Applied Behavior Analysis (ABA) is a scientific approach and the leading researched-based methodology proven to bring about positive, meaningful changes in behavior, particularly in individuals with challenging needs such as autism and learning disabilities. Endorsed by state and federal agencies, including the U.S. Surgeon General, ABA is utilized to address developmental areas of need such as communication, academic, and social skills, facilitating successful and productive lives. Over the past two decades, there has been a significant increase in the utilization of ABA not only for autism but also for various developmental, learning, and behavioral difficulties across all age groups.
