Sports

Each year a conference champion is determined in each division for volleyball, boys and girls basketball, baseball, and softball by each division member playing round-robin home and away. The team with the best win–loss record is the champion.
For boys and girls golf and boys soccer one champion is determined by round–robin play, with each school in the conference playing each other once. The team with the best win–loss record is the champion.
Cross country and track & field for boys and girls each have one champion determined by the winner of each sport's conference meet. The scholastic bowl champion is the winner of the conference tournament.
Like golf and soccer, the conference football championship is determined based on round–robin play. However, only seven teams field football teams. As noted above, Carlyle will begin 8-man play in 2020 moving the conference to 6 schools for the short-term.
There is no cross-over for conference play due to the size discrepancy between schools in the Mississippi Division and schools in the Kaskaskia Division.
