Application for admission to the Graduate School at this university must be made on forms provided by the Director of Admission. An applicant whose undergraduate work was done at another institution should request that two copies of undergraduate transcripts and degrees be sent directly to the Dean of Graduate School. Both the application and transcripts must be on file at least one month prior to the registration date, and must be accompanied by a nonrefundable ten-dollar check or money order to cover the cost of processing the application. Students who have already been admitted to the Graduate School but were not enrolled during the previous semester should reapply for admission using a special form available in the office of the Graduate School. It is not necessary for students who have previously been denied admission to resubmit transcripts; however, new application forms must accompany all requests for reconsideration. Applications should be submitted at least eight weeks in advance of the session in which the student wishes to enroll. Students who have already been admitted to the Graduate School
