The Small Boarding Schools Association was founded in 1987 by a group who felt that small boarding schools needed their own gathering to address those issues unique to their type of school.

The Oregon Federation of Independent Schools (OFIS) is an organization representing private preschool and K-12 schools in Oregon. Governed by a board of directors reflecting the diversity of Oregon’s private schools, OFIS works to ensure that Oregon private schools are able to operate with a minimum of government influence or control so that parents can choose from a wide range of educational options for their children. OFIS conducts programs and meetings throughout the year and sends email news updates to keep its members informed of developments and news affecting private schools.

The Oregon School Activities Association, OSAA, is a non-profit, board-governed organization comprised of its member schools, both private and public. The OSAA is dedicated to ensuring equitable competition for Oregon high school students through OSAA-sponsored events. The foundation for that goal lies in a belief that no school, team or individual should be treated as any more or less than another.

OSAA standardized rules of eligibility and competition, and put in place a standard of education regarding participation in interscholastic activities. Administered equally and fairly, OSAA policies strive to allow no one school to outweigh its brethren.
