The 123s of School Choice: What the Research Says About Private School Choice Programs in America, 2023 Edition

An EdChoice report is billed as an overview of the varied and often contested research on outcomes in school choice programs, which it defines narrowly as vouchers plus voucher-style programs that provide public funding for private schools. The report examines research on student achievement, access, competitive effects, and other topics, purportedly to help policymakers and parents weigh the benefits and costs of these voucher programs. It claims to show that school choice “works,” based on finding more positive than negative studies, yet uses a simplistic, flawed approach that obscures important differences in studies and can create a misleading narrative about the research evidence.

Martin F. Lueken and Michael Q. McShane
K-12 Without Borders: Public School Students, Families, and Teachers Shut In by Education Boundaries

A report oversimplifies important equity issues as problems of school zone boundaries. Despite noting mixed research results on how school choice affects housing patterns, the report assumes that eliminating school zone boundaries will necessarily result in wealthy families voluntarily relocating into poorer neighborhoods—ignoring the documented reality that many parents work to ensure that school district boundaries replicate segregation and inequity. In addition, the report offers no solutions to such concurrent problems as transportation for students choosing distant schools or housing for residents displaced by gentrification. The report’s illogical assumptions, lack of evidence, sleight of hand, and improbable leaps of logic make its advice to policymakers useless.

NEPC Review: Toward Equitable School Choice (Hoover Institution, November 2020)

Paul E. Peterson
Toward Equitable School Choice

A report from the Hoover Institution seeks to offer evidence-based guidance for policymakers in shaping more equitable outcomes from school choice programs. This review examines the report's claims, its representation of the research, and its use of research in forming those recommendations. The review finds that although the report is useful as a snapshot of the current status of choice programs in the United States, its use of research is often problematic. Some of the research is misrepresented, many claims are made without citations to evidence, and some of the recommendations bear no connection to the evidence provided in the report. As such, the report is, as intended, a political guidebook for conservative policymakers that fails to offer evidence-based guidance on making choice more equitable.

NEPC Review: 12 Myths and Realities about Private Educational Choice Programs (Institute for Justice, August 2017)

Tim Keller
12 Myths and Realities about Private Educational Choice Programs

For over a quarter-century, researchers and others have vigorously investigated and debated the impact of school vouchers and voucher-like programs (such as education savings accounts and tuition tax credits/deductions). The result is a developed and sophisticated research literature on different aspects of these programs. But a report from the Institute for Justice does not take advantage of this body of research, instead offering little more than a simplistic and one-sided treatment of the empirical record. Setting out 12 “myths” about vouchers, the report then proceeds to systematically dismiss each “myth” in turn by presenting only evidence—much of it highly questionable—on the advantages of vouchers. Based largely on previous reports from other advocacy groups that curated evidence in order to present vouchers in a most positive light, the report then repeats many of those claims, even when flaws in those reports have already been publicly explained. In doing so, the report makes claims that are not supported, and in fact sometimes contradicted, by evidence in the sources it cites. The report provides a textbook case of echo-chamber advocacy, drawing primarily on reports from other voucher advocates. Consequently, it offers nothing useful in furthering our understanding of school vouchers. 

NEPC Review: Do Impacts on Test Scores Even Matter? (American Enterprise Institute, March 2018)

Collin Hitt, Michael Q. McShane, & Patrick J. Wolf
Do Impacts on Test Scores Even Matter?

A report from the American Enterprise Institute (AEI), Do Impacts on Test Scores Even Matter? Lessons from Long-Run Outcomes in School Choice Research, examines whether student achievement scores on math and English language arts tests align with “long-run” attainment outcomes such as high school graduation rates, college enrollment, and college graduation rates. Drawing on a systematic review of the literature, it concludes that the impacts of school choice programs on test scores are not well connected to such attainment outcomes, which are presented as more positive. This review considers two issues with the report: consistency and evidence. Regarding consistency, the report’s suggestion that achievement scores should play a smaller role in determining the efficacy of school choice models represents a stunning effort to move the goalposts in search of new justifications for supporting their preferred policies. After decades of pro-school-choice research and advocacy promoting test score comparisons with public schools as the primary measurement for evaluating school choice models (e.g., charters and school vouchers), the AEI report now suggests that less attention be given to these learning outcomes. Regarding evidence, the AEI report is riddled with numerous internal inconsistencies in its discussion and treatment of a set of studies that were selected by questionable methods. In view of the 180-degree turn based on questionable evidence, the report — despite the authors’ assertions — is of little use to policymakers.

