Honestly good teachers are no longer able to do what they do best. Schools period suck now days. Teachers don't have the time or ability to do what they used to do. If you're in a bad area the teachers spend more time redirecting kids then they do teaching. Gifted kids will always excel, they can figure things out on there own. Kids who need help suffer more and more and never truly get the help they need. You're lucky if your kids gets properly tested and intervention, and even luckier if they actually if the teachers follow that intervention. (Yes I know by law they have to follow the IEP's, doesn't mean they will)
If your district has school choice you will have to find out the deadlines to submit the request for a certain school. Sadly midyear you may not get a choice.
