There’s an old legal proverb about how to win a court case: “If the law is on your side, pound the law. If the facts are on your side, pound the facts. If neither is on your side, pound the table.” In this factually-challenged attack on school choice, two lawyers at the UNC Center for Civil Rights do a great deal of table pounding.
Despite mountains of evidence to the contrary, the lawyers charge that school choice programs don’t work and that they increase racial segregation. For example, they claim:
…in states with [school choice] programs, student achievement at the private schools is no better, and often worse, than in the public schools. In fact, in Milwaukee and Cleveland, whose voucher programs are the country’s longest running, traditional public school students outperform voucher students on available proficiency measures.
Even read in the most charitable light, the lawyers misleadingly compare apples and orangutans. Participants in school choice programs are generally more disadvantaged than the general population, so it is absurd to compare their average performance against the general population, which includes all the students in wealthy “public” school districts (where low-income parents have been arrested for trying to enroll their kids). Government school advocates rightly object when someone compares average private school performance to average government school performance. The private schools outperform government schools on average, but because both parents and the private schools select each other, the comparison breaks down. The same is true here.
A meaningful comparison requires a randomized-controlled trial, which is the gold standard of social science research because the process of randomization allows researchers to compare like against like and to isolate the effect of the “treatment” (in this case, the offer of a school choice scholarship). Fortunately, there have been 12 such studies addressing this very question from highly-respected institutions like Harvard University and the Brookings Institution. Eleven found that school choice programs lead to positive student outcomes, including higher academic performance and higher rates of high school graduation and college matriculation. One study found no statistically significant difference and none found a negative impact.
