Beginning Spring 2026, Dornsife Advising uses a Cluster Advising model for undergraduate academic advising, as reflected in Advise USC. Under this model, academic advisors work in case teams, allowing you to meet with any advisor within your Cluster Focus area. Instructions for submitting a support case are available through the Advisor Connect Tab.
