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. A draft schedule for the season is typically posted in early October with opportunities for coaches to comment before it is finalized end of October.
This season two events—different from the national Rules Manual—will be scored as regular events in all regional and state tournaments: Sustainable Energy (Divisions B/C, replaces Wind Power) and Quantum Quandary (Division C only, additional event). Rules are linked.
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.
