What is the main focus of TIMSS, one of the IEA's assessments?

The main focus of TIMSS (Trends in International Mathematics and Science Study) is specifically on assessing mathematics and science achievement among students in various countries. It aims to evaluate what students know and can do in these two critical subject areas at different grade levels, typically at fourth and eighth grades. By analyzing the results, TIMSS provides valuable insights regarding educational practices and outcomes in mathematics and science, allowing for comparisons across nations and helping to identify successful strategies or areas needing improvement.

This assessment does not center on reading skills, vocational skills, or art and music education, as those are distinct educational domains that are evaluated through different assessments and frameworks. Thus, TIMSS stands out with its exclusive emphasis on mathematics and science learning outcomes.
