Fourth Grade:
 In 2003, U.S. fourthgrade students scored 518, on average, in mathematics, exceeding the international average of 495 (table 2 and table C1 in appendix C). U.S. fourthgraders outperformed their peers in 13 of the other 24 participating countries, and performed lower than their peers in 11 countries.
 In comparison to students in the other 10 OECDmember countries participating in the fourthgrade TIMSS assessment, U.S. fourthgraders outperformed their peers in mathematics in five countries (Australia, Italy, New Zealand, Norway, and Scotland) and were outperformed by their peers in the other five countries (BelgiumFlemish, England, Hungary, Japan, and the Netherlands) (table 2).
Eighth Grade:
 In 2003, U.S. eighthgraders scored 504, on average, in mathematics. This average score exceeded the international average as well as the average scores of their peers in 25 of the 44 other participating countries (table 3 and table C2 in appendix C). U.S. eighthgraders were outperformed by students in nine countries: five Asian countries—Chinese Taipei, Hong Kong SAR, Japan, Korea, and Singapore—and four European countries—BelgiumFlemish, Estonia, Hungary, and the Netherlands.
 In comparison to their peers in the other 12 OECDmember countries participating in the eighthgrade TIMSS assessment, U.S. eighthgraders outperformed students in mathematics in two countries (Italy and Norway) and were outperformed by their peers in five countries (BelgiumFlemish, Hungary, Korea, Japan, and the Netherlands) (table 3).
