† Not applicable.  
1 Did not satisfy guidelines for sample participation rates.  
2 Met guidelines for sample participation rates only after substitute schools were included.  
3 National Defined Population covers less than 90 percent of the National Target Population (but at least 77 percent).  
4 National Target Population did not include all of the International Target Population defined by the Trends in International Mathematics and Science Study (TIMSS).  
5 Hong Kong is a Special Administrative Region (SAR) of the People's Republic of China.  
6 National Defined Population covers 90 percent to 95 percent of the National Target Population.  
7 Indonesia and Italy were unable to complete the steps necessary for their data to appear in TIMSS 1995 report (Peak, 1996).  
8 Data not shown because of unapproved sampling procedures at classroom level and failure to meet other guidelines.  
9 Kuwait tested the same cohort of students as other countries, but later in 2007, at the beginning of the next school year.  
10 Only Latvian-speaking schools (LSS) were included.  
11 Mexico participated in the testing portion of TIMSS, but chose not to release its results at grades 3 and 4 in the international report.  
12 Nearly satisfied guidelines for sample participation rates only after substitute schools were included.  
13 Estimates for New Zealand have been computed for students taught in English only, which represents 98 to 99 percent of the student population.  
NOTE: Science scores are reported on a scale from 0 to 1,000. The TIMSS 1995 average scores were rescaled to allow for trend analysis. For more details, see appendix A of Provasnik, Gonzales, and Miller (2009). The tests for significance take into account the standard error for the reported difference. Thus, a small difference between the United States and one jurisdiction may be significant while a large difference between the United States and another jurisdiction may not be significant. Standard error is noted by s.e.
