Over the past two decades, theorists and researchers have consistently cited the importance ofeffective school leadership in relation to improved educational outcomes (Fullan, 2002; Hallinger &Heck, 1998; Leithwood, Jantzi, & Steinbach, 1999; Leithwood, Louis, Anderson, & Wahlstrom, 2004).The Wallace Foundation recently commissioned an exhaustive research project on the relationshipsbetween school leadership and student learning, and the authors concluded that "when principals andteachers share leadership, teachers’ working relationships with one another are stronger and studentachievement is higher" (Louis, Leithwood, Wahlstrom, & Anderson, 2010, p. 282).
