Big 8 Conference (Missouri)

The Big Eight Conference is an athletic conference comprising medium-size high schools located in the Ozarks of southwest Missouri. The conference members are based around the Joplin and Springfield areas and are located in the counties of Barry, Barton, Lawrence, McDonald, Newton, and Vernon.

1928
The conference was established as the Southwest Activities Association but was known as the Big 10. Founding members were: Aurora, Carthage, Joplin, Lamar, Monett, Mt. Vernon, Neosho, Nevada, Springfield and Webb City.

1953
The Big 10 changed to the Big 9 when Springfield and Joplin left the conference and Cassville was added.

1963
The Big 10 was re-established when Carl Junction was added.

1976
The Big 10 added McDonald County, East Newton, and Seneca to form the Big 13 Conference.

1979
Webb City leaves the conference for two years thus causing the renaming to the Big 12 Conference.

1981
Webb City is reinstated into the conference. The conference is renamed the Big 13 Conference with schools divided into two divisions.

1982
Joplin (Memorial) lured Neosho, Webb City, Carthage, McDonald County, and Nevada to form the Big 6 Conference. The remaining schools formed the Big 8 Conference (Aurora, Carl Junction, Cassville, East Newton, Lamar, Monett, Mt. Vernon, and Seneca).

In 1985, Joplin Memorial merges with Joplin Parkwood to form Joplin High School and thus, the Big 6 Conference is renamed the Southwest Conference. Teams are: Joplin, Carthage, McDonald County, Neosho, Nevada, and Webb City.
