Agenda is up for September meeting. Sawtooth will only lose Lighthouse if they approve all the petitions. I never seen any turned down. Most are based on proximity. The Sun Valley Community school wants to go down to 1a d2 from 2a. Only play volleyball and Basketball in that league and have not been competitve in either sport for some time.
Murtaugh is petitioning down but next cycle will have 120 kids based on enrollment in Grade school. Castleford border line old enrollment, but athletics not that great.
Canyone Ridge petitioning down to 4a. Rexburg, Idaho falls and Pocatello or to the Treasure Valley would be a cost. I am not familar with Northern Idaho or treasure valley but I would say Proximity is the main reason schools petition up or down. Competitive not doing well is for some. But who plans to go up or down is already on the agenda. I have yet to see any petition denied. One was real close though.
Valley back to 2a. Sometimes will see dropping or rising enrollments in Jr High and Grade school as reason. See what state will do.
