That's annoying, isn't it? Testing is a very useful tool in determining appropriate education. It is disappointing when a school doesn't use it this way. I suppose it's possible that the teachers are still attempting to teach each kid at his/her level without relying on the testing. But it's a lot easier to use the tests. Then you can group kids at similar levels to help make sure everyone is appropriately challenged.
If I were you, I would follow your instincts and request further testing and then subject acceleration. Or just subject acceleration if they won't do further testing. Good luck!
