Lawmakers have demanded lots of proof to determine whether preschool helps kids before deciding to significantly boost its funding, despite dozens of studies showing that students who attend high-quality preschool perform much better in school than students who don’t.
Yet they’ve requested no long-term study of another similarly designed, tuition support program — vouchers for private schools, a program that launched in 2011 and has seen hundreds of millions of dollars in state support. In research that does exist on the effectiveness of vouchers in other states, results are mixed, at best, and show relatively small effects on kids.
