Still, the 2011 results do show a slight improvement over the same tests in 2007. Back then, the US placed 11th and 10th in fourth grade and eighth grade mathematics respectively, with the nation also achieving 8th and 11th places in science exams. If you're wondering where China ranks on the global scale, you'll have to keep guessing: mainland China hasn't taken part in any of the tests. And despite the fierce competition, the results show that the United States is still well above the global average.
