Seeking Practical Uses of the NYC VAM Data???

A short while back, in a follow up post regarding the Chetty/Friedman/Rockoff study I wrote about how and when I might use VAM results, if I happened to be in a decision making role in a school or district:

I would want to be able to generate a report of the VA estimates for teachers in the district. Ideally, I’d like to be able to generate a report based on alternative model specifications (option to leave in and take out potential biases) and on alternative assessments (or mixes of them). I’d like the sensitivity analysis option in order to evaluate the robustness of the ratings, and to see how changes to model specification affect certain teachers (to gain insights, for example, regarding things like peer effect vs. teacher effect).

If I felt, when pouring through the data, that they were telling me something about some of my teachers (good or bad), I might then use these data to suggest to principals how to distribute their observation efforts
