Grading Policies

Grading System

For credit courses:

  • A+, A  (Highest passing grade)
  • A-
  • B+
  • B
  • B-
  • C+
  • C
  • C-
  • D+
  • D
  • D-  (Lowest passing grade; passing minimal objectives of the course)
  • E    (Conditional failure; failure to achieve minimal objectives but only to such limited extent that credit can be obtained by examination or otherwise without repeating the course. This grade represents failure in the course unless changed during the following semester. It cannot be improved to a grade higher than “D”)
  • F   (Failure to achieve minimal objectives of the course. The student must repeat the course satisfactorily in order to establish credit in it)

Please note, Faculty & Instructors have the option of assigning plus/minus grades.  You can check with your instructor for the grading scale for your particular course.

For incomplete work:

  • I Incomplete; no grade. A record of work which was interrupted by unavoidable absence or other causes beyond a student’s control, which work was passing at the time it was interrupted, and the completion of which does not require the student to repeat the course in order to obtain credit. The incomplete may also be used to delay the awarding of a grade in courses (e.g., self-paced courses, mastery courses, and practicums) the completion of which normally requires one semester, but the structure of which allows specified additional time. An instructor may require the student to secure the recommendation of the Vice Chancellor for Academic Services that the circumstances warrant a grade of I, PI, SI, or E, he/she shall file in the Registrar’s Office a statement of the reason for the grade and what is required of the student to achieve a permanent grade. He/she shall also indicate the grade the student has earned on the work completed, and the weight to be given to the remainder of the work in computing the final, permanent grade. The student must achieve a permanent grade in the course no later than the 12th week of the second subsequent semester of enrollment, or the I grade will revert to a failing grade. The removal of a conditional or an incomplete grade at a later date does not affect probation status. If the student is not enrolled for a period of three years following the semester in which the incomplete is given, then the incomplete grade will be permanent. The grade will not revert to a failing grade, nor will the student be able to earn credit for the course by completing the work.
  • PI Incomplete; no grade. Same as I, except that the student was enrolled under the pass/no pass option.

Directed Grades

The registrar is directed to record the following grades and symbols under special circumstances in lieu of semester grades. The registrar may require from the faculty such information as he or she needs and on such forms as the registrar shall prescribe.

  • W Withdraw; a record of the fact that a student was enrolled in a course and withdrew or canceled the course after the second week.
  • WF Withdraw Failing; a record of the fact that a student was enrolled in a course and withdrew or canceled the course after the fourth week at which time, according to a statement from the instructor, the student was not passing in his/her work. A grade WF may be directed by the Committee on Scholastic Delinquency and Readmission. It does not affect index computations.
  • WN Withdraw Not Passing; the same as WF for a course taken under the pass/no pass option except that it does not affect index computation.
  • IF Unremoved Incomplete Failing; for a course in which a student received an I grade, a directed record of the student’s failure to achieve a permanent grade by the 12th week of the second subsequent semester of enrollment. This grade counts in all respects as a failing grade.
  • IN Unremoved Incomplete – Not Passing; for a course taken under the pass/no pass option and in which a student received a PI grade, a directed record of the student’s failure to achieve a permanent grade by the 12th week of the second subsequent semester of enrollment. Otherwise the same as IF except that it does not affect index computations.

Pass/No Pass

The university faculty has also provided that a student may take a limited number of courses under a dual grading system of Pass/No Pass. Each student operating under this option and earning a Grade of A, B, or C, shall receive a pass; those earning less than a C shall receive a no pass. The specific regulations stipulating when this option may be used are determined by the school administering the curriculum of the student.

Scholastic Index

Purdue University operates on a 4.0 grading scale:

A+, A 4.0 x semester hours = index points
A- 3.7 x semester hours = index points
B+ 3.3 x semester hours = index points
B 3.0 x semester hours = index points
B- 2.7 x semester hours = index points
C+ 2.3 x semester hours = index points
C 2.0 x semester hours = index points
C- 1.7 x semester hours = index points
D+ 1.3 x semester hours = index points
D 1.0 x semester hours = index points
D- .7 x semester hours = index points
E, F, IF 0.0 x semester hours = index points
P,N,I,PI, SI, W,WF, WN,WU, IN,IU,AU,NS are not included
