There will be an Amelia High School with at least three small schools on its campus. There will be a Glen Este High School with at least three small schools of choice. The purpose is to give as many options as we can to all students. Repeating programs limits choices. No one has ever said they have to be half and half.
Teachers can combine and collaborate to create the very best small schools of choice.
But this is not a structural nor contextual requirement. By not participating in a design team now, you are limiting your future options. Once the schools are approved and ready to be fully staffed, you may indeed be assigned to a school based on its staffing needs. Staff may cross over, but only depending on need. Schools of choice may end up sharing some of the non-core staff required for graduation, like health, physical education, fine arts, and technology.
