When the degree requirements of a graduate program undergo changes, a student already enrolled in the program is by default subject to the old degree requirements. In the event that a certain required course is no longer available due to program changes, a student may petition to make reasonable course substitutions. See Credit Policies > Course Applicability.
If a currently enrolled student elects to fulfill new degree requirements instead of the old degree requirements, the student needs to obtain approval from the graduate chair, who will in turn notify the Office of Graduate Student Services via a memo. Until such a memo has been received by the Office of Graduate Student Services, the student is subject to the old degree requirements.