NEPC Review: Differences by Design? Student Composition in Charter Schools with Different Academic Models (American Enterprise Institute, February 2017)

Jenn Hatfield and Nat Malkus
Differences by Design? Student Composition in Charter Schools with Different Academic Models

A report by the American Enterprise Institute (AEI), Differences by Design?, compares differences in approaches and demographics between and among charter school models and local “traditional public schools.” Using three national data sets, the report effectively captures the national universe of charter schools. It empirically demonstrates that cream-skimming occurs and that charters segregate by income, special education, race and ethnicity, in that different demographic groups attend different types of charter schools. Charter schools, the authors contend, provide differentiated and “innovative schooling options” through varied academic models that cater to, and ultimately reflect, parental choices for their children. The resulting de facto segregation is presented as a benign byproduct of beneficial choices differentially associated with different racial and ethnic groups. They contend this is “in line with a properly functioning charter sector.” Unfortunately, the report does not demonstrate familiarity with the research on parent decision-making or with the extensive research suggesting that charter schools are not particularly innovative in the curricular or instructional options. Despite what the report claims, traditional public schools do, in fact, offer various academic model specializations like the ones offered by the charter schools. Ultimately, the report’s dismissive characterization of de facto segregation in charters, as a benign byproduct of parental choice, is at odds with the purpose and aims of equitable public education.

A Win-Win Solution: The Empirical Evidence on School Choice
The Participant Effects of Private School Vouchers across the Globe: A Meta-Analytic and Systematic Review

Two reports claim to offer empirical support for the efficacy of voucher programs that allow parents to use taxpayer dollars to send their children to private schools. One report (A Win-Win Solution) is the latest in a series from the Friedman Foundation for Educational Choice. The Friedman report reviews studies purporting to show positive impacts from voucher programs in the US. The other report (The Participant Effects of Private School Vouchers across the Globe) is from the Department of Education Reform at the University of Arkansas. The authors of the Arkansas report conducted a limited meta-analysis of US and international studies of voucher programs. The two reports share a positive view of the impacts of vouchers, and both focus on randomized studies of those effects. Both reports are marred by a number of serious problems and errors, including misrepresentations of the research literature, a failure to acknowledge the limitations of their approaches, not addressing the shortcomings of the theoretical underpinnings of vouchers, and the use of methods that bias the selections of the studies they utilize. The Friedman report is a rudimentary “vote-counting “analysis of an extremely narrow set of 18 studies using a biased counting system. The Arkansas meta-analysis aspires to be “global,” but despite identifying over 9,000 potential studies for the analysis, ultimately uses only 19, almost half of which were conducted by the Arkansas authors or their associates. Moreover, the “global” meta-analysis only encompasses three countries (one of which is consistently misspelled). Together, their manifold serious flaws undercut the trustworthiness and usefulness of these reports.

Review of The Texas Economy and School Choice

Arthur Laffer
The Texas Economy and School Choice

In a recent report, The Texas Economy and School Choice, written by Arthur Laffer for the Texas Association of Business and the Texas Public Policy Foundation, Laffer evaluated the effect of the proposed Taxpayer Savings Grant Program (TSGP)—essentially a universal voucher program designed to provide school choice to every student in Texas. Laffer concludes that by raising graduation rates, improving education achievement, and thus increasing human capital, the TSGP would substantially raise wages and income for working families, thereby improving economic growth in Texas. In this review, we highlight two profoundly problematic areas of the report. First, Laffer’s assertions about the educational benefits of choice represent a severe overreach with and misapplication of the available research. Second, the author’s economic estimations are over-generalized and heavily biased towards those families who already have the wealth to choose and relocate. The report applies simplistic economic logic to education and fails to consider all but an extremely narrow and inappropriate slice of research on education, making the report unsuitable as a basis for public policy decisions. 

NEPC Review: Pluck & Tenacity: How Five Private Schools in Ohio Have Adapted to Vouchers (Thomas B. Fordham Institute, January 2014)

Ellen Belcher (main report), Aaron Churchill and Chad Aldis (foreword, executive summary)
Pluck & Tenacity: How Five Private Schools in Ohio Have Adapted to Vouchers

The new Fordham report, Pluck & Tenacity, examines the impact of school vouchers on five private schools in Ohio. While the journalist who authored the report is primarily interested in the effect on this small set of schools, we focus here on an underlying assumption asserted in the executive summary of the report: that because of vouchers, “school outcomes will improve.” As presented in this report, this assumption about the beneficial impacts of vouchers is a case-study in how to engage in slanted selection and interpretation of research evidence. As we show in this review, the totality of three endnotes used in the report reflect not just an incomplete picture of the research literature on vouchers, but an extreme case of cherry-picking sources to support a contested policy agenda. Moreover, even with the few sources cited to put voucher outcomes in a favorable light, the report cherry-picks the findings that suit Fordham’s agenda, while ignoring the findings from those very same sources that do not support—and even contradict—the premise. Thus, the report is grounded in a twice-skewed and intellectually dishonest view of the research on vouchers and their academic outcomes. The subsequent journalistic celebration of five schools in Ohio then continues this unsystematic treatment of evidence, amounting to little more than cheerleading for vouchers.

