Note. Entries show means and standard deviations are shown in parentheses. The IRT scores were scaled such that a score of “0” approximates the achievement level of a student in first grade. The p-value column lists p-values from regressions in which each variable listed was regressed on treatment status. P-values less than 0.001 were rounded to 0.001.
