What is Applied Behavior Analysis (ABA)?

Applied Behavior Analysis (ABA) is a therapy based on the science of learning and behavior.

ABA therapy applies our understanding of how behavior works to real situations. The goal is to increase behaviors that are helpful and decrease behaviors that are harmful or affect learning.

ABA therapy programs can help:

  • Increase language and communication skills

  • Improve attention, focus, social skills, memory, and academics 

  • Decrease problem behaviors


The methods of behavior analysis have been used and studied for decades. Applied Behavior Analysis involves many techniques for understanding and changing behavior. ABA is a flexible treatment and is adapted to meet the needs of each unique person.

The goal of any ABA program is to help each person work on skills that will help them become more independent and successful in the short term as well as in the future.

In ABA, a qualified and trained behavior analyst (BCBA) designs and directly oversees the program. They customize the ABA program to each learner's skills, needs, interests, preferences and family situation.

Treatment goals are written based on the age and ability level of the person with ASD. Goals can include many different skill areas, such as:

  • Communication and language

  • Social skills

  • Self-care (such as showering and toileting)

  • Play and leisure

  • Motor skills

  • Learning and academic skills

ABA therapy programs involve technicians, or registered line technicians (RBTs). These technicians are trained and supervised by the BCBA. They work directly with children and adults with autism to practice skills and work toward the individual goals written by the BCBA.

The BCBA and technicians measure progress by collecting data in each therapy session. Data helps them to monitor the person’s progress toward goals on an ongoing basis.

The behavior analyst regularly meets with family members and program staff to review information about progress. They can then plan ahead and adjust teaching plans and goals as needed.

ABA is considered an evidence-based best practice treatment by the US Surgeon General and by the American Psychological Association. “Evidence based” means that ABA has passed scientific tests of its usefulness, quality, and effectiveness.


More than 20 studies have established that intensive and long-term therapy using ABA principles improves outcomes for many but not all children with autism.

Brennan Behavior Group is proud to offer ABA services in both clinic-based and school-based capacities and our services are offered to individuals of all ages!

School-Based ABA Therapy

We work with many private, public, and parochial school districts across the New Orleans metropolitan area to provide Applied Behavior Analysis (ABA) treatment, behavior support services and educational consultation services for children with autism and other developmental disorders.


Our approach towards a school based ABA treatment program is all about positive reinforcement and empowerment of children. We believe that the school staff and our BCBA experts must work closely together to help children reach their fullest potential.


Our comprehensive school-based ABA services are delivered by trained ABA therapists and supervised by Board Certified Behavior Analysts (BCBAs).

Clinic-Based ABA Therapy

Brennan Behavior Group is proud to offer clinic-based ABA services.  Our clinic-based ABA services are available for Focused and Comprehensive ABA Treatment.

Focused ABA Treatment: Focused ABA ranges from 10-25 hours per week of direct treatment (plus direct and indirect supervision and caregiver training). However, certain programs for severe destructive behavior may require more than 25 hours per week of direct therapy (for example, learners that have no functional communication system or have high rates of severe problem behavior).

Comprehensive ABA Treatment: Comprehensive ABA Treatment often involves an intensity level of 30-40 hours of 1:1 direct treatment to the client per week, not including caregiver training, supervision, and other needed services. However, very young children may start with a few hours of therapy per day with the goal of increasing the intensity of therapy as their ability to tolerate and participate permits. Treatment hours are subsequently increased or decreased based on the client’s response to treatment and current needs. Hours may be increased to more efficiently reach treatment goals. Decreases in hours of therapy per week typically occur when a client has met a majority of the treatment goals and is moving toward discharge.


Although the recommended number of hours of therapy may seem high, this is based on research findings regarding the intensity required to produce good outcomes. It should also be noted that time spent away from therapy may result in the individual falling further behind typical developmental trajectories. Such delays will likely result in increased costs and greater dependence on more intensive services across their life span.
