Study: Learning loss persists for voucher students

Indiana students who used vouchers to transfer to private schools fell behind their public-school peers academically, according to a study by researchers at the universities of Kentucky and Notre Dame.

And the loss of learning persisted for several years. That’s significant, because a preliminary version of the study, made public a year ago, suggested voucher students might catch up if they stayed in private schools for three or four years.

“We don’t see that rebound effect” in the published results, co-author and University of Kentucky professor Joseph Waddington told me. “The test scores remained where they were.”

The study, by Waddington and Notre Dame’s Mark Berends, was published last week in the Journal of Policy Analysis and Management. It found voucher students saw their scores on the state’s ISTEP-plus mathematics tests fall 0.15 standard deviation behind their peers the year they moved to a private school.
