*p < .05. Percentage is significantly different from the U.S. percentage at the same benchmark at the .05 level of statistical significance.
1 The physics coverage index is the percentage of the corresponding age cohort covered by students in their final year of secondary school who have taken or are taking physics courses. The corresponding age cohort is determined for education systems individually. In the United States, the corresponding age cohort is considered 18-year-olds. For additional details, see the Technical Notes available at http://nces.ed.gov/timss/timss15technotes.asp.
2 Did not satisfy guidelines for sampling participation rates.
NOTE: Education systems are ordered by the percentage of students reaching the Advanced international benchmark. The international median represents all participating TIMSS Advanced education systems, including the United States. Standard error is abbreviated as s.e.
