A week ago, the Atlanta Journal Constitution published an on-line op-ed critiquing Chile’s nationwide public-and-private school choice program. In a letter to the editor, I objected to several of the op-ed’s central claims. The authors responded, and the AJC has now published the entire exchange. A follow-up is warranted, which I offer here:
Comment on the Gaete, Jones response to my critique:
Their response consists chiefly of “moving the goalposts”—changing the issue under debate rather than responding to the critique of the original point. The first claim in their original op-ed to which I objected was that “there is no clear evidence that [Chilean] students have significantly improved their performance on standardized tests.” In contradiction of this claim I cited the study “Achievement Growth” by top education economists and political scientists from Harvard and Stanford Universities. That study discovered that Chile is one of the fastest-improving nations in the world on international tests such as PISA and TIMSS—which were specifically designed to allow the observation of national trends over time. It is hard to conceive of clearer evidence that Chilean students “have significantly improved their performance”, contrary to the claim of Gaete and Jones.
