Frequently Asked Questions

Registration Process Show All

Why do I need to register my team?
All teams in Southern California must be registered with the State Science Olympiad in order to participate in any Science Olympiad Tournaments (Invitational, Regional, State, or National).
What is needed for registration?
Team registration is completed when the following four items are completed. A team's spot is not guaranteed until registration is completed.
  1. Filling out the online registration form.
  2. The school principal verifies the head coach and the school's participation in Science Olympiad.
  3. Membership dues paid to and received by Southern California Science Olympiad.
  4. Completion of any forms as required by the Regional (to be sent to Regional Science Olympiad).

The amount require for the membership dues and any additional required forms will be sent to the teams upon completion of the online registration form.
Registration Dates
Each year, Registration opens the Tuesday after Labor Day. The deadline for registration is 11:59 PM on December 2nd, or until all spots at the Regional site fills up, whichever comes first. Individual Regionals may accept additional team registrations after the deadline if logistics permit.
Which Regional can I go to?
Teams participating in Science Olympiad in Southern California must participate in a Regional within their county. In the case that the county which the school resides in does not have a Science Olympiad Regional Program, they may participate in a Regional Tournament with the permission of the Regional Director of that tournament and the State Director. Please see the county maps above.
How many teams can a school have?
If a team wishes to compete at an Invitational Tournament, it is required to compete in the Regional Tournament. The only exception is if the number of registered teams from the school exceeds the maximum number of teams per school allowed at that Regional Tournament. Even if the number of registered teams from the school exceeds the maximum number of teams per school allowed at the Regional or state Tournament, a school cannot have any of its teams participating at an Invitational Tournament on the same day as their Regional or State Tournament.

Note: For the 2024-2025 Season, there is a limit of 1 team per school to compete at the Orange County Regional Tournament. There is no limit to the number of teams from each school competing at other Regionals.
What is our information used for?
In order for the State and National Science Olympiad Program to track membership and school participation over time, all team registration data will be collected using a method that will provide real time updated information for the Regional planning team with minimal changes to the method schools register (by going to the Regional web page) while allowing the State Program to track membership information, to be shared with the Science Olympiad officials and only used in furtherance of promoting and improving the program.

Membership Dues Show All

What do the dues cover?
Registered teams are entitled to compete at their local Regional Tournament, space permitting, as well as the State and National Tournament if they qualify. Registered teams may also participate at Invitationals, but the membership fees do not cover admission to any Invitationals. Teams participating at Invitational Tournaments should check with the Invitational Tournament Director for any additional fees that may be required.
How much are the membership dues?
It is our intent to align the team membership dues in each of the regions within the Southern California State program jurisdiction, but the membership dues vary depending on the regional and the division.
Payment Methods
The entirety of the team membership dues will be sent to Southern California Science Olympiad and will be deposited into the state bank account.

A Paypal option is available for online payment. Purchase orders are not accepted, but team membership dues may be sent by mail. The specific account payable and mailing address information to be used will be provided when registration begins.
