Newton adopted the graduate education model and three-year curriculum pioneered by Andover Theological Seminary, with which it shared a theological tradition of evangelistic zeal. Students from the two institutions were at the forefront of the modern missionary movement.
Newton shared its campus with Andover from 1931 to 1965, when the schools formally merged to form Andover Newton Theological School. By virtue of Andover's prior affiliation with Harvard University, students of Andover Newton are allowed to take classes in any of Harvard's ten graduate schools.
