## Format

The tournament featured three rounds of play. The two odd-number ranked teams from one region were placed into a bracket with the two even-number ranked teams of the other region. The teams were then seeded according to their ranking. In the Quarterfinals the first and fourth seeds and the second and third seeds played two-game aggregate series to determine which school advanced to the Semifinals. Beginning with the Semifinals all games were played at the 1980 Olympic Arena and all series became Single-game eliminations. The winning teams in the semifinals advanced to the National Championship Game with the losers playing in a Third Place game.
