“The two reports focus on randomized studies of the effects of vouchers on education outcomes and both conclude that vouchers have positive impacts. However, both reports are marred by a number of serious problems and errors, including not addressing the shortcomings of the theoretical underpinnings of vouchers, methods that bias the selections of studies to review, misrepresentations of the body of evidence represented in the research literature, and failure to acknowledge the limitations of their approaches.
