“…While the primary features of PBIS implementation are the same regardless of instructional level and setting, implementation in high schools is complicated by contextual factors such as the focus on graduation requirements, supporting the transition from high school to post-school education and employment, and the unique social and emotional needs of PBIS IN HIGH SCHOOLS adolescents (Flannery, Frank, Kato, Doren, & Fenning, 2013). Further, few studies have focused on the effects of PBIS implementation at all 3 tiers in schools at any instructional level (Stewart, Benner, Martella, & Marchand-Martella, 2007). Understanding that the primary student variables that are associated with high school completion include attendance, behavior, and academic performance (Balfanz, Herzog, & Mac Iver, 2007;Hammond, Linton, Smink, & Drew, 2007), there is a need for in-depth research about how PBIS implementation and evidence-based social/emotional skills development can be implemented in high schools and improve student outcomes as they move into adulthood.…”
