Trends in International Mathematics and Science Study

The Trends in International Mathematics and Science Study (TIMSS) is a series of international assessments of the mathematics and science knowledge of students around the world. The participating students come from a diverse set of educational systems (countries or regional jurisdictions of countries) in terms of economic development, geographical location, and population size. In each of the participating educational systems, a minimum of 4,500 to 5,000 students are evaluated. Furthermore, for each student, contextual data on the learning conditions in mathematics and science are collected from the participating students, their teachers and their principals via separate questionnaires.
