Touro-NY did it just a few years ago. From what I remember, the Admissions Dean left before he got fired.
Stanford also had an overenrollment episode a few years ago, and it led to the firing of the Admissions dean.
Just to clarify, it's not the Dean of the med school whose head will roll, but the Admissions dean.
Just as with the airlines, schools will encourage people to defer, with either partial or even full tuition breaks. TouroNY did the opposite...they found some pretext to rescind admissions. This was one of the reasons they were on my Bad Boy list for a while.
I'm sure the wise
@gyngyn can tell a few more juicy stories!
