Oregon School Activities Association

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 also either three or four classifications (dependent 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 2018–22, a 1A school has fewer than 89 students, 2A between 90 and 205 students, 3A between 206 and 349 students, 4A between 350 and 664 students, 5A between 665 and 1259 students, and the largest schools, 6A, have 1260 or more students. However, some schools choose to "play up" in a larger classification than they would normally be assigned.
