I’m surprised anyone was surprised by the recent flat-lining of scores on the NAEP 4th grade math test. The rate of improvement in NAEP scores has been declining since No Child Left Behind was passed, and the recent results are consistent with that trend.
But what really amazes me is that so many people think the solution is just to tweak NCLB! The unstated assumption here is that federal policy is a key determinant of educational achievement. That’s rubbish.
