History
The league began with the 1973-74 sports season.Britton and Deerfield combined all sports starting with the 2009-10 sports season, although they already were combining some sports for several years. Their districts combined on July 1, 2011 into the Britton-Deerfield School District.
In 2018, Whitmore Lake elected to leave the conference in favor of joining the Michigan Independent Athletic Conference for the 2019-2020 season. However, Erie Mason has been invited to and will join the TCC in its place for the 2020-21 athletic year.
In 2019, Clinton announced it would depart the conference and return to Lenawee County Athletic Association beginning in the 2020-21 athletic year. To take their place, Pittsford will join the league in football, bowling, and wrestling only. This move comes as a result of every other member of the Southern Central Athletic Association moving to 8-man football. Pittsford will remain in the SCAA for all other sports.
Since Pittsford is in Hillsdale County, the TCC will once again comprise three counties and the name "Tri-County Conference" will be accurate.
