I'm looking forward to tonight's Frontline on Michelle Rhee's tenure as DC schools' chief. In preparation for that, Rhee's group, Students First, has released a "report card", which ranks each state's school policies and the extent to which they conform to those of Students First.
There are two problems with this. The first is that the report card is funded by two groups, the American Enterprise Institute and the Thomas B. Fordham Institute. I'd never heard of Fordham, so I went to Wikipedia and found that the primary policy of that group is the elimination of teacher unions. The group actually produces studies which purport to show that students perform better in schools where the teachers aren't unionized. The problem with these studies is that they are described as "laughable" and "silly".
Now Doug Henwood has done the work to show us what's wrong with the report card. The highest-ranking state, Louisiana, has some of the worst outcomes in the country. You can look at his post here.
