Changes in grades after degree conferral should be permitted only to correct the transcript. An instructor’s error in assigning a grade or tardiness on the part of the instructor in initiating the change of grade process (provided the change was warranted prior to degree conferral) are acceptable reasons to effect such a change.
No additional work by the student after degree conferral is permitted to “correct” a transcript. Of course, a “system” error, such as an improper transfer of grades from instructors to the computer database, may always be corrected. There is no time limit for correcting grading errors on the transcript.
