Except where there is a consultative agreement, the licensed behavior analyst is ultimately responsible for the design and implementation of behavior analytic services that are in the best interest of the client, under the licensed behavior analyst’s supervision. Behavior analysis involves the design, implementation, and evaluation of systematic instructional and environmental modifications to produce socially significant improvements in human behavior. The responsibilities of a licensed behavior analyst are as follows: Objective measurement and description of specific levels of client behavior at baseline and throughout treatment; An emphasis on understanding the current function or functions and future importance of behaviors targeted for treatment; Efforts to design, establish, and manage treatment environments in order to minimize problem behaviors and maximize progress on treatment targets; Use of a carefully constructed, individualized, and detailed behavior analytic treatment plan that: Utilizes reinforcement and other scientifically validated behavior analytic procedures as opposed to procedures that lack scientific evidence of effectiveness; Is designed to establish small units of behavior and build toward larger, clinically important changes in behavior that result in improved client health and functioning; Includes ongoing, frequent, direct observation and objective measurement of treatment targets and analysis of the resulting data in order to adjust treatment procedures to maximize client progress; and Is implemented repeatedly, frequently, and consistently across multiple environments by the licensed behavior analysts’ supervisees, and the client’s caregivers who are trained and supervised by the licensed behavior analyst to implement specified components of the treatment plan; and Determination and supervision of tasks to be performed by a supervisee based on the supervisee’s training, experience, and competence, in accordance with the responsibilities for supervision described in Regulation .13 of this chapter.
