Full-time students who wish to attend a course without receiving academic credit or a grade may, with the approval of the instructor, audit the course without charge. The student registers for a vacation Block. The instructor and the student determine at the start the requirements for attendance and participation, and whether or not the audit is to be recorded on the student's transcript. If the audit is to be recorded, during the first three days of the Block the student files with the Registrar the appropriate form signed by the instructor to certify that the student intends to fulfill the requirements of the audit. At the end of the Block the instructor certifies that the audit has been fulfilled and the student receives the grade of AU on the transcript. If the student has not fulfilled the requirements, then the Registrar records a vacation Block . Audited courses, whether recorded or unrecorded, may not be used to satisfy degree or major requirements.
