Enny Elementary School (This is an actual school with a different name to protect the identity of all stakeholders. All data is real, and any names used are pseudonyms.) is in South Florida and operates under the auspices of The Palm Beach County School District. The school serves over seven hundred students with forty-three teachers and twenty-three specially trained support staff. Academically, the student population ranks below the national and state averages in all subject areas. Behaviorally, office discipline referrals, in-school suspensions, and out-of-school suspensions have increased significantly within the last three school years, while classroom disruption and abhorrent behavior dominate daily school operations. The applied dissertation's plan of intervention describes the implementation of the School-wide Positive Behavior Interventions and Supports (SWPBIS) framework with the intent of mitigating classroom/school disruptive behavior and increasing academic engagement. The researcher explores the history of classroom management to assist the educator/administrator in understanding the significance of not just avoiding repeating the past but delving into the serious inquiry of behavior and its moral and ethical ramifications regarding discipline decisions. The foundation of SWPBIS is of critical importance in its acceptance as an intervention. The literature review examines the foundation of SWPBIS, which encompasses over one hundred years of scientific behavioral research, beginning with John B. Watson's "Behaviorism," B. F. Skinner's "Operant Conditioning," and Applied Behavioral Analysis' "Learning Theory." With the notion of Enny Elementary School's enervated implementation of the SWPBIS framework in mind, the applied dissertation defines and deconstructs the SWPBIS framework and introduces its historic development to the intelligentsia of the public-school educational vanguard. The historical development segues to procedure and practice which are based on a "Tiered System of Supports" designed to differentiate between the level of support students require and "Five Inter-Related Elements": equity, systems, data, practices, and outcomes. These elements support and guide the implementers of the framework toward positive academic and behavioral outcomes. Leader-Member Exchange Theory (LMX) is extended as the leadership construct to implement SWPBIS. LMX insists that, instead of leading and managing everyone using the same techniques, leaders establish unique relationships and leadership styles with divergent employees. The researcher offers this applied dissertation to educators and administrators as a concise and researched-based manual on how to develop an effective implementation plan to properly operationalize a School-Wide Positive Behavior Interventions and Supports Program.
