NAEP results: not definitive

The 2007 NAEP results are presently available on line. They are not yet available in print. As per past years, the Bush administration is making claims about the scores which are not supported by the evidence.
Here's a more intelligent article on the NAEP results than I've seen elsewhere. It brings out most of the important points, in my view. To wit:

1. The recent gains are quite modest, especially when it comes to closing "achievement gaps."
2. The upward trends in math and in 4th grade reading started well before NCLB took effect and appear to have leveled off a bit since that time.
3. The NAEP data offer no clear conclusions for policy -- it doesn't prove that NCLB is either helping or hurting.
