The minimum grade for credit is "C". Although not specifically stated in the graduate catalog, the Department also considers "C" as the minimum level for non-graduate credit courses. If a student repeats a course, the last grade earned is used in calculating the graduate average. A grade of "I" is given for course work not completed within the semester in which the student registered for the course. This grade indicates that, although the student was doing satisfactory work, the student was unable to complete the course for some reason beyond his/her control. The Department recognizes that at the graduate level a student occasionally may not be able to complete the course work within a given semester, but considers repeated grades of "I" as inadequate progress. According the Graduate School requirements, a student must remove an "I" grade within 3 semesters (including summer semester) of enrollment following assignment of the "I" grade or it automatically becomes an "F". Grades of "S" (Satisfactory) and "U" (Unsatisfactory) are given to some graduate level courses. These grades must be given to all GEOG 9000 (Doctoral Research) and 9300 (Doctoral Dissertation) registrants. Failure to maintain an overall "B" (3.00) average can result in dismissal from the degree program. Graduate School policy is that a student with a cumulative graduate grade point average below 3.00 for two consecutive semesters is placed on academic probation. The student then must make a 3.00 or better semester graduate average each succeeding semester that the student's overall cumulative average is below 3.00. Probation ends when the cumulative average is 3.00 or above. A student is dismissed if a 3.00 semester average is not maintained while on probation. Departmental policy is that if the student's grade average for any semester falls below a "B", the student is placed on probation for the succeeding semester. During the probationary period, students who do not maintain "B" level work are assigned to the end of the list of students holding assistantships and are subject to loss of previously offered financial support.
