Applied Behavior Analysis (ABA) is a science in which procedures are systematically applied to improve socially significant behavior to a meaningful degree. An ABA program is a systematic teaching approach that involves breaking skills down into small, easy-to-learn steps. Praise or other rewards are used to motivate the child, and progress is continuously measured so the teaching program can be adjusted as needed. ABA is widely recognized as the single most effective treatment for children with autism spectrum disorder and the only treatment shown to lead to substantial, lasting improvements in the lives of individuals with autism. ABA-based treatment strategies maximize the learning potential of persons with ASD, and are flexible, individualized and dynamic.
