Participation

Back

In 2015, TIMSS Advanced was administered in 9 countries.² A list of all countries that participated in 2015, 2008, and 1995 is available here.

The students who participated in TIMSS Advanced were students in their final year of high school who had taken or were taking advanced mathematics or physics courses. The percentage of students (of the overall student population of the same age) who participated in TIMSS because they take such courses is referred to as the "coverage index." Because the coverage index varies in each subject and across countries, results will be reported with those percentages.

For six countries, changes in achievement can be documented over the last 20 years, from 1995 to 2015. For those that began participating in TIMSS Advanced in 2008, changes can be documented over a shorter period of time—though those results are not shown because the United States did not participate in TIMSS Advanced in 2008. The TIMSS Advanced participation table shows the countries and other education systems that participated in TIMSS Advanced 2015 as well as their participation status in the earlier data collections in 1995 and 1998.

² "Countries" are complete, political entities. In 1995, "other education systems," representing a portion of a country, national, kingdom, or emirate (e.g., the Flemish Community of Belgium, the Hong Kong Special Administrative Region, and Scotland), also participated in TIMSS Advanced. All of the countries and other education systems that have participated in TIMSS Advanced are members of the IEA and, as such, are reported together in tables and figures, where applicable. (Non-member education systems would otherwise be designated as "benchmarking participants" and reported separately, as is done for TIMSS.)
