WASHINGTON — The school choice movement, which germinated 50 years ago in free-market economist Milton Friedman's fertile mind, recently counted its largest victory. The Indiana Supreme Court unanimously upheld the constitutionality of the state's school voucher program. Under it, more than half a million low- and middle-income Hoosier students are eligible for state aid to help pay for a private or religious school.
This is what school choice has traditionally lacked: scale.
Since the first experiment in Milwaukee in 1990, voucher programs have been resisted by a powerful combination of interests. Teachers' unions have fought what they regard as a diversion of resources from public education — while conveniently undermining a source of professional competition and accountability. But this opposition has been empowered by the skepticism of many suburban parents, who have paid a premium to buy homes in better school districts. When educational outcomes become less connected to the ZIP code you inhabit, some property values will decline.
It is a paradox Friedman would have appreciated. Vouchers have been blocked by unions resisting market forces and by suburban parents reflecting those forces.
This has generally relegated vouchers to the margins of education reform, in underfunded micro-programs aimed at the very poorest. The District of Columbia's scholarship program, for example, capped participants at 3 percent of the student population while increasing funding for public education. The political price of providing vouchers to disadvantaged children has often been to shield public schools from even the mildest competitive pressure.
But even small, restricted choice programs have shown promising results — not revolutionary, but promising. Last year a group of nine leading educational researchers summarized the evidence this way: “Among voucher programs, random-assignment studies generally find modest improvements in reading or math scores, or both. Achievement gains are typically small in each year, but cumulative over time. Graduation rates have been studied less often, but the available evidence indicates a substantial positive impact. …”
Only recently, a few innovative governors — particularly former Gov. Mitch Daniels of Indiana and Gov. Bobby Jindal of Louisiana — have decided to bring this promise to scale. The Louisiana Supreme Court will soon issue a judgment on Jindal's program. The Indiana verdict could hardly have been more favorable to the choice movement. The court found that Indiana is serving valid educational purposes both by maintaining a public schools system and by providing options beyond it. And it held (as the U.S. Supreme Court ruled in 2002) that including religious schools as an option does not establish religion. “Any benefit to program-eligible schools, religious or non-religious,” the Indiana court concluded, “derives from the private, independent choice of the parents.”
