While school districts consolidate relatively often, especially in rural areas, they don't split. I can't think of one instance where a school district split into multiple districts. Intra-district attendance boundaries yes - those are determined by the school board and leadership. But a new district seceding from another? Not going to ever happen because of what it would do to the tax base.
The closest I can think of was that neighborhood in Edina that is in the Hopkins district, and wanted to secede to go to the Edina district. That didn't happen and for the exact reason I stated above.
