Figure CL-14. Change in average TIMSS science scores of eighth-grade students in selected jurisdictions, by jurisdiction: 1995 to 2007


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

arrow pointing up Score is higher than U.S. score.
arrow pointing down Score is lower than U.S. score.
# Rounds to zero.
1 Met guidelines for sample participation rates only after substitute schools were included.
2 National Defined Population covers less than 90 percent of National Target Population (but at least 77 percent).
3 Hong Kong is a Special Administrative Region (SAR) of the People's Republic of China.
4 National Defined Population covers 90 percent to 95 percent of National Target Population.
5 National Target Population did not include all of the International Target Population defined by TIMSS.
6 Nearly satisfied guidelines for sample participation rates only after substitute schools were included.
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.
