Figure CL-7. Change in average TIMSS mathematics scores of fourth-grade students in selected jurisdictions, by jurisdiction: 1995 to 2007


Change in average TIMSS mathematics scores of fourth-grade students in selected jurisdictions, by jurisdiction: 1995 to 2007

arrow pointing up Average score was higher than the U.S. average score.
arrow pointing down Average score was lower than the U.S. average score.
1 Hong Kong is a Special Administrative Region (SAR) of the People's Republic of China.
2 Met guidelines for sample participation rates only after substitute schools were included.
3 National Defined Population covers less than 90 percent of National Target Population (but at least 77 percent).
4 Did not satisfy sampling participation rates.
5 National Target Population did not include all of the International Target Population defined by the Trends in International Mathematics and Science Study (TIMSS).
6 Only Latvian-speaking schools (LSS) are included.
7 Nearly satisfied guidelines for sample participation rates only after substitute schools were included.
8 National Defined Population covers 90 percent to 95 percent of National Target Population.
9 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 mathematics 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.
