A new RCT look at educational vouchers
A new RCT look at educational vouchers: "From Matthew M. Chingos and Paul E. Peterson (pdf):
In the first study using a randomized experiment to measure the impact of school vouchers on college enrollment, we examine the college-going behavior through 2011 of students who participated in a voucher experiment as elementary school students in the late 1990s. We find no overall impacts on college enrollments but we do find large, statistically significant positive impacts on the college going of African American students who participated in the study. Our estimates indicate that using a voucher to attend private school increased the overall college enrollment rate among African Americans by 24 percent."
