Notes: The adjusted difference between control and treatment is the result of a regression of the dependent variable against fixed effects for randomization strata, a treatment indicator, and an indicator for whether the school is an elementary or middle school. Standard errors (SE) are reported in parentheses, and allow for clustering within school. A Bonferroni correction for five hypothesis tests changes the significance of the first result from the 99 percent level to the 95 percent level. Both the Sidak and Holm-Bonferroni corrections yield identical results.

***Significant at the 99% level.
