Number of Teams Advancing from Regional Tournament to State Tournament:

With switch from in-person to a statewide virtual regional tournament, the number of teams advancing will be based on 50% of each region/division with the following numbers for 2022:

B Division: Eastern - 4; NW - 19; SW - 4

C Division: Eastern - 3; NW - 18*; SW - 5

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

*Number changed 3/2/22 from 19 based on SW team mis-assigned to NW region; Correction didn't result in increase for SW.

Formula for in-person tournament advancement from regional to state (FYI for when in-person tournaments resume):

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).
