2020-21 Fees: Waivers and discounts for 2019-20 registered teams take the place of regular fee schedule.  Schools new to Science Olympiad (or schools that have not registered with WSO within last 5 years) may qualify for a registration waiver for one team. Contact State Director for info. If registering more than one new school team, the returning team fee applies ($250 per additional team) If registering 3rd or more teams after December 1, the fee is $150 per team (on a space-available basis only - check with State Director for availability before submitting registrations).

No more than 6 teams from one school may register prior to December 2. All schools/teams MUST register for a tournament in the school's geographic region. 

After December 1, additional teams may register on a space-available basis with possibility to move all registered teams to a different geographic loaction. After December 1, 3rd or more teams from a school may register at the discounted $150 fee; 2nd teams from a school will pay full $250 registration fee. Contact State Director for ability to add/switch.

Note that 2019-20 registered teams qualifying for registration waivers or discounts may only take advantage in the 2020-21 season - waivers/discounts will not be carried forward to the 2021-22 season. For schools receiving waivers/discounts that register MORE teams than last year, the full registration fee ($250/team) applies for those additional teams only and PO or payment will be required to finalize registration.

General Information/FAQs

Latest News




NOTE: The schedule below is from 2019-20. These events will continue into the 2020-21 season. The WSO board is reviewing the schedule for possible changes. But as the current tournament option Washington plans to host for 2021 regionals are Satellite tournaments, most likely this (or similar) schedule will NOT be used. But we may try to use parts of it in creating Satellite tournament schedules. For now, IGNORE the WSU Unified Schedule. 

If/when WSO is able to run in-person tournaments, the following info will apply. All tournaments in Washington state adhere to the same schedule in order to provide continuity of competition from the invitational to regional to the state tournament. Click on the link below for the most recent schedule. Contact State Director if you are unable to open the document.

FINAL SCHEDULE - "Final" WSO Unified Schedule ... subject to change. Note the date at the bottom of the posted schedule to ensure you have the most recent (2/21/20).

For C Division, note that Code Analysis has replaced Ping Pong Parachute - click on event title link for rules. [B Division WILL still run Ping Pong Parachute.]

There is SOME flexibility for Tournament Directors discretion to meet the needs of their tournament site. Tournament Directors MAY adjust schedule as long as coaches are notified by January 16.


Pilot and trial events are selected by the WSO Board of Directors based on coach feedback/request and/or trial events that are scheduled to become regular events in later years on the national SO lineup.


The WSO board is considering including a solar vehicle pilot event for 2020-21 - check back for more info later. 

Teams advancing to the state tournament should use rules posted to WSO web site - click above links - to ensure you have the version being used in Washington. (Do not use the rules on the national Science Olympiad web site.)

Number of Teams Advancing from Regional Tournaments to State Tournament:

With COVID restrictions on what tournaments can be run, at this time, no specific information is available on when or where (or whether there) will be a state tournament - at least in the traditional way. The information below would apply if/when the WSO board confirms we CAN advance teams in this way. For now, IGNORE.  


The number of teams advancing to the state tournament from regional tournaments: 22 teams per division

Numbers are determined after the registration deadline (Jan 15).

To determine the number of teams advancing from regional tournaments to the state tournament in each division, the following formula shall be applied:



Resulting fractional numbers will be rounded down (.1 to .4) or rounded up (.5 to .9).


If there are 79 B teams registered statewide and 20 B teams can be accommodated at the state tournament.  There are four regions:

Region 1 has 18 teams

Region 2 has 24 teams

Region 3 has 23 teams

Region 4 has 14 teams


Based on the formula above, the following number of teams should* advance to the state tournament:

Region 1 will send 5 teams (formula3

Region 2 will send 6 teams formula4

Region 3 will send 6 teams formula5

Region 4 will send 4 teams formula6

*In years when rounding up results in more teams being eligible for State than the tournament is able to accommodate (as identified in the above example, where 21 teams should advance), the region/s with the greater number of teams will be given priority.  In the example above, this would be the actual number of teams that advance to the state tournament based on only 20 teams being accommodated:

Region 1 – 5 teams
Region 2 – 6 teams
Region 3 – 6 teams
Region 4 – 3 teams (even though the formula allowed for rounding up to 4 teams, with only 14 teams, this region has the fewest number of registered teams; therefore, the other regions are given priority in advancing to the state tournament).
