Incompletes should be used sparingly if at all. It is a far better to plan ahead and use advising and academic support resources to ensure finishing the coursework on time.
If the work for a course is incomplete as a result of the student's unexplained failure to hand in assigned work or to take the final examination at the regularly scheduled time, the instructor will issue a grade of F for the course. If the Incomplete is not made up by the deadline below, it will become an F.
The decision to grant an Incomplete or not is solely that of the instructor teaching the course.
The Incomplete is made up only when the official grade is received by the College Office. After a grade is converted to an F, the instructor may choose to change it up to two full semesters (excluding summer) after the term in which the course was taken. The instructor who gives an evaluation, exam or course grade has sole authority for changing such evaluation, exam or course grade provided the instructor remains on the faculty (or the emeritus faculty) of the University of Pennsylvania.
In cases in which faculty appointments have terminated, or faculty have resigned or are deceased, sole authority for changing an evaluation rests with the undergraduate chair of the relevant department.
