As the conference moved through the 1970s the number of teams remained the same, however, after the 1980 school year, Homer, Newman and Oakland would leave for the newly formed East Okaw Conference.[6] However, Arcola and Lovington would join that same year.[7]
The conference would include only six schools for the remainder of the 1980s with the next change occurring in 1994 as Atwood-Hammond and Bement would join forces as the South Piatt[8] Coop during the football season, however, they would compete as individual schools for all other sports. Additionally that same year, Tuscola would join the league from the now defunct Meridian Conference.[9] This, however, gave the league an odd number for all other sports beyond football.
Two years later, in 1996, the conference expanded with the addition of BroadlandsHeritage, HumeShiloh,[10] Illiopolis[11]Niantic-Harristown[12] and the return of Oakland High School.[13] This would put the league at 12 schools for all sports except football where there were 11 teams. The number of football teams were reduced for the 1997 season when Heritage and Shiloh began a football coop known as East Central.[14] The league would stay nearly the same as the 1990s came to a close.
As the 2000s began, the league remained stable with very few changes. Bethany[15] and Findlay High Schools[16] consolidated into Okaw Valley[17] and joined the league in 2001, the same year the Meridian Conference would cease to exist. In 2004, the high schools from Niantic-Harristown and Illiopolis consolidated, becoming Sangamon Valley High School.[18] This again reduced the number of schools competing in the conference. However, the conference was not done growing and by 2006 the list of schools included 12 teams: Arcola, Arthur, Atwood-Hammond, Bement, Cerro Gordo, Heritage, Hume Shiloh, Lovington, Okaw Valley, Sangamon Valley, Tuscola, and Villa Grove.[19] However, this would be the final year for Tuscola, they would leave for the Okaw Valley Conference at the end of the 2006–07 school year. In 2009, Martinsville,[20] joined the league, increasing the number of schools to 13.[19][21] The conference would remain status quo until 2014 where an expansion would take place as nine schools would leave the Okaw Valley Conference.[22]
Argenta-Oreana, Decatur LSA, Hutsonville/Palestine (coop), Oblong, and ToledoCumberland would join in 2014.[23] This increase in schools created a two division football conference prior to the 2016 season. Those divisions were the Northwest and Southeast. The Northeast included: Arcola, Argenta-Oreana, Arthur-Lovington-Atwood-Hammond, Cerro Gordo-Bement, Decatur LSA, and Sangamon Valley. The Southeast included: Cumberland, Martinsville, Oblong, Palestine-Hutsonville, Tri-County, and Villa Grove.[24] In 2018, another new member would join the LOVC, Blue Ridge High School.[25]
Unfortunately, even before Blue Ridge joined the league, an uprising had begun based on the distance required to travel between schools as well as maintaining a closed football conference. Because of situation, in December 2017, 15 of the conference schools announced their intention to leave the LOVC.[26][27] These schools were moving to a new conference, the Lincoln Prairie. The only schools not moving to the new league were Martinsville, Hutsonville, Palestine and Oblong.
The most recent school to join the conference is BridgeportRed Hill High School.[28] As of 2023, the conference maintains five high schools: Bridgeport Red Hill, Hutsonville, Oblong, Palestine, and Martinsville.[29] None of the current schools are charter members.
