For the past thirty years, school choice advocates have claimed that the best way to improve education was to give families public money to send their child to a private or religious school. The very fact of “privateness,” they said, meant better quality. This turns out not to be the case. Students never receive a voucher that is enough to pay for elite private schools. Typically, the voucher schools are lesser quality than the public school the cHold leaves, because voucher schools are not required to have certified teachers. In recent years, numerous studies show that children who leave a public school and go to a voucher school lose ground academically.

This study was published in 2018. Its findings are consistent with studies of voucher effects in the District of Columbia, Ohio, Indiana, and other states. Voucher schools are free to teach scientific nonsense and fake history. In Florida and elsewhere, they are free to discriminate against groups of people they don’t like.

Atila Abdulkadiroğlu, Parag A. Pathak, and Christopher R. Walters write in the Journal of the American Economic Association that participation in Louisiana’s voucher program “lowers math scores by 0.4 standard deviations and also reduces achievement in reading, science, and social studies. These effects may be due in part to selection of low-quality private schools into the program.”

Despite the negative effects of vouchers, Betsy DeVos, Charles Koch, and a host of school choice advocacy groups have continued to demand more and more funding for low-quality, unaccountable voucher schools. This funding is subtracted from public school funding, through a variety of schemes. Whether it’s a tax creditor a “scholarship,” individuals and corporations are diverting money to private schools that belongs in the state coffers to support public schools.
