US scores above average in math, science, still lags in math
American students may not be reading any better, but they’re moving up in rankings of educational achievement worldwide because many of their peers in other countries are performing worse. And while their math performance may not be getting any worse, 15-year-olds in the United States still lag the scores in dozens of other countries.
Overall, the latest global snapshot of student achievement shows American students scoring above average in reading and science, but below average in math. Average U.S. scores didn’t change significantly in any of those subjects since 2015.
The 2018 Program for International Student Assessment, or PISA, shows a number of Asian school systems at the top. The best-performing across all three measures was a group of four Chinese provinces.
