NEPC responds to a vicious (and inaccurate) Wolf attack on Ravitch. I have posted photos of the pages in question where Dr. Wolf (or someone) changed the data he reported…

Yesterday, Patrick Wolf published a vitriolic attack on me and on the National Education Policy Center.
This was in response to a post I had published saying that vouchers had failed in Milwaukee. They are supposed to “save minority students from failing schools,” but they do no better and sometimes worse than public schools. I cited Wolf’s evaluation, state test scores (which showed no edge for voucher students), and the fact that 75% of the voucher students in his study did not remain in the voucher schools to graduate. The 75% attrition rate appears in Wolf’s report. I did not know that he subsequently lowered the attrition rate to 56%, although that too is a pretty staggering attrition rate. I also noted that Wolf recently wrote an editorial in the Minneapolis Star-Tribune chastising his home state of Minnesota for not requiring more school choice. This caused me to question his “independence” as an evaluator of school choice, since his article advocated for more school choice. And this is why he is so angry at me.
