • populations (children and adults with mental illness, developmental disabilities and learning disorders including, but not limited to Autism Spectrum Disorders)
  • interventionists (parents, teachers and staff)
  • settings (schools, homes, institutions, group homes, hospitals and business offices) and
  • behaviors (language; social, academic, leisure and functional life skills; aggression, selfinjury, oppositional and stereotyped behaviors)

Applied behavior analysis is the process of systematically applying interventions based upon the principles of learning theory to improve socially significant behaviors to a meaningful degree and to demonstrate that the interventions employed are responsible for the improvement in behavior (Baer, Wolf & Risley, 1968; Sulzer-Azaroff & Mayer, 1991).
