The Northwest Conference is an OHSAA athletic league located in northwest Ohio and includes schools in Allen, Hardin, Paulding, Putnam, and Van Wert counties. The NWC originally formed in 1947. The Northwest Conference currently awards championships in 10 Varsity sports: baseball, basketball, cross country, football, golf (boys), softball, soccer (girls), track, volleyball, and wrestling.
The Northwest Conference begins its inaugural season of competition in the fall of 1947 with the eight charter members: Columbus Grove, Delphos Jefferson, Elida, Forest, Lafayette-Jackson, Pandora-Gilboa, Lima Shawnee, and Spencerville.
2000: Crestview, having restarted their football program as an independent in 1999, officially starts play as a conference member again.
2002: Upper Scioto Valley, facing possible removal because of their failure to reliably field a football team during the 2001 season, opts to leave the conference at the conclusion of the 2001-2002 school year. They join the Northwest Central Conference beginning in 2003-2004.
2004: Lima Perry finishes its final year as a conference member after announcing their move to join USV in the NWCC in 2003.
2006: Lima Central Catholic begins play as a conference member after several years of petitioning.
2011: On December 1, the Lima Central Catholic administration announced that due to the results of being voted out of the NWC, they would leave the conference at the conclusion of 2012-2013. The move is made in part due to concerns from other conference members over fairness and competitive balance. A scheduling agreement agreed to before the announcement keeps LCC on NWC members' athletic schedules through the 2014-2015 school year unless there is a mutual decision between a conference member and LCC to break the agreement. As of September, 2013, Lima Central Catholic will remain an independent after unsuccessful negotiations with many other area conferences to become a member.
2012: Ada and Bluffton are asked to apply for membership in the expanding (and neighboring) Blanchard Valley Conference in March. Bluffton declines the BVC's invitation while Ada is rumored to express interest before, ultimately, ending negotiations and remaining a member of the NWC. The BVC invites North Baltimore and Hopewell-Loudon who both accept.
