The report is an update to the 2004 literature review, "How Leadership Influences Student Learning," which helped establish the importance of principals after concluding that school leadership was second only to classroom instruction in school-related impacts on student learning. The updated synthesis draws on 219 research studies about…

Teacher evaluation systems that pair measures of teacher observation with measures of student achievement or growth have become widespread. However, little attention has focused on the impact of teacher evaluation systems--and, in particular, the intensive collection and use of data from teacher observations--on principals. Drawing on interviews…

In 2014, The Wallace Foundation launched the Principal Supervisor Initiative (PSI), a four-year, $24 million-dollar effort to redefine principal supervision in six urban school districts. The initiative sought to help districts transform a position traditionally focused on administration, operations, and compliance to one dedicated to developing…

School performance pressures apply disproportionately to tested grades and subjects. Using longitudinal administrative data--including achievement data from untested grades--and teacher survey data from a large urban district, we examine schools' responses to those pressures in assigning teachers to high-stakes and low-stakes classrooms. We find…

Principals play a central role in how well a school performs. They are responsible for establishing school goals and developing strategies for meeting them. They lead their schools' instructional programs, recruit and retain teachers, maintain the school climate, and allocate resources. How well they execute these and other leadership functions is…

This three-volume report describes the "SAM (School Administration Manager) process," an approach that about 700 schools around the nation are using to direct more of principals' time and effort to improve teaching and learning in classrooms. Research has shown that a principal's instructional leadership is second only to teaching among…

Scholars have long argued that principals should be "instructional leaders," but few studies have empirically linked specific instructional leadership behaviors to school performance. This study examines the associations between leadership behaviors and student achievement gains using a unique data source: in-person, full-day…

Background: High rates of teacher turnover likely mean greater school instability, disruption of curricular cohesiveness, and a continual need to hire inexperienced teachers, who typically are less effective, as replacements for teachers who leave. Unfortunately, research consistently finds that teachers who work in schools with large numbers of…

While the importance of effective principals is undisputed, few studies have addressed what specific skills principals need to promote school success. This study draws on unique data combining survey responses from principals, assistant principals, teachers and parents with rich administrative data to identify which principal skills matter most…
