The Oregon School Activities Association (OSAA) oversees competition among its members. Every four years the OSAA does a reclassification process that evaluates member schools and organizes them into classifications based primarily on school enrollment. Each classification then has a number of leagues that are created based primarily on proximity. In the Hillsboro School District we have three schools that compete at the state's highest level (6A) in the Pacific Conference: Century, Glencoe and Liberty. Hillsboro High School is a member of the 5A Northwest Athletic Conference. The OSAA has completed its classification for the 2022-2026 timeline and will next update the classifications in the 2027 school year.
