Random assignment studies are the gold standard of social science research because they allow researchers to isolate the effect of the intervention, similar to medical trials where doctors randomly administer a drug to some patients but not others in order to determine the drug’s effectiveness.
Third Way, however, ignores the gold standard studies, omits the positive findings for low income and minority students from the very research it cites, and points instead to analyses that compare apples and orangutans. For example, Third Way points to a 2013 Politico article that claimed Milwaukee voucher students underperformed their public school counterparts on standardized tests. However, it is misleading to compare the mostly low-income voucher students to the general student population, which includes students from wealthy families. Previous random assignment studies by researchers at Princeton and the Brookings Institution found that Milwaukee voucher students scored significantly higher than the control group on math and reading exams. Moreover, the average cost per pupil in Milwaukee’s public schools is more than double the average $6,442 voucher.
Third Way concedes that there is “some evidence that voucher programs may be correlated with modest gains in graduation rates” but claims that “it is unclear whether the increase is a direct result of the voucher programs themselves or other kinds of reforms.” Their claim is based on a 2011 literature review, but they are apparently unaware that a 2013 gold standard study of Washington D.C.’s voucher program found that voucher students graduated at a rate 12 percentage points higher than the control group. In addition, a 2012 random assignment study by researchers at Harvard and Brookings found that African-American scholarship students in a New York City pilot enrolled in a four-year college at a rate 8.7 percentage points higher than the control group.
2. School choice makes schools directly accountable to parents.
While regulations vary considerably, most school choice laws (particularly scholarship tax credit laws) do not impose the public school testing regime on private schools accepting school choice students. Third Way asserts that this is “incredibly problematic” because it is “impossible to tell how voucher students or specific groups among them, like students with disabilities or students of color, are faring from school to school—let alone compared to their non-vouchered peers.” However, imposing standardized tests has the potential to stifle the very the diversity and innovation that gives choice its value.
When tied to the “annual goals” and potential “repercussions” that Third Way advocates, standardized tests drive what is taught, when it is taught, and how it is taught. Such so-called “accountability” measures create a powerful incentive for schools to conform, depriving parents and students of the ability to choose schools that chart a different course.
It is inappropriate to impose an accountability system designed to regulate a monopoly on a market. Private schools are directly accountable to parents, who have the ability to vote with their feet if the school fails to meet their needs. By contrast, public schools are accountable to politicians and bureaucrats, not parents. Indeed, many low-income families have no financially viable options besides their assigned district school. Without the crucial feedback loop that direct accountability to parents provides, states and localities (and even the feds) have imposed numerous regulations to improve quality, generally with little success. Unfortunately, these top-down regulations have become synonymous with “accountability” when they are but a pale imitation of direct accountability to parents.
3. There is no evidence that school choice programs “wreak havoc” on school district budgets.
Third Way laments that school choice could “destabilize district financial planning.” It is telling that they don’t point to a single example. Even more telling, their concern assumes that there would be a mass exodus from the public schools if families were given the option to leave and take the funds dedicated to their child with them. As David Boaz once observed, “Every argument against choice made by the education establishment reveals the contempt that establishment has for its own product.”
4. School choice empowers low-income families.
Third Way asserts that “letting the money follow the child” would “divert limited … resources away from districts needing financial assistance the most.” This assumes that a lack of resources is what ails low-performing schools. However, if funding were the main driver of performance, then at about $30,000 per pupil, Washington, D.C.’s public schools would be among the best in the nation instead of the worst.
There is little compelling evidence that resources drive performance. A 2012 report on international and state trends in student achievement by researchers at Harvard, Stanford, and the University of Munich found that “Just about as many high-spending [U.S.] states showed relatively small gains as showed large ones…. And many states defied the theory [that spending drives performance] by showing gains even when they did not commit much in the way of additional resources.”
Moreover, the available evidence suggests that the positive impact of choice and competition outweighs any potentially negative impact from lower resources. Twenty-two out of 23 empirical studies found that the performance of students at public schools improved after the enactment of a school choice law. One study found no statistically significant difference and none found any harm. School choice programs empower low-income families to choose the schools that work best for their children, which means that public schools have to be more responsive to their needs.
5. The public increasingly wants more choice.
Third Way claims “Americans overwhelmingly reject the idea that vouchers are an effective way to repair our country’s education system.” As evidence, they cite a 2013 PDK/Gallup poll, which found that 70 percent of Americans opposed vouchers. However, in a 2014 survey by Education Next and Harvard University’s Program on Education Policy and Governance, 60 percent of Americans favored scholarship tax credits and 50 percent favored universal school vouchers.
Moreover, Americans are likely to support school choice at even higher levels over time. A 2014 poll by the Friedman Foundation for Educational Choice found the highest levels of support for school choice policies among Americans aged 18–35, with 74 percent favoring scholarship tax credits and 69 percent supporting vouchers. Even the 2013 Gallup poll found that 75 percent of 18–29 year olds and 59 percent of 30–49 year olds support school vouchers.
Federal vouchers are still a bad idea.
School choice programs benefit participating and public school students, increase accountability to parents, empower low-income families, and have the support of a growing majority of voters. So why not support a federal school choice law?
Even setting aside the constitutional issues, there are pragmatic reasons for opposing increased federal involvement in America’s education system. As David Boaz explained more than a decade ago in the Cato Handbook for Congress, the case against federal involvement in education:
