I guess the deeper question is, what is it what we expect schools to do for our children? Personally I think a profound focus on scoring well on test is shortsighted. while I do think it is important to learn basic math and languages skills I think it is equally important to learn to think and learn to learn. For some reason children are treated like they are similar to one and other while later in live you are able to choose different types of schools with different interest and different ways of learning. While I don't think a child should make profound live choices the idea that every child learns the same way and has the same background is just wrong and by doing so children will be left behind

Ask ten people and you'll get eleven different answers. Schools serve a lot of different masters, and also are used as proxy battlegrounds for both sides of a culture war.
