Twin Oaks Elementary School Reviews

By a Parent on

The school is very much interested in covering their own butts when it comes to accountability to the state. They also have a strong reputation for bullying problems that go on for years unresolved. And if you happen to be a parent who challenges this or even speaks up, you apparently become blacklisted within the administration at least. Then coincidentally, attendance records start to not be kept accurately or something else of that nature. This is a very poorly run school.
