For more than 30 years, Wellesley has offered a cross-registration program with MIT. Students can participate in research at MIT through the Undergraduate Research Opportunities Program (UROP). In recent years, cross-registration opportunities have expanded to include nearby Babson College, Brandeis University, and Olin College of Engineering. To facilitate cross-registration, the Wellesley College Senate bus connects Wellesley to the Harvard University and MIT campuses in Cambridge, Massachusetts; additionally the college also operates a shuttle to the Babson College and Olin College campuses. It is also a member of a number of exchange programs with other small colleges, including opportunities for students to study a year at Amherst, Connecticut College, Dartmouth, Mount Holyoke, Smith, Trinity, Vassar, Wesleyan, and Wheaton.
