Lostaccount, I agree with some of what you say but I know of cases where accommodations were applied retroactively. But to be clear by that I mean that a certain class was dropped and the grade expunged ( I just heard via PM from a student I advised via PM last month, who did this) but more likely, yes, a college will allow a medical withdrawal (including retroactively) with the record expunged.
I completely agree however, with you and with many disability offices, that a student should withdraw and take a leave if the need for accommodations means any substantial financial or administrative burden, or poses a change to the academic program. My own daughter, who has serious health problems, would not tolerate asking for accommodations if the need arose more than a couple of times a semester. She took two medical leaves in college, and the college really respected her for respecting their curriculum and trying to do her part. Also, if an accommodation for a serious medical event gave her two weeks to finish an assignment past due, she did it in two days. Many students are like her and abhor accommodations, but there are times when one accommodation or allowed withdrawal from a class can save a kid from a tangent in their lives.
Clinical depression, anxiety and /or ADHD are all legitimate disabilities if properly diagnosed and if treatment is in the works. A student cannot go to a dean after failing and say, “gee I was depressed.” But if the student was seeing a therapist the whole time, there is some possibility of raising that issue, though registration with the disabilities office would have been a help.
More importantly, a new diagnosis of ADHD mid-semester would mean new hope of doing better, presumably, and if the record shows that, the school might be encouraged to give another chance. Again, this needs to be supported by a professional and by efforts to treat.
The sad thing here is that it sounds like not enough communication or documentation happened before the dismissal.
There are wide variations from school to school on all this. Leaves from school or withdrawals from a class ARE granted at some schools in a situation like this. But also, at other schools, they are not. The main suggestion I have is to get a professional involved, communicate with a dean, don’t rely on one of those sad letters from the student saying how sorry she is and she is now doing x,y,and z and will do better.
If the dismissal holds, it is NOT a disaster. The student has learned something and there are many ways to continue on a path of school or work or both. But I do think it is worth a shot in this case, mainly because the diagnosis and treatment of ADHD was midsemester with evidence of improvement. But clearly no one is really helping this student in terms of advocacy- and it would have been better to deal with this during the disaster, not after, clearly.
