The Short Answer

A big part of it is probably that the US school system may not be anywhere near as standardized as you may think. Even with a single state, school quality can vary dramatically, especially as they tend to be funded largely at the local level – so poor areas have less funding for schools than richer areas. Performance also varies a lot by state as well. I remember reading that if Massachusetts test scores were considered alone, they would rank very highly internationally. So you could be seeing the curriculum and results of students who are probably more advanced than average even in a high achieving state, and not realize that it's not necessarily the norm. _URL_0_
