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. 

After December 1, additional teams may register on a space-available basis.  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.

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.   When registering on https://scilympiad.com/wa, be sure to finalize registration by completing the payment screen. With applied discount, waivers will show $0 due; $100 discount will show $150 per team due.

NOTE: While WSO generally posts a unified schedule with the expectation that all tournaments in the state - including invitationals - adhere to the unified schedule, given COVID restrictions, the WSO board is not requiring use of the following schedule by invitational tournaments, but has recommended it be used to assist Washington teams in identifying events students will compete. 

FINAL SCHEDULE with summary of event/tournament changes (pdf). "Final" WSO schedule for regional and state tournaments... subject to change. Note the date at the bottom of the posted schedule to ensure you have the most recent (11/5/20). Excel file of schedule only.

The WSO board adopted multiple event changes for the virtual tournament - link provided in above pdf. Click here for complete documentation of tournament/event modifications. This file provides links to event rules that are NOT included in the national Science Olympiad manual download. Open the document and download event files.

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.

C Division: Environmental Chemistry; WiFi Lab: (Rules, Checklist, Scoring Sheet, Transmitter Construction Guide)

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.) Even though file date may indicate 2020, ok - will be used in 2021 state tournament.

Number of Teams Advancing from Regional Tournaments to State Tournament:

With regional tournaments running via virtual option, the state tournament will be same. One benefit of this is that WSO is not bound by facilities restrictions, meaning the state tournament can host more teams than usual. Subsequently, for the 2021 state tournament, one half of each geographic region's teams will advance to the state tournament (allowing for more teams to compete at the state level).

The WSO policy of no more than 2 teams from one school advancing to the state tournament still applies.


The information below would apply to in-person tournaments after the 2020-21 season (if/when the WSO board confirms we CAN conduct in-person tournaments). For now, IGNORE this info:   

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).
