We’re excited to announce the Official California Invitational hosted by California Science Olympiad! Events will be run entirely by Science Olympiad alumni from SoCal and NorCal Science Olympiad, who will also serve as Event Writers and Event Supervisors for this year’s Regional and State Tournaments.

Tournament Information

The tournament will take place from January 20, 2026 to January 30, 2026 and is for both Divisions B and C. We will be running it in the satellite format. All build events will be run as trial events, and a comprehensive list of event modifications will be released as we near the start date.

Registration Details

Registration is now open and will close on January 19, 2026! Registration is $80 per team. There is no limit to the number of teams per division, and schools can register as many teams as they want. Note that all teams must be registered with their State Organization as per National Science Olympiad rules.
