The members of the MIAA remained the same from 1961 until 1997 when Defiance College of Ohio and Saint Mary's College of Indiana were invited to join, the first time colleges from outside Michigan were admitted to the conference. Adrian, Albion, Alma, Calvin, Hope, Kalamazoo, Olivet and Saint Mary's have not been members of any other conference. In 2002, the league accepted Wisconsin Lutheran College as an associate member for the purpose of competing only in football. Wisconsin Lutheran College left the MIAA for another conference in 2007. The newest member of the MIAA was accepted in the 2004–05 season, Tri-State University. Tri-State University changed their name to Trine University in 2008.
