The growing enrollment necessitated a reorganization of the school. Under the direction of Waters, the school day was divided into eight periods lasting forty-five minutes: four sessions were held in the morning and four in the afternoon. In addition to reorganizing the schedule, he divided the courses into seven different departments: Belles-letters and history, mathematics, natural sciences, moral, mental, and political science, ancient languages, modern languages and music. Each of the seven instructors was assigned to a distinct department and received the title of "professor".
