Format
The competition consisted of 79 teams: 40 championship teams and 39 open teams. The divisions were further divided into a men's and women's division: 24 men's and 16 women's teams in the championship division and 20 women's and 19 men's teams in the open division. The divisions were then further divided into groups: eight groups of three teams in the men's championship, four teams of four teams in the women's championship and five groups of four teams each in the men's and women's open. All four divisions engaged in a round-robin tournament that determined teams able to advance to a knockout stage. Each team played every other team in their group once in pool play which consisted of two 40-minute halves separated by a seven-minute halftime. Pool play utilized the three points for a win system and after pool play, the two highest ranked teams from each group in the championship divisions advanced to their respective knockout stage, with the third placed team in the men's championship advancing to a consolation bracket while the third and fourth placed teams in the women's championship being eliminated. In the open divisions, each pool winner automatically advanced in addition to three additional wild-card teams. Positions 1 and 8 were given to first place teams in groups that didn't have a wild-card team in order of tie-breaking procedures, positions 2, 6, and 7 were given to wild-card teams in order of tie-breaking procedures, and positions 5, 3, and 4 were given to the pool winners from the pools of the 2, 6, and 7 positioned wild-card teams, respectively. Knockout stage games also consisted of two 40-minute halves. The round of 16 and quarterfinals were separated by a seven-minute halftime while the semifinals and finals had a ten-minute halftime. Knockout stage games needed to declare a winner, therefore if a game was tied at the end of regulation, two five-minute overtime periods would be played to completion. If still tied after overtime, kicks from the mark would determine the winner.

Qualification and selections
Each of the six regions received three automatic bids for the men's championship division and two automatic bids for the women's championship that they awarded to its members. The final bids for each division were considered "at-large", and were given out by NIRSA to teams, typically based on their regional tournament results and RPI.

The remaining teams participated in the open division, chosen on a first-come first-serve basis via online registration beginning on September 12, 2006 with a max of 16 teams per gender division.
