Vouchers and Other Diversions of Public Funds to Private Schools

What the research says about private school vouchers

Vouchers are state-funded certificates that are used to pay tuition to private schools. Mississippians have been so opposed to using taxpayer dollars to fund private schools that our constitution bans these voucher payments. Savvy folks who have long sought to privatize our public schools now are attempting to circumvent the constitution – and the will of the people – by using tax credits and education savings accounts to funnel state tax dollars to private schools.

The most recent research on the academic impact of private school vouchers finds that voucher students experience significant losses in achievement. Prior research showed that gains in achievement were about the same for low income students receiving vouchers as they are for comparable public school students.1

Long-term studies of voucher programs in Milwaukee2, the oldest school choice/voucher program in the U.S., Cleveland3,4, and the District of Columbia5 found no advantage in academic achievement for students attending private schools with vouchers.

In Louisiana, students using vouchers to attend private schools were 24-50% more likely to score below Basic (failing) in the four tested subjects than comparable students in public schools.6  By the end of year 4 of Louisiana’s voucher program, voucher students “performed noticeably worse on state assessments than their control group counterparts.”7

Ten years of longitudinal data on Ohio’s EdChoice voucher program found persistently lower achievement for voucher students relative to public school peers in both math and English language arts, with the greatest disparity in math (2003-2004 through 2012-2013).8

Milwaukee, which introduced vouchers in 1990 and by 2014 provided them to 25,000 students annually, requires its voucher students to take the same Wisconsin state tests used in the public schools. This allows a comparison of private school voucher students and public school students, all of whom reside within the city of Milwaukee. Performance results from the 2013-2014 school year showed slightly lower proficiency rates for voucher students in both math and reading as compared to their public school peers.9

Annual studies of Florida’s tax credit (voucher) program showed negligible changes for private school voucher students.  Of the 158 private voucher schools reporting more than 30 students, only 18 schools achieved statistically significant, though small, gains in reading and math from 2011 – 2014. Another 31 schools produced statistically significant losses over the three-year period. Most schools’ voucher students performed about the same as they had in previous years, neither gaining nor losing ground when compared to their peers (Florida no longer reports comparative scores for in-state public school and voucher students).10

Competition and choice have failed to produce achievement gains in the countries that have tried the approach, while global leaders in achievement (Korea, Finland, Hong Kong, Singapore, and Canada) have succeeded by building capacity within public schools. A study of Indiana’s voucher program found that all of its core concepts are contrary to these best practices of high-achieving nations – improving teacher quality and instructional practices, encouraging mentoring and collaboration, and investing sufficient resources to implement changes.11

A real-world example of how competition affects achievement

School choice proponents claim that the mere existence of competition from voucher-receiving private schools generates improvement in nearby public schools. Milwaukee offers a real-world example of how a “competitive marketplace” of education options affects achievement in traditional public schools. After 25 years of voucher competition, more than 80% of the city’s public school and voucher students were not proficient in reading and math.12 Moreover, Milwaukee Public School District was among the lowest ranking in NAEP scores of all large urban districts in the U.S.13

Tax credits: Subsidizing private education for wealthy families

By allowing tax credits for contributions to private schools, the Legislature is telling taxpayers, “You can just write a check to your private school instead of paying your taxes, and we will deduct that amount from the taxes you owe the state.” It’s a tax write-off for private school patrons, while the state foots the bill for private schools. It is a clear circumvention of the intent of our constitution.

This scheme of subsidizing private education with public funds is happening in a big way in Mississippi. In 2019, the Legislature passed the Children’s Promise Act, a bill providing tax credits for donations to agencies that provide services to foster children. The bill was presented and voted on without disclosure of a separate statute within it that provides tax credits for donations to private schools. The measure has been renewed each year along with increases in allowable tax credits. In 2022, legislators voted to shift $9-million in taxpayer funds to unaccountable private schools through the program. Private schools can receive up to $405,000 in public funds per school, annually beginning in 2023, with no restrictions on expenditures and no reporting requirements. 

ESAs: Shifting public funds to unaccountable private schools

Education savings accounts (ESAs) originated in model legislation from the American Legislative Exchange Council (ALEC). ESAs are designed to circumvent state law by handing parents state tax dollars that have been diverted from public schools in exchange for a commitment from the parents to use the funds for any of a variety of “educational” purposes, such as private schools, tutoring, cyber schools, textbooks, etc. There is little to no accountability or oversight for the expenditure of these funds.

In more recent “universal” ESA programs, the vast majority of vouchers go to students who never attended public schools. States including Arkansas, Arizona, Florida, and Iowa, have seen relatively low participation from former public school students, meaning these states are instead subsidizing tuition for children who always have been enrolled in private schools.

Bottom line regarding diverting public funds to private schools

Study after study conducted in multiple states confirm that schemes to shift public funds to private education provide no achievement benefit for the students they purport to help, while depleting funds intended for public schools. Voucher students perform about the same, and often worse, in unaccountable private schools than they did in public schools, and public schools are left with diminished resources.
