Comparing students internationally with TIMSS

The Challenge 

To keep improving education, we need to know how students compare. The Trends in International Mathematics and Science Study (TIMSS) is part of a series of international studies, sponsored by the International Association for the Evaluation of Educational Achievement, to measure trends in student achievement. More than 60 nations participate in TIMSS.

Our Solutions 

  • Westat is conducting the U.S. component of the study. TIMSS collects comparative data on achievement in mathematics and science from samples of 4th and 8th graders.
    • In 2015, TIMSS also assessed grade 12 students who had taken or were taking calculus and physics.
    • In 2017, TIMSS piloted the new eTIMSS assessment to try out the digitally based assessment and to evaluate mode effects.
  • Additional information is obtained relating to the cultural environments, teaching practices, curriculum goals, and institutional arrangements that are associated with student achievement. Additionally, change is measured within and between countries in these areas by administering TIMSS every 4 years.

The Results 

  • Outcomes from TIMSS studies have been used to inform national and local policymakers, industry leaders, and educators, particularly about the comparisons across countries and over time in student achievement.
