Three cheers to John Tierney for shredding the ridiculous conclusions that people were drawing from the lame study comparing public and private schools that came out last week.

Spinning a Bad Report Card

Thanks to a new federal report comparing public and private schools, there’s no doubt that public schools have one huge advantage: the leaders of their unions are unrivaled masters of spin.

They didn’t merely celebrate the report’s release on Friday, they complained that the Bush administration tried to bury it by releasing it for the weekend. They spun so well that the report was treated as a public-school triumph that “casts doubt on the value of voucher programs,” as The Wall Street Journal described it.

But if anything, the report from the Education Department did just the opposite. It concluded, after compensating for socioeconomic differences and other factors, that public-school students score slightly better on tests in fourth grade, while private-school students score slightly better in eighth grade. Given a choice, would you rather be ahead in the fourth inning or later in the game?

But even if you ignore that trend, even if you focus on the overall similarity of the scores in both types of school, that’s still bad news for public schools. Their students ought to be scoring higher if you believe in the unions’ favorite prescription for improving education: more money...
