OSAA Centennial

100 Years of Leadership and Sportsmanship

The 2018-2019 school year marks the 100th year of the OSAA. In 1918, a corps of high school administrators met to establish rules on age, amateurism, attendance and scholarship. The resulting action was the formation of the Oregon State High School Athletic Association. In 1947, the name was changed to the Oregon School Activities Association to reflect the widening scope of activities, which included more than sports.
