Across large swathes of the US, state governments are rapidly redrawing the boundary between public education and private choice, allowing families to tap public funds to pay for private school tuition, homeschool materials, and education services once considered firmly outside the state’s remit. What began as targeted programmes for low-income families or children with disabilities has, in just four years, evolved into a sweeping experiment in universal eligibility.Yet even as participation surges, the most basic question remains stubbornly unanswered: What, exactly, is this transformation delivering for students, for public schools, and for academic outcomes?
A policy shift with unusual speed
According to an Education Week analysis, 18 states now have laws on the books that make virtually all K–12 students eligible for public funding to use outside the traditional public school system. Every one of those states adopted universal eligibility within the past four years, a pace of policy change that is rare in education, a sector usually marked by incrementalism.Texas is set to become the most consequential test case. Applications open next month for a new education savings account programme expected to cost roughly $1 billion annually. Under the plan, families can receive up to $10,500 per student for private education expenses, with awards rising to $30,000 for students with disabilities. Given the state’s size, even modest uptake could reshape national enrollment patterns.Advocates argue the momentum reflects pent-up demand. “Families want flexibility,” school choice supporters often say, pointing to dissatisfaction with district schools after the pandemic and a desire for customised learning environments. The numbers suggest something more structural than a momentary backlash.EdChoice, a pro–school choice advocacy group that tracks state programmes, estimates that 1.5 million students are using private school choice options this academic year across 30 states. That figure stood at about 1 million just 18 months ago and fewer than 500,000 as recently as the 2018–19 school year. By comparison, roughly 49.3 million students attended US public schools last year.In Arizona and Florida, more than 10 percent of K–12 students now participate in private school choice programmes, a threshold that signals not a niche alternative but a parallel system.
Growth without clarity
Despite the scale and speed of expansion, researchers caution that the evidence base has not caught up. Part of the problem lies in design. The new generation of universal programmes differs sharply from earlier voucher initiatives, which were typically limited to low-income families or students in struggling schools. Today’s policies serve a broader, and often more affluent, population, making comparisons to older studies increasingly tenuous.Academic outcomes are especially difficult to assess. Of the first eight states to launch universal private school choice programmes, only two, Indiana and Iowa, require participating students to take the same state assessments as their public school peers, according to FutureEd’s analysis. Four others, Arkansas, Florida, Ohio, and West Virginia, mandate testing but allow families or schools to choose from a menu of approved national exams, complicating any effort to draw direct comparisons.In the remaining states, there is little publicly comparable data at all. The result is an accountability gap that critics say is baked into the policy design.
Signals beyond test scores
Supporters counter that academic achievement should not be reduced to standardised test results alone. On longer-term measures, some choice programmes show more promising signs.An Urban Institute analysis published last April examined Ohio’s EdChoice private school scholarship programme during the years 2008 to 2014, when it was limited to low-income students from low-performing public schools.The study found that participating students were more likely than their public school peers to attend college and earn a degree, a result frequently cited by advocates as evidence that school choice can alter life trajectories, even when test score gains are modest or mixed.Still, researchers are careful to stress context. Ohio’s programme during that period was far narrower than today’s universal models, and its findings may not translate cleanly to states where middle- and upper-income families now dominate participation.
The public school question
What happens to public schools as funds follow students elsewhere remains one of the most politically charged aspects of the debate.Critics warn that universal choice accelerates enrollment declines already afflicting many districts, particularly in rural areas and cities with shrinking populations. Supporters respond that public schools must adapt to competition and that funding should reflect parental decisions rather than institutional preservation.So far, the data are inconclusive. Enrollment shifts vary widely by state and locality, and in many places, private school capacity limits how many students can realistically exit the public system.What is clear is that another inflection point is coming. A new federal policy, set to take effect next year, will allow families to receive private school scholarships funded through tax credits, adding yet another layer to an already complex landscape.
An experiment still unfolding
For all the political certainty that surrounds universal school choice, its real-world consequences remain unsettled.Participation is rising, public dollars are flowing into private education at unprecedented levels, and the traditional boundaries of public schooling are being redrawn in real time. Yet the evidence on academic impact, equity, and long-term system effects is still fragmentary, shaped as much by what states choose not to measure as by what they do. In education, that may prove to be the most consequential choice of all.
