The conference started in 2000, as the West division of the
Olympic Conference (Brownsburg, Hamilton Southeastern, Harrison, McCutcheon, and Noblesville) joined with two schools from the folding
Rangeline Conference (Westfield and Zionsville) and one from the
Mid-State Conference (Avon). Lafayette Jeff joined in 2004 from the
North Central Conference, and Fishers joined upon reopening in 2006. In December 2012, Indianapolis-area schools voted to sever ties with Tippecanoe County schools following the 2013–14 school year due to transportation costs, travel time constraints, differences in school size, and competitive balance. The Lafayette area schools joined the
North Central Conference. In March 2017, the conference schools met to decide on letting an eighth member into the conference,
Franklin Central. On March 15, 2017, the HCC admitted Franklin Central Flashes into the conference, effective for the 2018–2019 school year. ==Member schools==
