How often is the TIMSS assessment conducted?

The TIMSS (Trends in International Mathematics and Science Study) assessment is conducted every four years. This schedule allows for the collection of comparable data over time regarding the performance of students in mathematics and science across various countries. The four-year interval enables researchers and policymakers to track trends in educational outcomes and to examine the effectiveness of different education systems and practices. The data gathered during each cycle helps to inform improvements in education and provides insights into the factors contributing to student achievement in these crucial subject areas.
