You may not be able to effect a change in time for your decision, but if I were you I would be writing and speaking to the school board members, school superintendent, and relevant assistant supers (if any). Politely, of course.
As you can imagine, this is not a popular policy with the parents. Every year it is the subject of heated debate in school board meetings. It all comes down to finances. Using this scheme, all the classrooms in all the schools are near 100% capacity. That way the district employs only as many teachers as necessary and maintains only as many buildings as necessary. Yes, the teachers are jerked around like the students and moved from school to school or "let go" to maintain optimum efficiency.
