Online high school quizbowl tournaments are generally announced on the forums at https://www.hsquizbowl.org and on the Tournament Database on that same site.
Many NAQT tournaments are also being hosted online in the 2020-2021 school year. As of the writing of this guide, NAQT is still working on their online quizbowl platform. See the NAQT website for more details.
Pay attention to the tournament’s eligibility requirements. While online tournaments make it feasible for teams anywhere in the world to play against each other, PACE generally encourages tournament directors and players to pitch tournaments at existing local circuits.
