Without a doubt one of the worst school districts on the face of the planet. If you're related to the small group that runs things, your child is set. Otherwise, your child will be treated as a second class citizen, and stuck in a class taught by one of the many lousy teachers they have who should have retired eons ago.
Pay no attention to the test scores. This school is 90% little rich white kids who are going to do well on standardized tests regardless of what school they attend, and Wall students actually perform worse on those tests than students at similar schools.
