The grade of Incomplete (I) is a temporary mark given for coursework of acceptable quality which students, through no fault of their own, are unable to complete; it is not given for neglected work. A grade of Incomplete also indicates that more than three-fourths of the work of the course has been completed. Coursework must be completed within six weeks of the start of the following Fall or Spring semester (see deadlines posted in the Academic Calendar). Under certain circumstances, students may petition instructors to have completion deadlines extended to, at the latest, the end of the semester in which incomplete grades are due. If the work is not completed by the end of the period specified, the temporary mark is changed to the grade indicated by the instructor, or if no grade has been indicated the mark is changed to an F. When coursework in which a student has received an Incomplete has been made up, the final grade is entered with I and the letter grade (for example, IA).
