Why is a six year graduation rate being normalized?

That doesn’t sound like a workable system. When is a drop “too late”? The drop deadline at UC Berkeley, for example, is the 4th Wednesday after classes start. The add period extends to the Friday after that, so it’s technically not too late for someone to add. (Realistically, though it wouldn’t be a great idea unless a student was attending all along).

And if you shorten the drop period, you end up with adverse consequences. If it was only two weeks, students might not even have gotten a single graded assignment back before the drop period expired.
