The Duneland Athletic Conference (DAC) is a high school athletic conference in Indiana serving eight members of the Indiana High School Athletic Association. Member schools are located in the counties of Lake, LaPorte, and Porter along Indiana's Lake Michigan shore. Each school is classified based on enrollment as 6A or 5A for football and 4A for basketball, the classes for the largest schools in Indiana. The Duneland Conference is also quite known for its gymnastics programs which have won a combined total of 27 state championship and state runner-up titles.
1970: Chesterton, Portage, Valparaiso, and Hobart High School began competition as the Duneland Athletic Conference. Chesterton & Portage had been members of the Calumet Conference; Hobart & Valparaiso had been independents.1972: Michigan City Rogers joins the DAC.1975: Merrillville joins the conference, leaving the Lake Suburban Conference.1976: LaPorte joins following its departure from the Northern Indiana Conference.1993: Crown Point joins the DAC following the disbandment of the Lake Suburban Conference.1995: Michigan City Rogers is merged with Michigan City Elston, who was a member of the Northern Indiana Conference, to form Michigan City High School.2003: Hobart, the only non-5A football school, leaves to join the Lake Athletic Conference. Lake Central joins in place of Hobart following being independent since the disbandment of the Lake Suburban Conference in 1993. Hobart is currently with the Northwest Crossroads Conference after the 2007 disbandment of the Lake Athletic Conference.2013: Football has a new class, 6A, meaning that the teams to move from 5A to 6A are Portage, Lake Central, Chesterton, Crown Point, Valparaiso, & Merrillville. The only teams to remain in the 5A class were LaPorte and Michigan City. LaPorte was moved up to 6A in 2015.In 2002, five schools - East Chicago Central High School, Elkhart Central High School, Lake Central High School, Mishawaka High School, & Penn High School - submitted proposals to join the DAC when expansion talks began following Hobart's announcement it would leave to join the Lake Athletic Conference. Lake Central, Mishawaka and Penn were invited to join the DAC. Mishawaka, shortly followed by Penn, opted to not join the conference. These two schools cited wanting Elkhart Central and East Chicago Central to have been invited to join as well. This coupled with the extensive travel times to Lake County schools and the time zone difference led to their decision to remain in the Northern Indiana Conference.
