USO has a board management and, in this school year, around 100 teachers, 600 students and 4 staff (the only ones that are paid in the institution). The USO teachears are volunteers (almost retired, too), but they can also be students. Each year, each teacher submits the programs and methodologies that intends to teach. Each student chooses the preferred disciplines to sign up, with a limit for theory and pratica. There are no specific rules regarding the disciplines that each one chooses to enroll, although they have a limited number of years for attendance. There isn´t any final evaluation although the indiators used by USO develop a rank of good and not so good disciplines.
