Registrations for the 2016-17 season will be accepted starting August 1 until January 31, 2017. For teams wishing to compete in 2017, complete the registration form and return with payment OR purchase order. Team registration includes a rules manual and entry into regional tournament. Rules manuals are available by mid-September, so the earlier you get your registration form/payment or PO in, the sooner you'll receive your rules manual and can begin preparing for the tournament. NOTES: (1) Purchase of a rules manual from national Science Olympiad Store does NOT register your team for Washington Science Olympiad; (2) Teams registering with a purchase order must submit a hard copy of the purchase order to finalize registration; (3) Teams must formally withdraw registration by January 31, 2015, in order to obtain a refund -- rules manual must be returned intact for full refund; (4) Registered teams will receive a unique team number that will be used in ALL tournaments in the state -- invitational, regional, and state.

Schools registering 3 or more teams AFTER January 1 may register for $150 on a space-available basis. Complete registration form and send PO or payment.

Number of Teams Advancing from Regional Tournaments to State Tournament:

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

Numbers are determined after the registration deadline (Jan 31).

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).

2017 Season Teams Advancing to State (based on 22 teams):

Eastern regional (Spokane) - 5-B; 3-C

Northwest regional (Seattle Central) - 7-B; 8-C

Northwest regional (University of Washington) - 5-C

South Central regional (Yakima) - 5-B

Southwest regional (Vancouver) - 5-B; 6-C
