Tying them directly indeed seems like a bad idea (like pretty much any other naive reputation score), but that doesn’t mean you have to give up on the feedback

Tying them directly indeed seems like a bad idea (like pretty much any other naive reputation score), but that doesn’t mean you have to give up on the feedback mechanism. Just set a threshold - such as “scores an average of < 4/10”. If the score is below that threshold, invest a little more time and effort into getting more detailed evaluations and figuring out why the score is low and whether it’s a genuine problem with the professor vs something like their having high standards and lazy students. Then train or fire as appropriate.

Strict thresholds don't usually work. My school had public metrics, and teachers preferred classes made a huge difference. The teachers that taught the harder classes (component design rings a bell) always got significantly lower scores than the ones teaching easier classes (physics I, circuits for Mechanical Engineers)

  That’s why you don’t use the threshold to trigger anything more punitive than further investigation. And sure, tune the threshold to the department. But also consider that maybe teaching is better on average in some departments than others. (For instance, the drop-off in teaching quality from high school to college in my experience was enormous in math and arts but slight in both sciences and humanities. Which seems to me more like a problem with the math and art departments’ approaches to hiring or teaching than with math or arts as subjects.)

    That’s why you don’t use the threshold to trigger anything more punitive than further investigation. And by "you", you mean "no one ever". Teacher evaluations have immediate and universal impact. There is essentially no filter and no interpretation on this. It's like tweets. Once a social signal is out-there, public, everyone is acting on the implications regardless of hypothetical mitigating factors. A lot of people talk about this stuff in the abstract, as some hypothetical, like we'll do this and we'll have safeguards in place. The news is, this is how things have been for college teachers for a while. You get an evaluation and it has an impact and there's no mitigation and no contextualizing.
