Northern Indiana Athletic Conference

Like the Southern Indiana Athletic Conference, the NIAC was also a superconference that spanned several counties, and a lot of driving miles, for a period between 1940 and 1965. Throughout the 1970s the membership dwindled as many schools left to form new conferences. From 1995 to 2015 the two conferences share the same setup with 7 or 8 schools in one county, 8 in this case from St. Joseph County and 1 from an adjacent county, Elkhart in this case. This will change in 2015, as four schools from the folding Northern State Conference will join, making a 13 school conference.[1] This will also expand the conference footprint into two counties formerly represented in the NIAC: LaPorte (last represented in 1995) and Marshall (last represented in 1930). 2020 will bring more change, as Elkhart Central merges with former member Elkhart Memorial to form Elkhart high school, and Mishawaka leaves for the Northern Lakes Conference, taking Memorial's spot in that league.[2]
