Beginning in 1937, the University of Chicago's experimental, interdisciplinary College program admitted students beginning in the sophomore year of high school.[12] Because there were few formal requirements, early entrants in this program were largely self-selecting, and came mostly from nearby schools such as the University High School.[13] Early entrants were subject to five additional comprehensive examinations, but otherwise went through the same academic program as high school graduates.[14] Although the University of Chicago eventually abandoned this program, it was adopted by tiny Shimer College in 1950,[15] and continues there in a modified form to the present day.[7]
