Voucher advocate proposes "no fiddling with the data."
Another recent study of 13,577 schools shows that public schools hold their own against private schools. The report calls the public school students’ scores “statistically significantly higher,” because 10 points is generally considered to represent one grade level’s difference. “This analysis makes it appear that there isn’t anything magical in private schools that leads to a significant difference in achievement,” Mr. Lubienski, co-author of the study, said.
In what has to be one of the most nonsensical quotes ever, Joe McTighe, Executive Director of the Council for American Private Education had this response to Education Week, “When you look at the data as is without any fiddling, students in privates outperform those in publics by a wide margin,” he said.
Let me interpret "without any fiddling." It means "don't look too closely at the data." When they broke the data down and compared students with similar backgrounds, public schools outperformed private schools.
Look for a huge push from voucher advocates in the next year. Indiana has already vowed to do so. I think there will be more desperation to do so soon because the longer time goes on the better and more thorough the research base will get. And that....might not be what private schools and voucher advocates really want.
