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).

Residential mobility is likely to have consequences for student performance, but prior empirical work is largely correlational and offers little insight into its impacts. Using rich, longitudinal data, we estimate the effects of residential mobility on the performance of New York City public school students. Using both student fixed effects and…

Recent research finds that grade span affects academic achievement but only speculates about the mechanisms. In this study, we examine one commonly cited mechanism, the top dog/bottom dog phenomenon, which states that students at the top of a grade span ("top dogs") have better experiences than those at the bottom ("bottom…

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…
