The final MET study supposedly show that value-added modeling really does work and that test scores really do show who the best teachers are.

But Bruce Baker says the study is full of holes and circular reasoning.

When Bill Gates and the top executives at Microsoft put their own children in schools that use test scores as the measure of good teaching, then we will know that they believe in what they advocate.

This is the kind of school that the connoisseurs prefer. True, the school is in Silicon Valley, not Seattle, but I expect the education at the Waldorf School of the Peninsula looks a lot like the Lakeside School (where Bill Gates went) or Maumee Valley Country Day School (where Michelle Rhee went).
