This systematic review sought to expand our knowledge of the increasing research studies focusing on the empirical link between school leadership and student achievement. Using five different data sources (Scopus, WoS, ERIC, Google Scholar, and Retrospective Reference Harvesting Procedure), we created a data set of 144 journal articles. Descriptive analysis of bibliographic data and content analysis of full texts were employed in the review process. The results revealed instructional leadership as the most frequently used school leadership model in the relevant research. There has been a growing tendency to use the direct effect model with the increase in the studies from non-English speaking western societies. Indeed, the use of rational and organizational variables has dominated the mediating effect studies, while moderating effect studies as well as exploratory and explanatory type of studies have not received much attention. Based on these results, a framework representing the broader picture of the current research on the relationship between school leadership and student learning is provided. In addition, several recommendations were made, aiming to build the research capacity in furthering our understanding of how school leadership practices impact student learning and achievement.
