Thomas Paine recommended vouchers to help parents afford private schools for their children more than 200 years ago. While most college students today use vouchers to attend public or private colleges and universities, the concept remains needlessly controversial when it comes to parents using them for their school-age children.

For example, in a recent Washington Post article Emma Brown recently claimed school choice hasn’t worked based on evidence from New York City, where students are no longer assigned to public high schools based on their zip codes.

For starters, the Big Apple is hardly, as Brown calls it, “a real-life laboratory for questions of school choice” just because in 2004 the city deigned to allow parents of eighth-graders to choose up to 12 public high schools to attend out of a possible 400.

Currently, more than half of all states have parental choice programs that include private schools – not just public schools. New York isn’t one of them.

But Brown’s own evidence shows that empowering parents over their children’s education works. According to Brown, as of 2015 NYC’s overall public high school graduation rate has improved steadily and now exceeds 70 percent. Even neighborhood-based racial graduation rate gaps have diminished. Yet because they exist, school choice must be a failure. Brown seems to be implying (although she doesn’t say so explicitly) that returning to the old way of assigning students to schools would level the playing field.

It likely would…but not in a positive way since assigned schooling minimizes the likelihood students will be able to attend schools that are the best for for them. And, by removing competition for students schools have little (if any) incentive to customize instruction to individual students’ needs…. read more here
