While instruction in the liberal arts and sciences dates to the founding of Tufts College in 1852, the formal organization of the school came almost fifty years later. In 1903, the Trustees of Tufts College adopted a "new plan" of organization that divided the college into several schools: Liberal Arts (formerly Letters), Engineering, Divinity (or Religion), Graduate Arts and Sciences, as well as the schools of medicine and dental medicine. The first four, all located on the Medford/Somerville campus, were grouped together as the "Department of Arts and Sciences" (later the Faculty of Arts and Sciences). This organization required any policy that affected the schools in the Department (the "Associated Schools") to be considered first by the constituent faculty and then by parent body. (This pattern of organization continues to the present day). The medical and dental school, located in Boston, remained outside this overlapping pattern of organization, as did the Fletcher School (established in 1933).
