East Central Conference

The ECC was founded in 1970 with Berlin, Hortonville, New London, Omro, Ripon, Waupaca, Weyauwega and Winneconne as the original members.

In 1999, Hortonville, Little Chute and Waupaca joined the newly formed Valley 8 Conference, while Waupun became a full-time member.

Members included: Berlin, Campbellsport, Kewaskum, Kettle Moraine Lutheran, Plymouth, Ripon, Waupun and Winneconne.

In 2021 It was presented by Berlin and Ripon to request moving the two schools to the nearby South Central Conference due to declining enrollment and finishing near the bottom in most sports.

Both request were denied by the WIAA Task force due to no solution to move Plymouth, Kewaskum, Kettle Moraine Lutheran and Waupun.
