We teachers have enough on our plates helping our students, fighting the cheaper, but equally dangerous knock-offs of D.C.'s IMPACT evaluation system, and working for humane and evidence-driven methods to improve our schools. We shouldn't waste our strength worrying about whether evidence that supports the accountability hawks is exaggerated or not.
We're a nation that's coming to respect statistics. Billy Bean convinced us that better statistics could beat bigger payrolls in sports. Nate Silver helped humble Karl Rove's money machine with better statistics. Maybe it's time to take a more careful look at the international test statistics judging how good our nation's schools are.
