Originally, the institute was organized as a four-year academy as well as a two-year college. There was only one other high school in the city of Peoria at the time. By 1899 the institute had expanded to accommodate nearly 500 pupils, and study fields included biology, chemistry, food work, sewing, English, German, French, Latin, Greek, history, manual arts, drawing, mathematics, and physics. By 1920 the institute dropped the academy orientation and adopted a four-year collegial program. Enrollment continued to grow over the coming decades and the name "Bradley University" was adopted in 1946.
