The curriculum centerpiece is a "Reading Culture" that helps boys with reading problems, while it challenges good readers to become better. The required athletic program offers every boy an opportunity to participate and gain physical skills while learning teamwork. The school’s electives emphasize the development of boys’ creative talents in the fine arts, while refining their social skills.

These resident advisors supervise and teach group interaction skills, while training cadets to keep their rooms and schedules in good order.
