The 2015 NAQT HSNCT was held at the Hyatt Regency O'Hare on May 30-31, 2015. As in the 2014 HSNCT, 272 teams attended the tournament.
After a schedule of 10 power-matched preliminary games and several rounds of double elimination, LASA A emerged as the only undefeated team going into lunch on Sunday, having won out of the winner's bracket to secure a spot in the finals. Nonetheless, further gameplay secured Arcadia A and DCC A the second and third spots in a three-team, two-game finals series, in which Arcadia A emerged victorious, defeating DCC A first 580-185 and then triumphing over LASA A, 410-285.
Arcadia is the first school from Southern California to win the HSNCT and the second school from California after 2012 Bellarmine. With their victory, Arcadia prevented LASA from winning the HSNCT three years in a row, a feat only achieved by Thomas Jefferson (VA) from 2003 to 2005.
The top individual scorer was Sam Blizzard of Northmont High School, followed by Kai Smith of Knoxville Scholars.
