The head of one voucher school recently under investigation fled the scene and was arrested in Texas. When you're promoting a market approach to education, a 25 percent failure rate is an important piece of information. Two of them are Afro-centric and one is centered on Hispanic culture. Although there are some whites in the voucher program, GPD drop these students from their analysis. The GPD study stands in relation to all other studies of this issue in the same way that an analysis purporting to show that the earth is flat stands in relation to hundreds of years of scientific evidence showing that the earth is round.
School vouchers are an important and contested public policy issue.
Children's futures are on the line, and citizens and policymakers depend on honest evaluations to help them make wise decisions. Given the stakes, it behooves researchers involved with this issue to do their work with the utmost care and integrity. The work of GPD ignores this ethical necessity.
