Classroom teachers in the United States are absent on average approximately 6 percent of a school year. Despite the prevalence of teacher absences, surprisingly little research has assessed the key source of replacement instruction: substitute teachers. Using detailed administrative and survey data from a large urban school district, we document…

Purpose: Recent attempts to measure schools' influence on students' social-emotional learning (SEL) show differences across schools, but whether these estimated differences measure the true effects of schools remain unclear. To better understand these measures, we examine the stability of estimated school-by-grade effects across 2 years using…

Hiring presents an important opportunity for districts to find educators with values and beliefs that align with district goals. Yet beliefs about how to best address persistent challenges like inequality are difficult to measure. We use administrative data from over 10,000 applications to certificated positions in an urban California school…

Educators raise concerns about what happens to students when they are exposed to new or new-to-school teachers. However, even when teachers remain in the same school they can switch roles by moving grades and/or subjects. We use panel data from New York City to compare four ways in which teachers are new to assignment: new to teaching, new to…

School Improvement Grants (SIG) represent one type of governments' capacity-building investment to spur sustainable changes in America's persistently under-performing public schools. This study examines both short- and long-run effects of the first two cohorts of SIG schools from two states and two urban districts across the country. Using dynamic…

Despite growing concern over teachers' ability to live comfortably where they work, we know little about the systematic relationship between affordability and teachers' well-being, particularly in high-cost urban areas. We use novel survey data from San Francisco Unified School District to identify the patterns and prevalence of economic anxiety…

Teacher effectiveness varies substantially, yet principals' evaluations of teachers often fail to differentiate performance among teachers. We offer new evidence on principals' subjective evaluations of their teachers' effectiveness using two sources of data from a large, urban district: principals' high-stakes personnel evaluations of teachers,…

Tenure is intended to protect teachers with demonstrated teaching skills against arbitrary or capricious dismissal. Critics of typical tenure processes argue that tenure assessments are superficial and rarely discern whether teachers in fact have the requisite teaching skills. A recent reform of the tenure process in New York City provides an…

School value-added models are increasingly used to measure schools' contributions to student success. At the same time, policymakers and researchers agree that schools should support students' socialemotional learning (SEL) as well as academic development. Yet, the evidence regarding whether schools can influence SEL and whether statistical growth…

Despite the multifaceted causes of educational disparities, schools' responsibility for reducing inequality undergirds American ideals. Educators operate as street-level bureaucrats to accomplish this equalizing work. Surprisingly, we know little about how teachers think about inequality or enact strategies to combat it, even though their…

This paper describes teacher tenure reforms first enacted by the New York City Department of Education (NYCDOE) during the 2009-10 academic year (AY) and the changes in the district's teacher workforce following the reforms. We show that the reforms dramatically changed the proportion of eligible teachers receiving tenure, as well as the career…

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…

Mounting evidence demonstrates that social-emotional skills are important for students' academic and life success, yet we have limited evidence on how these skills develop over time and how this development varies across student subgroups. In this study, we use the first large-scale panel survey of social-emotional learning (SEL) to describe how…

Politics of education researchers have long recognized the role of micropolitics in school decision-making processes. We argue that investigating micropolitical dynamics is key to an important set of school decisions that are fundamental to inequities in access to high-quality teachers: assignments of teachers and students to classrooms. Focusing…
