Quantile treatment effect estimates of the impact of a voucher offer on reading National Percentile Rankings at baseline

Notes: Figure shows QTE for the effect of being offered a voucher for private school on baseline reading National Percentile Ranking scoress from the Iowa Test of Basic Skills. Estimates are weighted using inverse propensity score weights. Weights are 1/p̂ for treatment observations and 1/(1 − p̂) for control observations, where p̂ is generated from a logistic regression of treatment status on baseline demographics, sample design variables, and baseline test scores. 95% CIs are obtained by bootstrapping families with replacement. Data from the New York City School Choice Scholarships Program evaluation conducted by Mathematica Policy Research. Baseline scores unavailable for kindergarten students.
