Figure CL-8. Change in average TIMSS mathematics scores of eighth-grade students in selected jurisdictions, by jurisdiction: 1995 to 2007
Average score was higher than the U.S. average score.
Average score was lower than the U.S. average score. 1 Met guidelines for sample participation rates only after substitute schools were included. 2 Hong Kong is a Special Administrative Region (SAR) of the People's Republic of China. 3 National Defined Population covers less than 90 percent of National Target Population (but at least 77 percent). 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 the Trends in International Mathematics and Science Study (TIMSS). 6 Sampling issues identified by TIMSS. See TIMSS 1995 report for details. 7 Nearly satisfied guidelines for sample participation rates only after substitute schools were included. 8 Did not satisfy guidelines for sample participation rates.
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.
