When space is available and the Department and Dean consent, any person may audit a course by paying the $10 per course audit fee. An individual sixty-five years of age or older is exempt from paying the fee. Credit is not awarded for any audit course. Individuals who audit courses do not submit papers, take examinations, participate in discussions, or receive evaluations in courses audited. Those wishing to audit may register only after late registration but prior to the 12th class day of a regular semester or the 4th class day of a summer session. A student who audits a course may not change registration during the semester to take the course for credit.
