Figure CL-12. Percentage of eighth-grade students reaching the TIMSS international benchmarks in science, by jurisdiction: 2007
*p < .05. Percentage reaching advanced benchmark is measurably higher than U.S. percentage.
# Rounds to zero.
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 90 percent to 95 percent of National Target Population.
4 National Target Population does not include all of the International Target Population defined by the Trends in International Mathematics and Science Study (TIMSS).
5 National Defined Population covers less than 90 percent of National Target Population (but at least 77 percent).
6 Kuwait tested the same cohort of students as other countries, but later in 2007, at the beginning of the next school year.
NOTE: Jurisdictions are ordered by the percentage of students who reached the advanced international benchmark on a scale of 0 to 1,000.
The International Association for the Evaluation of Educational Achievement (IEA) set international benchmarks for TIMSS based on an analysis
of score points. Students who did not reach benchmarks are not shown nor are students whose placement relative to the benchmarks was
uncertain. Because IEA benchmarks are anchored by scores, it is possible to calculate the percentage of students who reach each benchmark's
score threshold with accuracy but not the percentage distribution of students by benchmarks. Apparent differences may not be statistically
