Charter schools are funded and governed by public agencies but operated by private organizations under government contracts. As private organizations, charter schools have more autonomy over their operations than traditional public schools. Charter school teachers typically do not work under collective bargaining units or have tenure protections,…

We study the combined effects of charter schools, and their various mechanisms, on a national level and across multiple outcomes. Using difference-in-differences and fixed effects methods, we find that charter entry (above 10 percent market share) increases high school graduation rate in geographic districts by about 2-4 percentage points and…

We describe the levels, trends, and patterns of school closure and restructuring in the United States from 1991 to 2019 across all sectors using a near census of K-12 schools. Focusing on the years with the best available data, 2014-2018, we find that the annual closure rate of charter, private, and traditional public schools (TPS) were 5.1, 2.9,…

We provide the first broad-scale evidence regarding the effect of school reopenings on COVID-19 health outcomes. We specifically focus on COVID-19-related hospitalizations, which directly measure the health outcomes of greatest interest and are not subject to the numerous measurement problems that arise with virus positivity rates and contact…

High school graduation rates have increased dramatically in the past two decades. Some skepticism has arisen, however, because of the confluence of the graduation rise and the starts of high-stakes accountability for graduation rates with "No Child Left Behind" (NCLB). In this study we provide some of the first evidence about the role of…

Schools often struggle to attract and retain high-performing teachers and to develop or remove low-performing ones. In this study, the researchers considered whether this is true in New Orleans where almost all schools are charters with flexibility over personnel policies and practices, and where schools compete against one another and face…

We investigate student mobility in a choice-based system that has gone to scale, New Orleans, to gain insight into an underlying improvement mechanism of choice-based reform and its potential equity-related consequences. In contrast to typical analyses of mobility, this study distinguishes incumbent school characteristics that can cause students…

New Orleans schools experienced drastic reforms after Hurricane Katrina in 2005. To examine teachers' perspectives on these reforms, we surveyed 323 teachers who taught in New Orleans public schools before 2005 and in 2013-2014. Teachers directly compared the learning and work environments and student and teacher outcomes of their current schools…

COVID-19 has forced essentially all schools in the country to close their doors to in-person activities. In this study, we provide new evidence about variation in school responses across school types. We focus on five main constructs of school activity during COVID-19: personalization and engagement in instruction, personalization and engagement…

COVID-19 has become one of the greatest crises ever facing the country. It is also, therefore, one of the greatest crises facing the nation's schools. This brief describes how America's schools have adjusted to operating while their buildings have been shuttered. In particular, how did different types of schools respond in different ways? This…

The authorizers of charter schools are an understudied piece of the charter reform process. The local school boards, state agencies, and higher education institutions that act as authorizers play a significant role in the market, determining which operators get to enter the market and which are forced to exit. This article provides an…

In the recent drive to revamp teacher evaluation and accountability, measures of a teacher's value added have played the starring role. But the star of the show is not always the best actor, nor can the star succeed without a strong supporting cast. In assessing teacher performance, observations of classroom practice, portfolios of teachers' work,…

In most of the U.S., the process for assigning children to public schools is straightforward: take a student's home address, determine which school serves that address, and assign the student accordingly. However, states and cities are increasingly providing families with school choices. A key question facing policymakers is exactly how to place…

In "Value-Added Measures in Education", Douglas N. Harris takes on one of the most hotly debated topics in education. Drawing on his extensive work with schools and districts, he sets out to help educators and policymakers understand this innovative approach to assessment and the issues associated with its use. Written in straightforward language…

In this policy brief, the author explores the problems with attainment measures when it comes to evaluating performance at the school level, and explores the best uses of value-added measures. These value-added measures, the author writes, are useful for sorting out-of-school influences from school influences or from teacher performance, giving…
