“…Principal leadership is foundational to school culture development and implementation of organizational structures and practices, which, in turn, affect a variety of student outcomes (Grissom & Loeb, 2011; Leithwood, Louis, Anderson, & Wahlstrom, 2004; Williams, Kirst and Haertal, 2010). Advocates for middle grades students outline specific leadership practices that support organizational cultures and structures addressing the unique developmental needs of young adolescents (Brown & Anfara, 2002; Jackson & Davis, 2000; Keefe, Valentine, Clark, & Irvine, 1994), suggesting such developmentally appropriate practices positively affect student outcomes (Arhar & Kromrey, 1995; Felner, Jackson, & Kasak, 1997; Mertens & Flowers, 2003; National Middle School Association, 2010a). Although the research specifically examining principal leadership at the middle level is limited (Gale & Bishop, 2014; Juvonen, Le, Kaganoff, Augustine, & Constant, 2004), the extant research of U.S. middle grades leadership suggests highly successful middle grades schools are more likely to be led by principals who engage in practices that align with the developmental needs of young adolescents (Brown & Anfara, 2002; Clark & Clark, 2000; Gale & Bishop, 2014; Sanzo, Sherman, & Clayton, 2011; Valentine, Clark, Hackman, & Petzko, 2004).…”
