The Division of University Extension, established in 1939-40, became Associated Schools. Each of the associated schools had its own dean and faculty, with the exception of Jackson College, which always shared the same faculty as the School of Liberal Arts. In 1939, following the retirement of the long-time dean of the School of Liberal Arts, the separate posts of dean of the Faculty of Arts and Sciences and dean of admissions were created. The Division of University Extension was renamed the Division of Special Studies in 1949. Except for the 1962-1965 period, the School of Religion (formally renamed the Crane Theological School in 1955) was one of the Associated Schools of the Faculty of Arts and Sciences from 1903 until the school's closing in 1967. When Tufts College formally became Tufts University in 1952, the undergraduate divisions were renamed "colleges" and the graduate and professional divisions were renamed "schools."
