| These suggestions of "pay for results" have a complicated history. I suggest anyone interested actually search the literature on it. Ever since I saw the critique of the 2012 NYC value added measure results, which shows VAM scores uncorrelated between different classrooms of the same teacher [4], I have been very skeptical that any kind of incentive pay will work. (Also, this NYT article is pretty damning considering the source. [3]) The question is not whether VAM can work, it is a question of does a particular implementation work. The paper [1] is a classic (search for it). In this particular case: the exact method is not clear but it sounds like there is no adjustment for prior achievement, so all teachers of advanced classes will automatically get the bonus? What if instead what is being measured is the change from year to year? Same result: in this case history is an excellent predictor of the future.
