EAST LANSING, Mi. (Sept. 8, 2008)— A new report from the Friedman Foundation for Educational Choice claims to find evidence that Ohio’s private-school voucher program spurs public schools to improve achievement. A review of the report finds numerous flaws that seriously undermine the research.

The report, “Promising Start: An Empirical Analysis of How EdChoice Vouchers Affect Ohio Public Schools,” was reviewed for the Think Twice project by Professor Christopher Lubienski of the University of Illinois, a nationally recognized expert on school choice research.

“Promising Start” examines Ohio’s EdChoice program, which offers vouchers of $4,375 or more to allow up to 14,000 students enrolled in “chronically under-performing” public schools to instead attend private schools at taxpayer expense. The report asserts that there is empirical support that the voucher program, by fostering competition with public schools, improves those public schools’ performance, thereby providing an indirect benefit to those students who remain in the public schools. In particular, it claims that in EdChoice’s first year, students experienced 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,” Lubienski writes. “The analysis uses weak variables and an incorrect approach to measuring academic gains, and it tries to make claims based on cherry-picking uneven results.”

“Instead of being empirically based, the report’s assumptions appear to be more statements of belief based in a rudimentary and simplistic view of economic behavior in markets for education,” Lubienski writes. “The Friedman report selectively focuses on studies—no matter what the quality—that appear to support its agenda. In doing so, it leaves out much high-quality research, much of it peer-reviewed, that seriously questions the assertion that the threat of losing students has a positive impact on public schools.”

“In view of the announced advocacy mission of the Friedman Foundation for Educational Choice regarding vouchers, and the notable flaws on this report, it is better read as a statement of belief than as an empirical analysis,” Lubienski writes.
