That's surely where the financing model is important. Schools here get money based on the number of students, and the dispatch of teachers is done at a region level depending on the needs. A school with "bad" teachers would just get better teachers if it was warranted (in practice, everyone understands why kids are failing, and they'll send low experience teachers instead, because fuck them, I guess)
