reunited West Aurora with former Upstate Eight charter members Naperville Central, and Wheaton-Warrenville South who were then known as Naperville Community, and Wheaton Community in 1963. Effective at the start of the 2013-14 conference season, West Chicago Community High School left the DuPage Valley Conference and joined the Upstate Eight Conference (Valley Division). At the same time Lake Park High School took the vacant space after leaving the Upstate Eight Conference Valley Division. Following suit with West Chicago Community High School, Glenbard East High School and West Aurora High School expressed interest in joining the Upstate Eight Conference. The two schools voted unanimously to accept the invitation to the Upstate Eight Conference starting in the 2014–2015 season. This effectively left the DVC as a 6 member high school conference. Glenbard North High School declined an invite from the Upstate Eight Conference to join. Prior to the 2015–2016 school year, Metea Valley High School, Neuqua Valley High School, and Waubonsie Valley High School, all formerly of the Upstate Eight Conference Valley Division, accepted an invitation to join the DuPage Valley Conference, bringing the membership to 9 schools. In late 2016, four members of the DVC, Glenbard North High School, Lake Park High School, Wheaton North High School, and Wheaton Warrenville South High School announced that they would be leaving the conference effective at the end of the 2017–18 school year to form a new athletic conference with current Upstate Eight (River Division) members Batavia High School, Geneva High School, St. Charles East High School, and St. Charles North High School. The conference is now known as the DuKane Conference. The remaining DVC members Metea Valley, Naperville Central, Naperville North, Neuqua Valley, and Waubonsie Valley continued athletic competition in the DVC despite scheduling concerns, particularly for football. DeKalb High School accepted an invitation to join the DVC for the 2019-2020 season following the break-up of the Northern Illinois Big 12 Conference.
