*p <05. Average male - female score point difference is statistically significant.
¹National Defined Population covered less than 90 percent of National Target Population (but at least 77 percent).
²National Defined Population covered 90 percent to 95 percent of National Target Population.
³National Target Population did not include all of the International Target Population defined by the Trends in International Mathematics and Science Study (TIMSS).
⁴Hong Kong is a Special Administrative Region (SAR) of the People's Republic of China.
⁵Kuwait tested the same cohort of students as other countries, but later in 2007, at the beginning of the next school year.
⁶Met guidelines for sample participation rates only after substitute schools were included.
NOTE: The National Target Population includes all students enrolled in the grade that represents 8 years of formal schooling, counting from the first year of the International Standard Classification of Education (ISCED97) level 1, provided that the mean age at the time of testing is 13.5 years. Schools included in the National Target Population may be excluded from the population of schools that are ultimately sampled for the assessment for various reasons, including having a geographically remote location, having too few students, or being specifically for special needs students. This final population from which schools will be sampled is the National Defined Population. The male-female score point difference is calculated by subtracting the average scores of females from the average scores of males. Apparent differences may not be statistically significant. Detail may not sum to total due to rounding. Standard error is noted by s.e.
