TIMSS (Trends in international mathematics an science study) results 2019

The Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that measures trends in mathematics and science achievement at the 4th and 8th grades every 4 years. TIMSS is designed to align broadly with mathematics and science curricula in the participating education systems and, therefore, to reflect students’ school-based learning.

The Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that measures trends in mathematics and science achievement at the 4th and 8th grades every 4 years. TIMSS is designed to align broadly with mathematics and science curricula in the participating education systems and, therefore, to reflect students’ school-based learning. The United States has participated in every administration of TIMSS since its inception in 1995, and the study provides valuable information on how U.S. students compare to students around the world.

In 2019, a total of 64 education systems participated in TIMSS at the 4th grade, while 46 systems participated at the 8th grade. Most of these education systems are member countries of the International Association for the Evaluation of Educational Achievement (IEA), the group that sponsors TIMSS internationally; a small number at each grade are nonmember subnational entities that have joined TIMSS as “benchmarking participants.” Both groups are included in the discussion of results and counts of education systems.
