Faced with decreasing funds and increasing costs, a growing number of school districts across the United States are switching to four-day school weeks (4DSWs). Although previously used only by rural districts, the policy has begun to gain traction in metropolitan districts. We examine homeowner, teacher, and student outcomes in one of the first metropolitan school districts to adopt the 4DSW. We find 2 to 4 percent home price declines relative to surrounding school districts, a 5 percent decrease in teacher retention for experienced teachers, and a 0.2 to 0.3 standard deviation decrease in student test scores. These results suggest the decision to adopt a 4DSW in a metropolitan setting should not be taken lightly.
We study the returns to experience in teaching, estimated using supervisor ratings from classroom observations. We describe the assumptions required to interpret changes in observation ratings over time as the causal effect of experience on performance. We compare two difference-in-differences strategies: the two-way fixed effects estimator common in the literature, and an alternative which avoids potential bias arising from effect heterogeneity. Using data from Tennessee and Washington, DC, we show empirical tests relevant to assessing the identifying assumptions and substantive threats—e.g., leniency bias, manipulation, changes in incentives or job assignments—and find our estimates are robust to several threats.
Growing up in poverty presents numerous nonacademic barriers that impede academic progress for economically disadvantaged students (Duncan and Murnane, 2016). Because schools alone have limited capacity to address the systemic nature of economic inequalities that directly affects student outcomes, policymakers and researchers in recent years have increased calls for the use of comprehensive, integrated support models and wraparound services (Wasser Gish, 2019). Although research on the effects of such interventions has been mixed, evaluations of one model – City Connects – have found significant achievement gains for students who received the intervention in elementary school (Walsh et al., 2014). Given the need to understand the replicability of interventions beyond initial sites of implementation, we assessed the degree to which the intervention effect on math and English Language Arts (ELA) achievement in elementary and middle school replicates in a new site with an important geographical variation. Results from two-way fixed effects and event-study models suggest positive treatment effects of nearly half a standard deviation in both subjects following five years of implementation, supporting the replicability of City Connects.
Across an array of educational outcomes, evidence suggests that girls outperform boys on average. For example, in Chicago, ninth-grade girls earn math GPAs that are 0.29 points higher than boys on average. This paper examines explanations for this gap, such as girl-boy differences in academic preparation, behaviors and habits, and experiences in math classes. After accounting for these factors, the gender gap in math grades persists. We, then, examine the classroom-level conditions that reduce the gender gap in grades. The gap is smaller in more advanced courses like honors classes and geometry. Further, boys perform more similarly to girls in classes with male teachers. These findings highlight classroom conditions that are more conducive to the academic success of boys.
Teachers affect a wide range of students’ educational and social outcomes, but how they contribute to students’ involvement in school discipline is less understood. We estimate the impact of teacher demographics and other observed qualifications on students’ likelihood of receiving a disciplinary referral. Using data that track all disciplinary referrals and the identity of both the referred and referring individuals from a large and diverse urban school district in California, we find students are about 0.2 to 0.5 percentage points (7% to 18%) less likely to receive a disciplinary referral from teachers of the same race or gender than from teachers of different demographic backgrounds. Students are also less likely to be referred by more experienced teachers and by teachers who hold either an English language learners or special education credential. These results are mostly driven by referrals for defiance and violence infractions, Black and Hispanic male students, and middle school students. While it is unclear whether these findings are due to variation in teachers’ effects on actual student behavior, variation in teachers’ proclivities to make disciplinary referrals, or a combination of the two, these results nonetheless suggest that teachers play a central role in the prevalence of, and inequities in, office referrals and subsequent student discipline.
