While I agree completely that attracting good teachers is difficult, and we need to spend more time doing that - in part by paying them more money - I don't think there's any evidence for the idea that somehow tenure attracts good teachers. In fact, I think the evidence is to the contrary.

A trial is a powerful vehicle to explain things. It is the most time that anybody spends really thinking about one thing. Unless you are the analyst on the National Security staff that's assigned to monitor Putin, and that's all you do, day in and day out, very few people ever spend the time on a single subject that is spent during trial.

In any profession, whether it's teachers or doctors or lawyers, the more we say we're not going to evaluate those people on the merits, I think that's when the profession goes into decline.
