†Not applicable.
#Rounds to zero.
‡Reporting standards not met because data are available for less than 50 percent of the students.
1 TIMSS scores are reported on a scale from 0 to 1,000, with the scale average set at 500 and the standard deviation set at 100.
2 Data are available for at least 70 percent but less than 85 percent of students.
3 Data are available for at least 50 percent but less than 70 percent of students.
4 Met guidelines for sample participation rates only after substitute schools were included.
5 National Target Population does not include all of the International Target Population defined by the Trends in International Mathematics and Science Study (TIMSS).
6 Hong Kong is a Special Administrative Region (SAR) of the People's Republic of China.
7 Kuwait tested the same cohort of students as other countries, but later in 2007, at the beginning of the next school year.
8 Nearly satisfied guidelines for sample participation rates only after substitute schools were included.
9 National Defined Population covers 90 to 95 percent of National Target Population.
NOTE: Countries were required to sample students in the grade that corresponded to the end of 4 years of formal schooling, providing that the mean age at the time of testing was at least 9.5 years. Instructional times shown in this table are actual or implemented times (as opposed to intended times prescribed by the curriculum). Teachers provided class size and instructional time in mathematics and science. Instructional time was reported as hours per week; the hours per year shown in this table were computed by multiplying the hours per week by the number of instructional weeks per year. Schools provided the total instructional time used to calculate the percentage of time devoted to mathematics and science. Standard errors appear in parentheses.
