An important article that calls “Bull!” at the current mania for teacher evaluation appears here. The key point comes at the end:

Rubinstein writes that “the high correlation in this plot reveals that the primary factor in predicting the scores for a group of students in one year score is the scores of those same students in the previous year score.”

Basically, student performance is linked to what students have done, not what teachers do.
