Starting Spring 2026, Dornsife Advising will move to a newly structured Cluster Advising model for undergraduate academic advising, reflected in Advise USC. Beginning this term, academic advisors will work in case teams, allowing you to meet with any advisor within your Cluster Focus area. Instructions to submit a support case can be found at Advisor Connect Tab.
