Tri-Eastern Conference

The current nine teams are located in the counties of Henry, Randolph, Union, and Wayne.

All five are current members of the conference, albeit two have different names through consolidation (Cambridge City became Lincoln in 1965, and Liberty became Short in 1965, then Union County in 1973).

Brookville (now Franklin County) and Hagerstown joined in 1966 to bring the membership to 7, however Knightstown would leave in 1968 (with Brookville following suit in 1973).

The conference would grow to 7 members in the 1970s, adding Winchester (1972) and Northeastern (1974).

Knightstown would rejoin in 2017 with a phased program, with some sports joining in 2018.
