Olympic Conference (Illinois)

The six charter members were Astoria, Bushnell, Cuba, Lewistown, Spoon River Valley, and Table Grove VIT.

After the 1981–1982 season Abingdon and Knoxville left to help form the Prairieland Conference, bringing the total to 6 schools.

[6] In the fall of 1992 Farmington joined and Knoxville rejoined the Olympic, again giving the league an 8 team alignment.

[5] Knoxville left after the 2008–2009 academic year,[8] and Farmington departed after the 2009–2010 season,[9] both to rejoin the Prairieland conference.

Due to the geographic range of the newly aligned West Central Conference, it was split into north and south divisions for most activities, with the five remaining Olympic Conference schools and Illini West High School (Carthage) comprising the north division.

[10] Mercer County High School considered joining the West Central Conference beginning in 2011.

The present day Olympic Conference won 23 state championships in IHSA sponsored athletics and activities.
