The University is going to have classes on some holy days. You may be religious and want to observe your religious holiday or custom. Do it. But first, let your teacher know and ask how you can otherwise account for the work or experience that you will miss. And have this conversation before the event. Stamps faculty will help you out, but they’re going to be less accommodating when you spring something on them at the last minute. Or the week after.
The University’s policy is given below.
It is the policy of the University of Michigan to make every reasonable effort to allow members of the University community to observe their religious holidays without academic penalty. Absence from classes or examinations for religious reasons does not relieve students from responsibility for any part of the coursework required during the period of absence. Students who expect to miss classes, examinations, or other assignments as a consequence of their religious observance shall be provided with a reasonable alternative opportunity to complete such academic responsibilities.
It is the obligation of students to provide faculty with reasonable notice of the dates of religious holidays on which they will be absent. Such notice must be given by the end of the fourth week of a full term or by the end of the third week of a half term. Students who are absent on days of examinations or class assignments shall be offered an opportunity to make up the work, without penalty, unless it can be demonstrated that a makeup opportunity would interfere unreasonably with the delivery of the course. Should disagreement arise over any aspect of this policy, the parties involved should contact the Assistant Dean (Joann). Final appeals will be resolved by the Provost.
