! Interpret data with caution, estimates are unstable. The coefficient of variation is greater than or equal to .3 but less than .5.
‡ Reporting standards not met. Either data are insufficient to report achievement or the coefficient of variation is greater than or equal to .5.
*p <05. Average score is significantly higher than other sex's average score.
1 Met guidelines for sample participation rates only after substitute schools were included.
2 National Defined Population covered 90 percent to 95 percent of National Target Population.
3 National Defined Population covered less than 90 percent of National Target Population (but at least 77 percent).  
4 National Target Population did not include all of the International Target Population defined by the Trends in International Mathematics and Science Study (TIMSS).  
5 Hong Kong is a Special Administrative Region (SAR) of the People's Republic of China.
6 Kuwait tested the same cohort of students as other countries, but later in 2007, at the beginning of the next school year.
