During the vacations that happen between semesters and at Thanksgiving break, students must make arrangements either to go home or to stay off campus. During the fall and spring semester long weekends, students may remain on campus.
The school year is broken into two semesters, with long weekends in October and April for family days, Thanksgiving (when all students leave campus), and two-and-a-half week long breaks in December and March. The NMH calendar can help you plan.
