The Upperclass Deans Office, a department within the Dean of the College division, provides support for students in the sophomore, junior and senior classes as well as for other enrolled students. The office's main mission is to support students in their engagement with the curriculum and in their overall experience at Dartmouth. Although each of the class deans has specific areas of academic and counseling expertise, they are generalists in the sense that they support the mission of the office

A dean is assigned to each class, and follows the class from its sophomore through its senior year. Students can schedule appointments with any of the deans even if not assigned to their class year.
