Kinda backwards in graduate school. Research universities often treat the students as cheap labor and don’t weigh their outcomes for tenure decisions. I think there should a be a five year after graduation delay where graduate mentors are evaluated in hindsight after the mentee can see if it was just hard or if someone was a jerk. It does inherently add an aspect of employment to the evaluation, but if the university agrees that’s more their responsibility (UrgentlyFiring) and actually invests in placement systems I think it’d work well.
