WSO Unified Schedule - All tournaments in Washington follow the WSO Unified Schedule (invitational, regional, state). See following link for FINAL rules: https://docs.google.com/spreadsheets/d/1WgsrwFJfoqCwtR6g3QS7TpYczMWv9FDarqwhdMcHSJs/edit?usp=sharing


(1) Coaches/teams: Updated schedule info will be posted to https://scilympiad.com/wa - be sure to keep abreast of any changes.

(2) Solar Power (B & C Divisions) has been added to the WSO Unified Schedule as a regularly-scored event (e.g., NOT as a Trial that does not figure into team scores). As Solar Power IS a trial at the 2023 national tournament, rules are included at the back of the 2022-23 rules manuals.


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. Normally, pilot/trial events are only conducted at the state tournament.

While Solar Power (B & C) is on the WSO Unified Schedule for 2022-23 (see above Note #2), it will be run at each Regional and State Tournament as a regularly-scored event (and not considered a WA trial event). Note that invitational tournaments may or may not run the event as not all invitationals run all events anyway - connect with the invitational tournament director to determine whether they will run Solar Power.

Number of Teams Advancing from Regional Tournament to State Tournament:

#s for 2022-23 will be posted ASAP after last regional tournament is run. See formula below for determination of advancing teams per regional tournament.

**B Division: Eastern - 5; NW - 11; SW - 4 (3-SW + 1-NW)

**C Division: Eastern - 5 (3-E + 2-NW); NW - 8; SW - 7 (4-SW + 3-NW)

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

**Formula for in-person tournament advancement from regional to state:

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 and 20 teams/division at the state tournament, 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).

**EXCEPTION based on tournament composition: If any tournament has non-geographic teams registered, above formula will be changed as follows:

Within the tournament, local and non-geographic teams will be considered separately in determining # of teams advancing to state with any rounding-up issues resulting in a higher overall # of teams advancing going in the local region's favor.

For example, based on overall tournament registration, 6 teams would advance to the state tournament. Based on local vs non-geographical team #s (and accounting for rounding up), 2.5 local teams and 3.75 non-geographical teams would advance, then local teams would have 3 teams advance and non-geographical teams would have 3 teams advance.
