There are significant differences between the various schools and the way they treat both students and teachers.
At the one four year university I have an office (I have to share but who cares) and a secretary who will do things for me if I ask nicely
There, the exams are already there under lock and key. If I had not been able to get to class there, the secretary would have gotten the test and either proctored it herself or the department chair would have done it.
At the Community College I have a mailbox. It is not secure and I can not leave any personal belongings or handouts anywhere. I am not treated as a professional. When I offered to have the exam e-mailed to them they simply refused. There is NO area where the exam could be "left" for someone else to proctor it. If I have one student who cannot make an exam time, I have to return on a different day to do it.
Forget, a week! I barely had a week to give the exam, grade it, calculate final grades, complete EOF, ADA and a huge pile of other forms and submit the grades!
But there was no need to "scan" the document, it was a file that could either be attached or simply pasted into the body of the e-mail... No special equipment needed that the student did not already need to be in the school anyway.
(Why am I on here? I take breaks from the grading.... If I don't I go bonkers!)
