Balanced Leadership: What 30 Years of Research Tells Us About the Effect of Leadership on Student Achievement

BACKGROUND
More than three decades of researchi on the effects of instruction and schooling on student achievement are creating a new science of education. Starting in 1998, McREL began synthesizing this growing body of research through meta-analyses of research on student characteristics and teacher and school practices associated with school effectiveness. The results of our first two meta-analyses have provided practitioners with specific guidance on the curricular, instructional, and school practices that, when applied appropriately, can result in increased student achievement.
