The Scope of Practice of Applied Behavior Analysis in State Licensure Laws

The scope of applied behavior analysis has historically been defined by behavior analytic publications like Baer et al., Journal of Applied Behavior Analysis, 1, 91, (1968). However, starting in 2009, state legislators began creating licensure laws for behavior analysts that formalized the scope of practice for applied behavior analysis (ABA) within the applicable states. The purpose of this study was twofold: (1) to evaluate the degree scope of practice statements found in state licensure laws aligned with the individual components of Baer et al.'s seven dimensions of ABA and the APBA Model Act and (2) to evaluate the consistency of the scope of practice statements across states. Each licensed state law was identified, and the section that outlined the scope of practice was isolated and coded. The results of this study identified varying degrees of alignment with the individual components of Baer et al.'s seven dimensions and the APBA Model Act, as well as inconsistencies in the scope of practice among states with licensure for ABA. The component scores of each content area will be discussed, along with the implications for practice.
