Grade reassessment is the process of reviewing the calculation of grades, or the methods and criteria used to establish final grades, or the application of academic regulations or procedures in course grading. The outcome of a grade reassessment may be a grade increase, a grade decrease, or no change to the grade. The detection of errors or omissions in the calculation of final grades will result in the assignment of a revised grade. Students normally initiate grade reassessments, but instructors may initiate this process. In the event that the reassessment results in a change in grade, the department chair may arrange for the review of the grades of other students in the course and ensure that other grades are changed, if necessary.
