Wilsonville, OR 97070 The Oregon School Activities Association (OSAA) is a non-profit, board-governed organization that regulates high school athletics and competitive activities via athletic conferences in the U.S. state of Oregon, providing equitable competition among its members, both public and private. The OSAA is based in Wilsonville.

History

Originally created in 1918 as the "Oregon State High School Athletic Association", the name changed to the "Oregon School Activities Association", or OSAA, in 1947.

Currently, the OSAA sponsors seventy-four state championships in nineteen interscholastic activities including athletics, music, and forensics and is a member of the National Federation of State High School Associations.

Starting in the 2006–07 school year, the organization's four school classifications (1A, 2A, 3A, 4A) were divided into six classifications (6A, 5A, 4A, 3A, 2A, 1A). This caused some controversy as some school districts complained about the new classifications and sought legal action. OSAA voted to keep a six classification system in 2017.

Classifications and leagues

The OSAA divides schools up into classifications and leagues (or conferences).

There are six classifications, with the smallest schools in class 1A and the largest schools in class 6A. Within each classification, there are between five and eight leagues and conferences. Each league or conference has between four and 15 schools. Prior to 2006, there were four classifications (4A, 3A, 2A, 1A), prior to 1990, there were four classifications (AAA, AA, A, B), and prior to 1970, there were either three or four classifications (depending on the sport), but they were designated as A, A-2, B, B-8 for football, A-1, A-2 and B in basketball and A, A-2, & B for baseball.

According to OSAA's classification system for 2026-30, a 1A school has fewer than 65 students, 2A between 66 and 140 students, 3A between 141 and 280 students, 4A between 281 and 580 students, 5A between 581 and 1025 students, and the largest schools, 6A, have 1026 or more students.

As of the 2026-30 season, OSAA's classifications comprise the following Currently working on..
