The purpose of this study was to examine a positive behavior support plan implemented in a correctional facility for male juveniles to determine its effectiveness in changing behavior. The study was precipitated by teachers' concern with the punishment orientation of the facility and the need to do Functional Behavior Assessment for students' Individualized Education Programs as mandated by IDEA, 1997. The study took place over a four-month period. Participants in the study were 14 to 18 years of age. The program as an entity was examined as opposed to tracking individual boy's behavior, due to the continual admittance and dismissal of students. Positive behavior supports immediately increased appropriate behavior and sustained it throughout the duration of the study. Every student met with behavior success the majority of their school day. They benefited from the opportunity to substitute inappropriate behavior for appropriate behavior. Consecutive days of problem behavior by an individual student were limited. This appears to be due to the program design that provided the incentive of a fresh start every day. (Contains 5 tables.)
