Number of Teams per State

This is a list of states by the total number of teams registered in each state. These statistics are based on the official figures published at soinc.org.

National Tournament Invitations

Each state organization automatically receives one national tournament invitation for each division. States with the highest registration numbers by division are then awarded a second national tournament invitation, up to a total of 60 teams per division. Currently, there are 50 Division C and 47 Division B state organizations. Thus, the 10 states with the most Division C teams will receive two Division C national tournament invitations, and the 13 states with the most Division B teams will receive two Division B national tournament invitations. In the event that a state organization declines its national tournament invitation for either division, the invitation passes to the state with the highest team registration in that division that has not already been awarded a second invitation for that division.

Number of Teams per State

States with an asterisk (*) sent two Division B teams to nationals in 2024, and states with a dagger (^†) sent two Division C teams to nationals in 2024. States with superscript x (^x) sent no Division B team to nationals in 2024, and states with superscript y (^y) sent no Division C team to nationals in 2024. Note that the numbers shown in the table below represent combined Division B and C registrations, and therefore do not necessarily reflect the order in which states will be awarded two national tournament invitations.