Review of Report Card on American Education

Matthew Ladner and David J. Myslinski
Report Card on American Education: Ranking State K-12 Performance, Progress, and Reform

The 18th edition of the American Legislative Exchange Council’s (ALEC) Report Card on American Education: Ranking State K-12 Performance, Progress, and Reform draws on ratings from market-oriented advocacy groups to grade states in areas such as support for charter schools, availability of vouchers, and permissiveness for homeschooling. The authors contend that these grades are based on “high quality” research demonstrating that the policies for which they award high grades will improve education for all students. This review finds that, contrary to these claims, ALEC’s grades draw selectively from these advocacy groups to make claims that are not supported in the wider, peer-reviewed literature. In fact, the research ALEC highlights is quite shoddy and is unsuitable for supporting its recommendations. The authors’ claims of “a growing body of research” lacks citations; their grading system contradicts the testing data that they report; and their data on alternative teacher research is simply wrong. Overall, ALEC’s Report Card is grounded less in research than in ideological tenets, as reflected in the high grades it assigns to states with unproven and even disproven market-based policies. The report’s purpose appears to be more about shifting control of education to private interests than in improving education.

NEPC Review: A Win-Win Solution: The Empirical Evidence on How Vouchers Affect Public Schools (February 2009)

Greg Forster
A Win-Win Solution: The Empirical Evidence on How Vouchers Affect Public Schools

Advocates of vouchers argue that nearby public schools will be forced to compete for students, leading to improvements for voucher users and non-users alike. Critics worry that the students who use vouchers to leave public schools will have parents with higher levels of education and be less expensive to educate, and that losing these students will cause those schools to enter spirals of decline. This new report purports to gather all available empirical evidence on the question of the competitive effects of vouchers, finding a strong consensus that vouchers help public schools. But the report, based on a review of 17 studies, selectively reads the evidence in some of those studies, the majority of which were produced by voucher advocacy organizations. Moreover, the report can’t decide whether or not to acknowledge the impact of factors other than vouchers on public schools. It attempts to show that public school gains were caused by the presence of vouchers alone, but then argues that the lack of overall gains for districts with vouchers should be ignored because too many other factors are at play. In truth, existing research provides little reliable information about the competitive effects of vouchers, and this report does little to help answer the question.

Promising Start: An Empirical Analysis of How EdChoice Vouchers Affect Ohio Public Schools

A Friedman Foundation report attempts to find empirical support for the contention that competition from private schools, through voucher programs, improves the effectiveness of public schools. In the first year of Ohio’s new EdChoice voucher program, the report claims to have found substantial academic gains at public schools exposed to the possibility of losing students to vouchers. Despite being presented as scientifically rigorous, the report suffers from serious methodological shortcomings.

Despite being presented as scientifically rigorous, the report suffers from serious methodological shortcomings. The analysis uses weak variables and an incorrect approach to measuring academic gains and tries to make claims based on cherry-picking uneven results. Moreover, even accepting the study’s analysis, it produces a finding very much at odds with the author’s intent: that vouchers are not likely to close the achievement gap between high- and low-performing schools.

NEPC Review: The ABC's of School Choice (September 2007)

The Milton and Rose Friedman Foundation
The ABC's of School Choice

A new annual report from the Milton and Rose Friedman Foundation is designed as a resource to provide ammunition for persuading people as to the merits of school choice. While there may indeed be a number of reasons to argue for school choice, this handbook shoots blanks. The report provides updated information on thirteen states and the District of Columbia with policies that approximate the Friedman Foundation's voucher-based version of school "choice." While the descriptive compendium of information is mostly accurate and somewhat useful, the report begins and ends with "Frequently Asked Questions," where the Foundation seeks to interpret the research on school choice issues for the lay reader. As might be expected from a voucher advocacy organization such as this, the report relies on a highly selective sub-sample of studies. The research referred to in the report tends toward non-peer-reviewed studies of questionable quality from other advocacy organizations, while ignoring evidence in these and other higher quality studies that questions the Foundation's unequivocal support for vouchers. Evidence — particularly on the issue of achievement — is consistently abused in this report, both by misrepresenting individual studies (including those by voucher advocates) and misrepresenting the general body of research on choice. In short, for those hoping to learn more about the issue, this one-sided report does a poor job of even representing only one side of the debate.
