Document Number: 6563Highlights from the Trends in International Mathematics and Science Study (TIMSS) 2003 - The 2003 TIMSS study provides information on the performance in math and science by 4th and/or 8th graders in 46 countries. In some nations, changes in student achievement in these subjects can be tracked from 1995 to 2003. Findings: In 2003, U.S. 4th and 8th graders exceeded the international average, but their performance appeared less stellar when compared to just their peers in OECD-member countries. American 8th graders made substantial gains in average math performance between 1995 and 2003, while U.S. 4th graders’ scores remained level over this same period. The report also is broken out by chapter.
