I don't really put much stock in rankings. What's the big deal? Have you visited the school? Have they cut programs? Do they offer AP courses, extracurriculars...? Sometimes the less well ranked schools (like ours) actually get a lot more support than the other schools. I wouldn't move because of school rank unless the school really has undergone some severe changes that impact the programs and courses now offered. But, moving for a house that fits your family better makes sense.
