Abstract
TIMSS & PIRLS International Study Center is a research center at Boston College that conducts a series of assessments in a number of countries to measure trends in mathematics and science achievement at the fourth and eighth grades. In general, TIMSS assessments include achievement tests as well as questionnaires for student, parent, teacher, school, and curricular. There are 63 participating countries and 14 benchmarking participants in TIMSS 2011, including 608,641 students, 49,429 teachers, 19,612 school principals, and the National Research Coordinators of each country. TIMSS data are valuable for researchers and analysts from all over the world, especially for those from participating countries, to conduct related studies to improve education.
