If a student requests to audit a course they must enroll in the course with the grade option audit and no grades are to be assigned to the student.
Per Senate Rule 5.1.4.
Students who register for an audit do so for reasons other than fulfilling explicit requirements. They must come to individual agreements with the instructor as to what responsibilities they will be expected to perform. Normally, students who audit would be expected to do the readings and attend class; they may be required to enter more fully into the class work. In any case, they will receive no credit hours or grades. Any change from audit to credit or credit to audit by a student regularly enrolled in a college must be accomplished within three (3) weeks from the beginning of classes in the fall or spring semester (or a proportionate amount of time in the summer session or other courses of less than a full semester's duration). No credit can be conferred for a class audited nor is a student permitted to take an examination for credit, except for the special examinations described in 5.2.1.2.
Per the clarification on the rule.
The rule states “No instructor is authorized to admit anyone as an auditor to any of his/her classes unless the auditor has registered as such”, This means no person can audit a class without enrolling as an audit. The descriptors “audit” and auditor” means that a person is present to obtain educational edification.
