Trends in International Mathematics and Science Study Advanced 2008 TIMSS Advanced 2008 compared and contrasted the achievement of students enrolled in the most advanced secondary-school programs in mathematics and science. The study provided countries with an excellent opportunity to consider the effectiveness of their academic programs for students graduating from their secondary schools. The study also measured changes in students’ achievement between 1995 and 2008 for the countries that participated in both TIMSS Advanced cycles. TIMSS Advanced was administered in 1995 and 2008. For the advanced mathematics assessment, the target population consisted of students in their final year of secondary school who were taking, or had taken, courses in advanced mathematics. For physics, the target population was final-year secondary students who were taking, or had taken, courses in physics.
