Past grading codes no longer in use:
Prior to Fall 1985, the University granted semester credit on a three-point scale. Students who began their academic career under the three-point scale were allowed to continue under this system. Beginning in Fall 1985, the University granted semester credit on a four-point scale.
Additionally, the following grades codes may appear on official academic transcripts but are not currently used by the University:

| IN (Incomplete) | 0.00 |
| WD (Withdrawal) | 0.00 |
| WF (Withdrawal Failing) | 0.00 |
| WP (Withdrawal Passing) | 0.00 |
