The top eight teams in the WCHA, according to their final conference standings, were eligible for the tournament and were seeded No. 1 through No. 8. In the first round the first and eighth seeds, the second and seventh seeds, the third and sixth seeds and the fourth and fifth seeds were matched in two-game series where the school that scored the higher number of goals was declared the winner. After the first round the remaining teams were reseeded No. 1 through No. 4 according to their final conference standings and advanced to the second round. In the second round the first and fourth seeds and the second and third seeds competed in an additional two-game, total goal series with the winners of each being declared as co-conference champions.
