The pace of implementation of PBIS in restrictive settings for juvenile offenders is accelerating. Recommendations for future research include the following: examine effects of PBIS on preventing entry into the school-to-prison pipeline, identify factors that influence PBIS implementation, develop the capacity of restrictive settings to engage in data-based decision making, create models of professional development to facilitate implementation with fidelity, and evaluate the impact on recidivism. Ongoing efforts to reform the systems and practices within these settings must include PBIS. To accomplish these goals, leadership must adopt a long-term vision for PBIS efforts and researchers should contribute to this vision by informing implementation practice and linking practices to outcomes through effective decision-making.
