Notes: The first column includes the means (and standard deviations) of the 17,520 observations in schools where the percent of FRP students is below the state threshold. The second column includes estimates from difference-in-differences specifications predicting each of the characteristics listed in the row heading. Each estimate is from a separate specification. In this column, standard errors that allow for clustering within states are shown in parentheses. The third column displays regression discontinuity design estimates of the discontinuity in each of the characteristics listed in the row heading. The regression discontinuity design estimates are calculated using local linear regression with a triangle kernel and a bandwidth of 5. In this column, standard errors are shown in parentheses. Sample sizes rounded to the nearest 10 to comply with NCES nondisclosure requirements.
