U.S. fourth- and eighth-graders improved their math scores in a closely watched international test, but continued to lag well behind peers from top-performing Asian countries. The U.S. and other governments on Tuesday 11 the results of the test, Trends in International Mathematics and Science Study, the world’s largest assessment of international achievement. Some 425,000 students in almost 60 countries took the exam, administered every four years, starting in 1995.

U.S. fourth-graders on average scored 529 in 2007, up from 518 in both 2003 and 1995. The results are reported on a zero to 1,000-point scale, with 500 16 the international average. Top-performing China scored 607. U.S. eighth-graders ranked No. 9 in math with a score of 508, behind many of the 17 Asian countries atop the fourth-grade chart. “In math, the U.S. is making 18 progress,” says Michael O. Martin, one of the directors of the study at Boston College, which 19_ the test.
