TIMSS – Trends in International Mathematics and Science Study

TIMSS is a large-scale international assessment that has been conducted every four years since 1995 to measure the academic achievements of 4th and 8th-grade students in mathematics and science. The study provides a comparative analysis of teaching quality across different countries, helping education policymakers, researchers, and practitioners assess and improve educational systems.

• For education policymakers, TIMSS provides evidence-based data on national education policies, curriculum effectiveness, and international competitiveness. It helps governmental institutions identify the strengths and weaknesses of STEM education and implement targeted reforms.

• For schools, TIMSS offers valuable insights into how school resources, teaching strategies, and students’ socioeconomic backgrounds affect academic performance. This information enables schools to improve the quality of education and allocate resources more effectively.

• For teachers, TIMSS analyzes teaching methods, professional development needs, and classroom practices. Its findings offer teachers access to international best practices, supporting the improvement of instructional approaches and the development of more effective pedagogical strategies.

• For students, TIMSS results are important not only because they assess students' knowledge and problem-solving skills but also because they examine their motivation, engagement, and attitudes toward STEM subjects. These insights contribute to enhancing the learning process and improving students' self-efficacy.

It is essential to note that TIMSS goes beyond measuring academic achievement — it also collects contextual data on curricula, school environments, and instructional practices, making it a key tool for educational research and systemic improvement.
