Fox Valley Conference

The conference consists of 10 teams total.^[1] All enrollments^[2] and classifications^[3] are from the Illinois High School Association website. The schools who are part of the conference are Burlington Central, Hampshire High School, Huntley High School, Dundee Crown High School, Jacobs High School, Mchenry County High School, Crystal Lake South, Crystal Lake Central, Cary Grove, and Prairie Ridge High School

• Dundee Community High School and Irving Crown High School, both charter members of the FVC, consolidated to become Dundee-Crown at the start of the 1983–84 school year.
• Lake Zurich joined the conference in 1991–92.
• Grayslake (now known as Grayslake Central) joined in 1997–98. Prairie Ridge opened this year and joined the conference as well.
• Huntley joined in 2003–04. (This led to a scheduling issue for the football season. With 11 schools in the conference, it was impossible to have each school play all 10 other conference opponents because the football regular season is only 9 games.)
• Lake Zurich left to join the North Suburban Conference after the 2004–05 school year.
• Johnsburg and Grayslake North joined in 2006–07. The 12 schools were split into two divisions: the smaller schools (Crystal Lake Central, Grayslake Central, Grayslake North, Huntley, Johnsburg, Prairie Ridge) in the Fox Division, and the larger schools (Cary-Grove, Crystal Lake South, Dundee-Crown, Jacobs, McHenry, Woodstock) in the Valley Division.
• Woodstock North joined in 2009–10, being placed in the Fox Division. With Woodstock's enrollment split in half due to Woodstock North opening, it moved down to the Fox Division, and Huntley moved up to the Valley Division.
• Hampshire joined in 2011–12. They joined the Fox Division, and Prairie Ridge moved into the Valley Division.^[4]
• Johnsburg left to join the Big Northern Conference in 2014–15. Prairie Ridge moved back into the Fox Division.
• Woodstock and Woodstock North left in 2016–17 to become charter members of the Kishwaukee River Conference. Grayslake North and Grayslake Central also left this same year to become charter members of the Northern Lake County Conference. With only 9 remaining schools, the FVC eliminated its division format.
• Central joined in 2019–20.^[5]
