Cato Institute’s Corey DeAngelis refutes the idea that the evidence for school choice is “mixed.”  DeAngelis writes,

Seventeen experimental studies of the effects of private school choice programs on student achievement exist in the U.S. today. As shown in this graphic, the majority of the 17 studies find statistically significant positive effects on student test scores, while only two detect negative effects. And it is important to note that the two studies finding negative impacts are first-year results.

He also examines the effect of school choice on traditional students, civic engagement, crime, and racial integration.  DeAngelis concludes, “The evidence suggests that private school choice improves test scores, high school graduation rates, tolerance, civic engagement, criminality, racial integration, and public school performance. The evidence on private school choice is far from mixed. Anyone claiming that “the evidence on private school choice is mixed” is either uninformed or not grappling fully with the research. It is simply not true.”
