This may be a moment of opportunity. Of course, picking up the good teachers while they're available assumes that you can tell who they are from resumes & recommendations. Objective measures would make that easier too. In general I was thinking about the long-term equilibrium, in which case getting bad teachers out of one district isn't good enough; you have to get them out of the field, and attract new, better replacements in. I doubt there's that much labor mobility, so using VAM to improve the learning process, making all teachers better, might be more productive. Good point. This may be a moment of opportunity.

Many of these teachers were let go based on tenure rather than results. No better time to use value-added measurement than in the current recession ! I do believe your analysis is correct when the economy (and the pool of available teachers) is closer to full employment.
