Missing Grade (M grades)
If an instructor does not award a grade during the open grading window, an M grade (Missing) is automatically assigned. An M grade will change to a grade of X one term after the M was initially assigned. Once converted to an X, the grade cannot be changed.
A graduate student will not be certified for graduation who has any M grades in PSU graduate courses that could potentially be letter graded, even if the courses are not applied to the student's degree.
