The DuPage Valley Conference (DVC) is an organization of six high schools in northeastern Illinois, representing seven communities in Chicago's suburbs. These high schools are all members of the Illinois High School Association. The Conference, organized in 1975, exists primarily for inter-school athletic competition in 21 sports. There are also four non-athletic competitions in which DVC schools participate: Chess, Math competitions, Scholastic Bowl and Speech. Four of the six current conference member schools are within DuPage County, Illinois. One school, Neuqua Valley High School, is located just to the south of Du Page in Will County, Illinois while DeKalb High School is located west of the other schools in DeKalb County, Illinois. The conference derives its name from the DuPage River, which flows through two of the seven represented communities (although students from towns on the DuPage River do attend more of the member schools, due to attendance boundaries). History The DuPage Valley Conference was formed prior to the 1975–76 school year. Its charter members were Glenbard North High School, Glenbard South High School, Naperville Central High School, Naperville North High School, West Chicago Community High School, Wheaton Central High School, Wheaton North High School, and Wheaton Warrenville High School. While the conference has typically kept a constant membership of at least six high schools, the actual membership of the Conference has changed since its founding. The conference experienced the first membership change in 1983, when Glenbard East High School left the Des Plaines Valley League and joined the DVC, replacing Wheaton-Warrenville High School, which was closed due to low attendance. The next change came in 1992, when Wheaton Central High School and Wheaton-Warrenville Middle School changed buildings. The high school (now in the former Wheaton-Warrenville high school building) became known as Wheaton-Warrenville South High School in order to distinguish it from the closed Wheaton-Warrenville; the middle school (in the old Wheaton Central building from 1992-2009) became Hubble Middle School. After the 1996 school year, Glenbard South High School left the DuPage Valley Conference, citing an inability to be competitive with the larger member schools in the league (despite winning a share of the conference title in softball in their final year in the conference). The DuPage Valley Conference operated for one year with only seven schools before admitting former Upstate Eight Conference member West Aurora High School in Aurora, Illinois, the first DVC school outside DuPage County.
