Supporters of the Florida Tax-Credit Scholarship (FTS) program are understandably disappointed that the state senate abandoned legislation to expand the program on Thursday. The FTS assists low-income families that want to enroll their children in private schools by offering tax credits to donors of nonprofit scholarship organizations. This year, the state’s only active scholarship organization, Step Up For Students, was able to aid more than 60,000 students but there were not enough funds to aid the more than 30,000 additional applicants. The proposed expansion would have provided enough funds to aid about 6,000 more students. The bill’s withdrawal therefore leaves 6,000 students without the funds they need to attend the school of their choice.

However, the disappointment should be tempered by a large measure of relief. While the legislation contained several praiseworthy changes and eliminated some red tape (including a requirement that would-be scholarship recipients spend a year in a government-run school first), legislative negotiations threatened to add a poison pill that would have severely affected school autonomy and parental choice.

The FTS currently mandates that all participating schools administer a nationally norm-referenced test. Nevertheless, Florida Senate President Don Gaetz insisted that the FTC expansion bill include a provision requiring that scholarship students take the Florida Comprehensive Assessment Test (FCAT), which is soon to be replaced by a Common Core-aligned assessment.

While the existing mandate is unnecessary because private schools are already directly accountable to parents, it still allows schools and parents some measure of flexibility in deciding how best to measure performance. By contrast, the proposed state testing mandate would have forced all schools into a uniform testing regime. Since tests dictate what is taught, when, and how, this mandate would have induced conformity at the expense of diversity and innovation. As explained in the open letter on choice and accountability that the Cato Institute recently issued along with the Heritage Foundation, Friedman Foundation for Educational Choice, and others, such mandates undermine the central purpose of educational choice:

Educational choice has also been repeatedly shown to produce far higher levels of parental satisfaction than does centrally planned schooling. That’s because choice empowers parents to find the best education for their children, and test scores are not their only consideration. Research shows that many parents care more about safety and discipline, graduation and college acceptance rates, and moral values.

Dictating uniform standards and tests threatens those other valued features by redirecting educators’ focus from serving families to catering to bureaucrats. It also contributes to a culture of “teaching to the test” that has already resulted in several large-scale public-school cheating scandals.

Children are not interchangeable widgets that can be beneficially fed through their education on the same conveyor belt. Even within a single family, children often learn different subjects at different speeds. Myriad new options are arising in response to that reality that allow students to learn at their own pace in every subject, helping all to fulfill their individual potential — the very antithesis of uniform government mandates.

Fortunately, the FTS already contains an “escalator” provision that allows it to grow over time, albeit not as quickly as it would have under the expansion bill. Hopefully, Florida legislators will take a second look at some of the important reforms that would have expanded access to the program. Meanwhile, other states that are considering scholarship tax credit legislation should learn from Florida’s experience. Design matters.
