The 2010 PACE NSC was held on June 5-6th at George Mason University in Fairfax, Virginia. It was the first NSC where a 20/20 tossup-bonus format was used, abandoning the old PACE format that had been used since 1998. The tournament was won by State College, with Maggie Walker taking second. The top scorer was Matt Jackson from Georgetown Day School.
The 2010 NSC was the first high school national championship to use "superplayoff" crossover games, such that the top four teams in each of the two playoff brackets had to play four more games across brackets to determine a complete order of finish among the top 8 teams at the tournament.
