The "I" grade indicates that the student's work to date is of passing quality but is incomplete for reasons acceptable to the instructor. The student must have substantial equity in the course with no more than four weeks of course work remaining to be completed. A grade of "I" will be assigned only in case of illness or for unusual or unforeseeable circumstances that were not encountered by other students in the class and that prevent the student from completing the course requirements by the end of the semester. Prior to assignment of the "I" grade, the student and instructor should reach a written agreement concerning the work still outstanding. The work must be completed by no later than the end of the sixth week of class of the next regular (fall or spring) semester. A grade of "I" may be removed with the approval of the academic unit head and the Associate Dean of the Undergraduate College, after all remaining work is completed and the instructor assigns a regular grade. If no regular grade has been received in the Office of Student Records and Registration by the above deadline, the "I" grade will revert to a grade of E.
