The debate over school choice is often treated as ideological. The research record — thirty years of it — suggests it should be treated as empirical.
This piece reviews what the peer-reviewed evidence actually shows on school choice: where it is strong, where it is mixed, and what it means for donors who are evaluating the Education Freedom Tax Credit as a giving vehicle.
What the Long-Run Studies Show
The most rigorous research on school choice comes from randomized controlled trials — the same methodology used in clinical medicine — conducted on voucher programs in Milwaukee, Washington D.C., and New York City. These studies follow students over years and decades, tracking outcomes that matter beyond test scores.
The findings are consistent and striking.
53%
Reduction in drug convictions among Milwaukee voucher recipients vs. control group
21 pts
Higher high school graduation rate for D.C. Opportunity Scholarship recipients
86%
Reduction in property damage convictions among Milwaukee program students
These are not marginal effects. A 53% reduction in drug convictions and an 86% reduction in property damage convictions among Milwaukee voucher recipients compared to the control group are the kind of outcomes that change the trajectory of communities, not just individuals. School choice, at its best, is not just an education intervention. It is a social mobility intervention.
Academic Achievement: A More Nuanced Picture
On standardized test scores, the research is more mixed — and that’s worth acknowledging directly. Some studies show modest short-term gains for voucher recipients. Others show neutral effects. A few studies of specific programs in specific contexts show initial negative effects that diminish over time as students adjust to new environments.
Two things are worth noting about this mixed picture. First, studies that show neutral or modest effects on test scores typically also show positive effects on graduation rates and civic outcomes — suggesting that the academic environment matters beyond what standardized tests capture. Second, the choice available to students in voucher programs is often a dramatic improvement over the alternative, even when test score gains are modest.
“Approximately 90% of American students are eligible for scholarships funded through this program. The question isn’t whether it reaches your community. The question is whether your community reaches back.”

Civic and Social Outcomes
Some of the most compelling school choice research looks beyond academics to civic participation, tolerance, and community engagement. A series of studies found that private school choice leads to meaningfully better civic outcomes — including higher rates of voting, volunteering, and political tolerance among program graduates.
For donors evaluating the EFTC as a long-term investment, this body of research matters. A student who graduates, votes, volunteers, and participates productively in civic life is a different kind of outcome than a student who scores slightly higher on a standardized test.
What the Research Doesn’t Resolve
Honest Limitations of the Evidence Base
- Most long-run research comes from urban programs. The Milwaukee, D.C., and NYC studies reflect specific demographics and school contexts. The EFTC is a national program — its effects at national scale will need to be studied as the program matures.
- Program design matters. Not all school choice programs produce the same outcomes. Which designs work best, for which student populations, in which contexts is an active area of empirical inquiry.
- Long-run effects on traditional public schools remain contested. Some research suggests modest positive spillover effects from competition; other research is more skeptical. This remains an open empirical question.
What the Evidence Means for EFTC Donors
The Education Freedom Tax Credit creates a national vehicle for donors to support school choice at scale. The evidence that school choice — when well-implemented and reaching students who need it — produces positive outcomes is substantial. It is not a speculative bet. It is a bet supported by three decades of data from programs that have been rigorously evaluated.
Donors who give through AFC Scholarship Fund are adding their resources to a body of work with a documented track record. Since 2021, AFC has invested more than $11 million and supported 157,000 students across 12 states. The EFTC multiplies the reach of that work by creating a tax-advantaged giving vehicle that makes the decision to give easier for more donors.
