Applied behavior analysis (ABA) is the use of the principles and procedures of behavior analysis to better understand and improve lives. Treatment approaches based on ABA have been empirically shown to be effective in a wide variety of areas. However, because ABA was first applied to the treatment of individuals with intellectual disabilities and autism, this practice area has the largest evidence base and has received the most recognition. The following educational resources highlight some of the many ABA subspecialty areas. Additional resources will be added to this webpage in the future. The resources below were produced in partnership with dozens of subject matter experts who provided all of the intellectual content. These resources may be freely distributed and hosted online.

Note: for the purposes of BACB certifications and examinations, ABA is defined as the content of the BCBA/BCaBA Task List and RBT Task List.
