| NOTE: Class size and implemented instructional time for mathematics provided by teachers; total instructional time provided by schools. TIMSS scores are reported on a scale from 0 to 1,000, with the scale average fixed at 500 and the standard deviation fixed at 100. Countries were required to sample students in the grade that corresponded to the end of 8 years of formal schooling, providing that the mean age at the time of testing was at least 13.5 years. Detail may not sum to totals because of rounding. Standard errors appear in parentheses. | |||||||||||||||||||||||||||
