Tournament Info: 2025-2026 Season

All the latest information for the various Division B & C tournaments can be found here.

Schools MUST register to be eligible to compete in any of the events described below!

Before registering your team, review the Science Olympiad policies, including the team formation/roster rules and the expectations of students, coaches, AND parents.

Schools may register any number of teams in Division B and C (in order to compete at any tournament - Invitational, Regional, State, or National - the team must be registered with HSSO). However, schools may only enter a maximum of 2 teams in each Division that can be eligible to compete to qualify the school for the State Finals in that Division. tournament. A 3rd and/or 4th team from each school may be allowed to participate in Regional Tournaments, granted there is still space in the tournament and that those schools have officially registered/paid for those teams with HSSO. Schools that qualify to advance to the State Finals Tournament in each division may only compete with 1 team at the State Finals Tournament.

As per National Science Olympiad policy, for schools with two teams, each student must be assigned to one team and may NOT compete for both teams. Additionally, students may only compete in one division throughout a single season, there is no switching of divisions allowed. HSSO will be adapting this policy such that a student (9th grader) that is eligible for their previous B team and their current High School's C team may switch between the two divisions for non-qualifying tournaments, but must stick with one division when they compete for an qualifying tournament (Regionals, States).

THE LEAGUE SYSTEM IS NO LONGER IN EFFECT FOR THE 2025-2026 SEASON.

All teams will be competing with each other at Invitational, Regional, and State Tournaments.

The first place school in Division B and Division C at the State Tournament from the Championship League will advance to represent Hawaii at the National Tournament.

Teams are encouraged to compete in all events offered at a tournament and their overall team performance evaluated in all of those events; teams that do not compete in an event do so at a disadvantage to their overall ranking. At the State Finals all 23 Science Olympiad events will be run as described in the current season rules manual. See the State Finals page for specific information regarding event blocks in early March 2026.

For inquires regarding tournament details and logistics (including event offerings, schedule, etc), please contact the regional or state tournament director: director@hsso.org, hssostatetournamentdirector@gmail.com

Invitationals

Practice tournaments that are organized by Science Olympiad teams. Results from these tournaments do not affect Regional rankings or State Finals qualification. These events are purely developmental to gain some experience. Schools must be registered with HSSO in order to be eligible to participate. Schools may only register as many teams for an invitational as they have registered and paid for with HSSO for the season.

Invitational Tournaments sanctioned by HSSO have the autonomy to set their own registration fee for their tournament, event availability, and event block/schedule.

More information and a list of scheduled Invitational Tournaments for 2025-2026 can be found at the Invitational Tournament Page.

Regional Tournaments

Official HSSO tournaments used as a qualifier for the State Finals Tournament. Schools must be registered with HSSO in order to compete. A maximum of 2 teams per school may compete in a Regional tournament.

HSSO intends on hosting Division B and Division C Regional Tournaments on Kauai, Maui, Oahu, and the Big Island. All Regional Tournaments will be in-person, single location tournaments. The tentative dates for Regional Tournaments can be found on the Regional Tournaments Page.

Additional information and details regarding events and schedule of Regional Tournaments will be published and communicated to coaches as plans for each Regional Tournament are finalized. Event group schedules will follow the National Tournament schedules.

The State Director will assign teams to Regional Tournaments according to the team's registration. The State Director will determine how many schools from each league will advance from each Regional Tournament to the State Tournament.

Regardless of the number of schools advancing from each Regional to the State Tournament, a school advancing to the State Tournament in either league must have fielded a team which competed in at least two-thirds (2/3) of the events at their Regional Tournament, if a Regional Tournament is held for their assigned Region.

Continuing for 2025-2026: A team may still participate and compete at the State Finals, even if they do not qualify for the State Finals through their home regional. Teams competing in this way must have competed in at least two-thirds (2/3) of the events at their Regional Tournament and are effectively "auditing" the State Finals; their performance will not make them eligible for awards, medals, or advancement to the National Tournament.

Visit the Regional Tournaments Page for more information.

State Finals

Schools must qualify for this tournament from a Regional. The winning school from Division B and Division C in the Championship League will receive invitations to represent Hawaii at the National Tournament.

For the 2025-2026 Season:
