The Trends in International Mathematics and Science Study (TIMSS) and TIMSS Advanced are international comparative studies of student achievement.
TIMSS 2015 represents the sixth such study since TIMSS was first conducted in 1995. TIMSS is designed to align broadly with mathematics and science curricula in the participating countries. The results, therefore, suggest the degree to which students have learned mathematics and science concepts and skills likely to have been taught in school. In 2015, TIMSS was administered in 49 IEA member countries and 6 other education systems at grade 4, and in 38 IEA member countries and 6 other education systems at grade 8.
TIMSS Advanced assesses the advanced mathematics and physics knowledge and skills of students at the end of high school who have taken courses in advanced mathematics and physics. TIMSS Advanced 2015 represents the third such study since the first administration in 1995 and is designed to align broadly with the advanced mathematics and physics curricula in the participating countries. The results, therefore, suggest the degree to which students have learned the advanced mathematics and physics concepts and skills likely to have been taught in school. Nine countries participated in TIMSS Advanced 2015.
