A number of textbooks and professional volumes in applied behavior analysis suggest that interventions designed primarily to decrease a problem behavior should routinely be accompanied by efforts to increase the frequency of at least one appropriate behavior. Some sources describe the objective of this tactic as “replacing” the problem behavior. This paper considers rationales that might underlie this advice, as well as reasons why a general rule to this effect is inappropriate. This review reveals that although there may well be good reasons for considering this tactic, their rationales are often not well articulated and may even be unsound. It is also the case that there are good reasons why this tactic may not always be necessary, thus conflicting with an argument for a general rule.

This article reviews the origins and characteristics of the positive behavior support (PBS) movement and examines those features in the context of the field of applied behavior analysis (ABA). We raise a number of concerns about PBS as an approach to delivery of behavioral services and its impact on how ABA is viewed by those in human services. We also consider the features of PBS that have facilitated its broad dissemination and how ABA might benefit from emulating certain practices of the PBS movement.

This paper describes a national certification program for behavior analysts and summarizes the background, content, policies, future development, and benefits of this program. The program focuses on applied behavior analysis in general and certifies behavior analysts at both baccalaureate and master's levels. Eligibility requirements to take either of the two examinations include both coursework and mentored or supervised experience. The paper details a number of benefits that may be expected from this professional credential, which are based on experiences in Florida, the source of the present examination.
