Positive perceptions of school climate correlate with many dimensions of academic well-being and student health. Unfortunately, some existing research finds more favorable perceptions in middle school for general education students (GENs) than for students with disabilities (SWDs). Given the importance of ninth grade to student success, it is…

Background: While chronic absenteeism hurts all students, one particularly vulnerable group, students with disabilities (SWDs), has received little attention in research or policy. Particularly troubling is the dearth of research into the patterns of absences for SWDs and GENs who attend school together in urban school systems, given relatively…

Policy makers and analysts often view the reduction of student mobility across schools as a way to improve academic performance. Prior work indicates that children do worse in the year of a school move, but has been largely unsuccessful in isolating the causal effects of mobility. We use longitudinal data on students in New York City public…

Research finds that small high schools deliver better outcomes than large high schools for urban students. An important outstanding question is whether this better performance is gained at the expense of losses elsewhere: Does small school reform lift the whole district? We explore New York City's small high school reform in which hundreds of new…

The majority of existing research on mobility indicates that students do worse in the year of a school move. This research, however, has been unsuccessful in isolating the causal effects of mobility and often fails to distinguish the heterogeneous impacts of moves, conflating structural moves (mandated by a school's terminal grade) and…

A series of policy shifts over the past decade promises to change how Americans decide where to send their children to school. In theory, the expanded use of standardized test scores and the boom in charter schools will allow parents to evaluate their assigned neighborhood school, or move in search of a better option. But what kind of data do…
