A school's success is largely determined by the effectiveness of its principal--decades of research have made this clear. Less settled is the question of what principals need to know and do to drive positive outcomes in their schools. A recent report funded by The Wallace Foundation provides evidence on the connection between school principals and…

Research demonstrates the importance of principal effectiveness for school performance and the potentially negative effects of principal turnover. However, we have limited understanding of the factors that lead principals to leave their schools or about the relative effectiveness of those who stay and those who turn over. We investigate the…

Studies link principal effectiveness to lower average rates of teacher turnover. However, principals need not target retention efforts equally to all teachers. Instead, strong principals may seek to strategically influence the composition of their school's teaching force by retaining high performers and not retaining lower performers. We…

Numerous studies investigate high-stakes personnel evaluation systems in education, but nearly all focus on evaluation of teachers. We instead examine the evaluation of school principals at scale using data from the first 4 years of implementation of Tennessee's multiple-measure administrator evaluation system. We focus specifically on the…

The quality of a school's leadership is a key determinant of its performance. Research links effective leadership to a variety of school outcomes, including more positive school learning climates (Sebastian & Allensworth, 2012), lower rates of teacher turnover (Boyd et al., 2011; Grissom & Bartanen, 2018; Ladd, 2011), and greater parental…

Purpose: Concerns about variation in the quality of preservice preparation provided by many university-based principal preparation programs (PPPs) has led to calls to use outcomes of program graduates to hold PPPs accountable. Little research, however, has assessed the degree to which different outcomes for PPP graduates in fact vary…

Nationally, 18% of principals turn over each year, yet research has not yet credibly established the effects of this turnover on student and teacher outcomes. Using statewide data from Missouri and Tennessee, we employ a difference-in-differences model with a matched comparison group to estimate arguably causal effects. We find that principal…

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…

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

Numerous studies document the inequitable distribution of teacher quality across schools. We focus instead on the distribution of principal quality, examining how multiple proxies for quality, including experience, teachers' survey assessments of leaders, and rubric-based practice ratings assigned by principals' supervisors, vary by measures of…

Research over the past 35 years consistently reveals that principals spend minimal amounts of time on instructional leadership activities. Similarly, we know very little about how principals might be trained to change their time allocation to focus more on instructional leadership tasks. The paper describes the implementation and the time use of…

Purpose: Concerns about variation in the quality of pre-service preparation provided by many university-based principal preparation programs (PPPs) has led to calls to use outcomes of program graduates to hold PPPs accountable, which the recent growth of state administrative data systems has made feasible. Little research, however, has assessed…

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…

Expansion of the use of student test score data to measure teacher performance has fueled recent policy interest in using those data to measure the effects of school administrators as well. However, little research has considered the capacity of student performance data to uncover principal effects. Filling this gap, this article identifies…

Purpose: Time demands faced by school principals make principals' work increasingly difficult. Research outside education suggests that effective time management skills may help principals meet job demands, reduce job stress, and improve their performance. The purpose of this paper is to investigate these hypotheses. Design/methodology/approach:…