The impact of school resources on student outcomes was first raised in the 1960s and has been controversial since then. This issue enters into the decision making on school finance in both legislatures and the courts. The historical research found little consistent or systematic relationship of spending and achievement, but this research frequently suffers from significant concerns about the underlying estimation strategies. More recent work has re-opened the fundamental resource-achievement relationship with more compelling analyses that offer stronger identification of resource impacts. A thorough review of existing studies, however, leads to similar conclusions as the historical work: how resources are used is key to the outcomes. At the same time, the research has not been successful at identifying mechanisms underlying successful use of resources or for ascertaining when added school investments are likely to be well-used. Direct investigations of alternative input policies (capital spending, reducing class size, or salary incentives for teachers) do not provide clear support for such specific policy initiatives.
What happens when employers screen their employees but only observe a subset of output? We specify a model with heterogeneous employees and show that their response to the screening affects output in both the probationary period and the post-probationary period. The post-probationary impact is due to their heterogeneous responses affecting which individuals are retained and hence the screening efficiency. We show that the impact of the endogenous response on both the unobserved outcome and screening efficiency depends on whether increased effort on one task increases or decreases the marginal cost of effort on the other task. If the response decreases unobserved output in the probationary period then it increases the screening efficiency, and vice versa. We then assess these predictions empirically by studying a change to teacher tenure policy in New York City, which increased the role that a single measure -- test score value-added -- played in tenure decisions. We show that in response to the policy teachers increased test score value-added and decreased output that did not enter the tenure decision. The increase in test score value-added was largest for the teachers with more ability to improve students' untargeted outcomes, increasing their likelihood of getting tenure. We estimate that the endogenous response to the policy announcement reduced the screening efficiency gap -- defined as the reduction of screening efficiency stemming from the partial observability of output -- by 28%, effectively shifting some of the cost of partial observability from the post-tenure period to the pre-tenure period.
A stable learning environment is critical to high school reforms aimed at promoting postsecondary educational success. High teacher attrition can disrupt stable learning environments by uprooting student-teacher relationships and harming school climate. Educational leaders need greater understanding of how college readiness reforms alter learning environments generally, and teacher retention in particular. We study teacher turnover in two Texas College and Career Readiness School Models (CCRSM), called Early College High Schools and inclusive Science, Technology, Engineering, and Math Academies. We find (a) CCRSM schools have lower teacher turnover compared to traditional public high schools, (b) charter versions of CCRSM schools have higher turnover, but (c) non-CCRSM charters have the highest overall teacher turnover. We discuss implications for improving high school-based college readiness reforms.
The prevalence of school-based healthcare has increased markedly over the past decade. We study a modern mode of school-based healthcare, telemedicine, that offers the potential to reach places and populations with historically low access to such care. School-based telemedicine clinics (SBTCs) provide students with access to healthcare during the regular school day through private videoconferencing with a healthcare provider. We exploit variation over time in SBTC openings across schools in three rural districts in North Carolina. We find that school-level SBTC access reduces the likelihood that a student is chronically absent by 2.5 percentage points (29 percent) and reduces the number of days absent by about 0.8 days (10 percent). Relatedly, access to an SBTC increases the likelihood of math and reading test-taking by between 1.8-2.0 percentage points (about 2 percent). Heterogeneity analyses suggest that these effects are driven by male students. Finally, we see suggestive evidence that SBTC access reduces violent or weapons-related disciplinary infractions among students but has little influence on other forms of misbehavior.
Many education policymakers and system leaders prioritize recruiting and developing effective school leaders as key mechanisms to improve school climate and student learning. Despite efforts to select and support successful school leaders, however, relatively little is understood about the prior professional experiences and skillsets that principals possess upon entry into their positions. In this descriptive paper, we use 14 years of administrative data on all educators in Oregon to trace the prior professional experiences and instructional effectiveness of those who become school leaders. We highlight that many principals in Oregon acquire educational leadership experience outside the assistant principal role and outside of the school district in which they serve as principals. We also find that when future school leaders were teachers, they improved student achievement at modestly higher rates than their peers. Insight into these topics has the potential to inform the pre-service training, recruitment and professional development of school leaders.
