The responsibility for academic evaluation and grade assignment resides with the faculty member teaching the course. If you believe that you have been graded unfairly, you should first appeal the grade to your professor. If you are dissatisfied with the outcome of your initial appeal, you may appeal through administrative channels (either your department chair, academic dean or the grade-appeals committee).
The steps for an informal as well as formal grade appeal can be found in the Student’s Rights and Responsibilities Handbook. Click on the link below to access the handbook:
