test scores, some recent studies do show positive
effects on graduation rates, parent satisfaction, community college enrollment, and other nonachievement - based outcomes, but it is unclear if these outcomes are lasting and valid.23 For example, research shows that nationally, graduation rates for students in public schools and peers participating in voucher programs equalize after adjusting for extended graduation rates.24 Some critics suggest that private schools may graduate students who have not successfully completed the full program.25 Also, in regard to parent satisfaction, while some studies do show greater satisfaction
among parents whose children participate in voucher programs, the most recent evaluation of the D.C. voucher program shows that any increase in parent or student school satisfaction is not statistically significant.26
