Southern California maintains one of the most active quizbowl circuits in the nation. On average, there is one tournament every month, spread all around the region, from La Jolla to North Hollywood.
Tournaments which use question sets produced by NAQT qualify the top fifteen percent (15%) of teams to the annual Middle School National Championship Tournament (MSNCT) in early May, or to the High School National Championship Tournament (HSNCT) in late May, depending on the question set. Additionally, the annual NAQT State Championship gives qualification to the highest-placed team that has not already qualified for the HSNCT. MSNCT- and HSNCT-qualifying tournaments are notated on the schedule with an asterisk (*).
The Partnership for Academic Competition Excellence (PACE) also hosts a smaller, more rigorous national tournament called the National Scholastic Championship (NSC). PACE individually contacts exemplary tournament hosts to designate them as affiliated events that qualify a top percentage of teams to the NSC. NSC-qualifying tournaments are notated on the schedule with a dagger (†).
