“…A large body of literature exists devoted to researching the impact of school leaders' management styles and educational processes (see Bossi, 2008;Hatrick, 2008;Kelley, Thornton, & Daugherty, 2005;Knuth & Banks, 2006;Leithwood, Seashore Louis, Anderson, & Wahlstrom, 2005;Loesch, 2010;Marzano, Waters, & McNulty, 2005).

The literature on school leadership has been conducted from a diverse spectrum of methodological perspectives, including case studies, meta-analyses, longitudinal studies, and narrative methods.…”
