The Thomas B. Fordham Institute, one of the nation’s leading advocates for school choice, commissioned a study of Ohio’s voucher program. To what must have been their surprise and disappointment, the study concluded that students in voucher schools perform worse than students in public schools.

I was a founding member of the Thomas B. Fordham Foundation–now the Fordham Institute–and I will affirm that TBF told unpleasant truths, even to its own disadvantage and the disadvantage of its causes. I left the board in 2009, after I fell away from choice, competition, and accountability as answers to the needs of America’s students.

This is a study that does TBF proud, even though it disproves its foundational belief in school choice.

Here are the key findings:

There are now some 18,000 students receiving publicly funded vouchers in Ohio.

The voucher students are overwhelmingly low-income and minority, but somewhat higher-achieving and less economically disadvantaged than students who were eligible for vouchers but chose not to use them.

The public school students improved their performance, and the study attributes their improvement to the voucher program that they did not enroll in.

The effects: “The students who used vouchers to attend private schools fared worse on state exams compared to their closely matched peers remaining in public schools. Only voucher students assigned to relatively high-performing EdChoice eligible public schools could be credibly studied.”

The study was led by Dr. David Figlio of Northwestern University.

This study adds to the mountain of evidence that public schools in Ohio outperform the charter sector and the voucher sector. Does anyone think that policymakers and legislators in Ohio will do anything to support their much-maligned public schools?
