Tournaments & Schedules

Events List & Schedule

All Division B and Division C tournaments (Invitational, Regional, and State) in Washington state will follow the WSO Unified Schedule. Tournaments may add additional time blocks as needed to accommodate teams and their venue. Coaches have opportunities to comment before it is finalized end of October.

Unified Schedule (2027)

Please see national Science Olympiad Rules Changes/Corrections and Rules Clarifications/Frequently Asked Questions (FAQs)—which apply at WSO tournaments—as well as resources for preparing for events on our page of resources for teams.

Code Craze – Cybersecurity (Division C trial), Quantum Supremacy (Division C trial), and Game Agent (Trial, Division B) are Washington-specific events not counting in team scores. The event rules for these events are linked directly on the schedule. Visit our Resources page for additional resources, including tests and answer keys from previous years. Protein Modeling will be an official Division C event, while Protein Builder will be a Division B trial event for WA. Hydraulics will be trialed at WA state tournament and the corresponding rules are featured in the trial event section of the National rule manual. One can learn the topics and its build by searching for inexpensive STEM hydraulics kits or hydraulic machines online.

Invitational Tournaments

All teams registering for an invitational tournament must be registered with their state Science Olympiad (i.e. Washington Science Olympiad if you are in Washington State). Please check back regularly for registration links and new tournament information.

Other invitational tournaments outside of Washington state are listed on the national website, which is updated periodically. These tournaments may follow a different event schedule and may feature events not included on the Washington event slate.

Regional Tournaments

Washington teams register with their geographic location. No more than 6 teams from one school may register prior to December 2; then on space-available basis, additional teams may register. Early registration is strongly encouraged for Northwest region teams as capacity may be limited. See the Registration page for deadlines and more details.

Numbers of teams advancing from each Regional Tournament to the State Tournament will be announced after the last Regional Tournament date. Please see our Policies page for how this number is calculated.
