Notes: The first three columns of this table report means and standard deviations for all variables in each group. An F-test of joint significance is used to test the hypothesis that: β₁ = β₂ = β₃ for OLS regressions (with school level clustered robust standard errors) of the following form: Variable = β₁×(Full Treatment) + β₂×(Screen Only) + β₃×(Control) + Strata fixed effects + ε.
