Regionals Event Registration
- The National Science, History & Geography Bee Regional Tournaments are open to all grade levels with grade-based divisions for middle and elementary school students, plus Varsity and Junior Varsity divisions for high school students.
- National History Bee & Bowl Regional Tournaments have team (Bowl) and individual (Bee) competitions and are also open to all grade levels, though 8th grade-and-under teams may play in the Junior Varsity Division unless there are at least three middle school or elementary school teams to create a separate division.
2025-2026 National Science, History & Geography Bee Regional Tournaments
For the 2025-26 school year, regionals are open to students in all grade levels (K-12). Students in grades K-8 must qualify via the Online Regional Qualifying Exam while students in grades 9-12 can register directly. Students may typically compete at any site (including sites outside their state) as long as they are qualified (if applicable) and have not already played that tournament’s designated set of questions. Tournaments noted as “Closed” are open only to the students specified on that tournament’s page.Â
Note: Students may only play each subject ONCE per question set (Red, White, Blue, and Gold), meaning each student can play a maximum of four Science, History & Geography Bee Regionals for each subject. However, students may also compete in National History Bee at National History Bee and Bowl Regionals on each of those three sets (C, B and A) for a total of up to seven History Bee regionals per school year. The Red, White, and Blue Sets have a comparable level of difficulty; the Gold Set is slightly more challenging as it is meant as a tune-up for Nationals.
