Studies Bring Bad News for Vouchers… With Lots of Caveats
We’ve covered quite a bit of positive research regarding private school choice in recent months. Back in May, I wrote about a meta-study by researchers at the University of Arkansas that found positive effects from vouchers in the U.S. and a couple of other countries. The following month, we dug into the Friedman Foundation’s latest review of random-assignment studies on private school choice programs in the United States. Fourteen of the 18 studies included in that review found positive effects for at least some groups of students. Two found no visible effects, and two more—both from Louisiana—found significant negative effects. As I’ve said before, there are good reasons to believe that program design and implementation issues played a role in the negative findings in Louisiana. Now, though, I’m sorry to report that I’ve become aware of less easily explained bad news on voucher programs in Ohio and Indiana. But don’t fret just yet; there are some major caveats that need to be considered before we start jumping to broad conclusions. Buckle up, today’s post will be a long and nerdy one.
