All IECO majors must complete a senior seminar. The IECO-401 Senior Seminar (thesis course) is offered only in the spring semester. IECO-401 is required for students pursuing honors and is optional (but recommended) for others. Students who opt not to take IECO-401 must take an approved 400-level ECON course in its place. Students who wish to graduate early may take IECO-401 in the spring semester of junior year.
