Applied Behavior Analysis


Applied Behavior Analysis (ABA) is the evidence-based practice and set of interventions often associated with autism spectrum disorders and other developmental disabilities. 


ABA includes directly observing the behavior, measurement and data collection procedures, and functional analyses of the relations between the environment and behavior in order to produce socially significant behavior changes. 


ABA uses ABC data collection procedures: observing the Antecedent stimuli (what occurred in the environment immediately preceding the behavior), operationally defining (detailed description) the Behavior, and recording the Consequences (what occurred immediately following the behavior). These findings, along with descriptive and functional analyses are used to produce behavior changes. ABA focuses on defining behavior in terms of external factors that can be manipulated rather than internal factors that are beyond our control.



At ABC's of Applied Behavior Analysis, our mission is to provide evidence-based behavior services to learners with autism spectrum and related disorders. We use the principles and procedures of Applied Behavior Analysis (ABA) to provide comprehensive services to children and their families.  ABC’s of ABA develops programs specific to each child’s needs and provides necessary training and supervision to help replicate and generalize these interventions throughout different environments, including home, school, and clinic. Research shows ABA therapy is the most effective evidence-based treatment for Autism and we recognize the capability & uniqueness within every child and want to help each child maximize their potential. We specialize in early intervention and work with children ages 2 to 21. ABC's of ABA is natural environment based, using each child’s individual strengths and motivations to foster their potential.
