This question stems from a personal situation however I will attempt to make it generalizable if I make a post. Let me make it clear that I am not the one tasked with making this decision, I am seeking a consensus for what could be reasonably expected in a situation like this.
In short, I have a generalizable situation in which one is considering retroactively dropping a student's grade(s) because new information has been made available.
The reason I am hesitant to post this question is because it may be opinion based or broad/open-ended since every institution has a different, albeit similar in many cases, policies regarding situations like these. Usually the policies are intentionally vague and leave a lot up to interpretation in order to give the person tasked with this decision flexibility. However, in spite of this large and open ended grey area, there are some situations that would in general clearly necessitate a dropped grade (or something similar), e.g. a student becomes comatose in the middle of a semester. I believe this situation falls into that category. Furthermore, I would argue it is a question regarding "requirements and expectations of students" albeit on a more administrative level.
Should I just ask it here in the meta with the discussion tag or can I post it in the regular exchange?
