Tevis managed a hectic schedule. Not only was she a wife and a mother to seven children, but she also taught classes and oversaw a school that grew every year. As this list shows, 65 young women boarded at the school in 1838. The Tevises used their "time off" during the summers between 10-month terms to build onto the campus to accommodate an expanding student body.
Tevis developed a rigorous curriculum that included philosophy, theology, algebra, geology, botany, and astronomy. Later the curriculum included trigonometry, chemistry, physiology, geology, and psychology. Tevis also looked after and tracked the students' everyday needs.
