The Hoosier Heartland Conference is an IHSAA-Sanctioned Athletic Conference in
North Central Indiana. It comprises mainly single A (less than 400 students) schools. Carroll (Flora) and
Clinton Central are currently 2A. Lafayette Central Catholic joined the Hoosier Athletic Conference after the
2010-11 school year, and was replaced by Sheridan, who joined after the 2011-
12 season. With the major conference realignment in Indiana in 2015, the conference picked
up four schools from neighboring conferences that were folding, as well as a football-only
member to balance the new football divisions.
