Dartmouth College students may attend the Williams-Mystic Maritime Studies Program under the Twelve College Exchange.

All of the Twelve College exchange colleges except Dartmouth operate on a semester schedule. A Dartmouth student wishing to participate for the first semester can adjust the semester to the Dartmouth fall term, but the second semester takes part of both winter and spring terms at Dartmouth. Ordinarily students earn four credits in a semester. Each of the colleges differs in its academic offerings, strengths of various departments and the geographical and social environments.

Applications for the ensuing year, either for the first or second semester, must be submitted by February 1; sometimes it is possible to negotiate individual arrangements subsequently. The application process stresses the importance of the particular exchange program and courses in a student's program. Applicants must have a minimum cumulative grade-point average of 3.0

Students pay the tuition, room and board for each semester at one of the twelve colleges directly to the host college.

Upon completion of the exchange, the exchange coordinator at the host institution will forward the transcript to the Office of the Registrar, Dartmouth College. Future transcripts of exchange program grades must be obtained by the student from the exchange institution.
