Figure CL-13. Change in average TIMSS science scores of fourth-grade students in selected jurisdictions, by jurisdiction: 1995 to 2007
Score is higher than U.S. score.
Score is lower than U.S. score.
1 Hong Kong is a Special Administrative Region (SAR) of the People's Republic of China.
2 Did not satisfy guidelines for sample participation rates.
3 National Target Population did not include all of the International Target Population defined by the Trends in International Mathematics and Science Study (TIMSS).
4 Only Latvian-speaking schools (LSS) are included.
5 Met guidelines for sample participation rates only after substitute schools were included.
6 National Defined Population covers less than 90 percent of National Target Population (but at least 77 percent).
7 National Defined Population covers 90 percent to 95 percent of National Target Population.
8 Estimates for New Zealand have been computed for students taught in English only, which represents 98 to 99 percent of the student population.
NOTE: Selected jurisdictions include those that participated in both TIMSS 1995 and TIMSS 2007. Average science scores are reported on a scale
from 0 to 1,000. Tests for statistical significance take into account the standard errors for scores in both years. Because the size of standard errors
can vary, a small difference between the scores of one jurisdiction may be significant while a larger difference between the scores of another
jurisdiction may not be significant. Detail may not sum to totals due to rounding.
