Will value-added do as little for the nation as it did for Tennessee?

Given that 'value-added' methods of assessing teachers are known to be unreliable, is there yet a way to use them in evaluation? Here's a case for it by an assessment expert from Tulane University.

Here's the crazy story of Kim Cook, a teacher at Irby Elementary, a K-2 school which feeds into Alachua Elementary, for grades 3-5, just down the road in Alachua, Fla. She was recently chosen by the teachers at her school as their Teacher of the Year but got a bad evaluation based on data that has nothing to do with her.
