The field of educational leadership has accrued a body of research that explains how leaders influence student achievement through the enactment of various practices. Yet, differences exist in the substance of the frameworks that assert the areas to which leaders should attend. The specific purposes of this article are to identify and synthesize the empirical research on how leadership influences student achievement and to provide evidence on how school leaders should direct their efforts. During the literature review, we consulted experts for recommendations and searched peer-reviewed journals from 2000 to 2014. The literature review yielded 56 empirical research studies of relevance to the topic and 3 frameworks consisting of clustered practices. We then grouped the 28 practices according to systematic criteria and found 5 overarching domains. In doing so, this study unifies existing frameworks through developing a cohesive set of practices to inform the work of researchers and practitioners.
