Schoolwide Positive Behavior Support in an Alternative School Setting: An Evaluation of Fidelity, Outcomes, and Social Validity of Tier 1 Implementation

The paucity of research investigating the effectiveness of universal behavioral strategies for supporting students in alternative educational settings is of great concern. However, a growing literature base supporting schoolwide positive behavioral support interventions (SWPBS) has been encouraging. This program evaluation provides additional support for this literature, indicating a positive impact of SWPBS Tier 1 implementation on key student outcome measures in a school serving students in Grades 5–12 identified with emotional disturbance or as otherwise health impaired. In addition, this program evaluation includes measures and positive findings for both (a) implementation fidelity and (b) social validity in this alternative school setting.
