Note: Data are drawn from WCPSS administrative records. Reading achievement data are available for students in grades 3–8. All models include controls for student race/ethnicity, gender, special education, and ELL status; percent of students reassigned into student’s assigned school, percent of students reassigned out of student’s assigned school, node-by-grade fixed effects, year fixed effects as described in Equation (1). While all models include terms for 4 or more years before and after reassignment, these are not reported here due to imprecision. One year before reassignment represents the reference year and is indicated by “—”.
