This has eventually expanded to also include National Association of Intercollegiate Athletics schools, because the NAIA at that time did not recognize lacrosse as a sanctioned sport.
Over time, it was decided that the MDIA had become too complicated for US Lacrosse to administer and on August 24, 2006, the MDIA Board of Directors announced formation of a new organization called the Men's Collegiate Lacrosse Association (MCLA) as its replacement.
It was agreed that the MDIA would cease to exist, that the new MCLA would run its own national tournament and control its own budget, but still sit on US Lacrosse boards and committees.
The WDIA in January 2011 was also reorganized and renamed the Women's Collegiate Lacrosse Associates (WCLA).
