Studies of school effectiveness (Edmonds, 1979;Hawley & Rosenholtz, 1984;Hill & Rowe, 1996;Mortimore, 1993;Rutter, 1983;Sammons, Nuttall, Cuttance, & Thomas, 1995), school improvement (Foster, 2005;Jackson, 2000;Nicolaidou & Ainscow, 2005), effective classrooms (Creemers, 1994), and school leadership (Hallinger et al, 1996;Heck et al, 1990;Marks & Printy, 2003;Wiley, 2001) have contributed towards a more integrated understanding of how schools make a difference in learning (Ouston, 1999;Reynolds et al, 2000). This study incorporated key variables actively targeted in current school improvement efforts in its model of leadership and student learning.…”
