TIMSS is a flagship study of IEA. Directed by the TIMSS & PIRLS International Study Center at Boston College, TIMSS is an international assessment of student achievement in mathematics and science at fourth and eighth grades. The study is designed to capture the breadth and richness of these subjects as they are taught in the participating counties. The study collects detailed information about curriculum and curriculum implementation, together with empirical information about the contexts for schooling.

TIMSS Advanced is an assessment for students in their final year of secondary school who are enrolled in special advanced mathematics and physics programsIt is the only international assessment that provides essential information about students' preparedness to enter university-level studies in science, technology, engineering, and mathematics (STEM). The study also collects policy-relevant data about curriculum emphasis, technology use, teacher preparation, training, and attitudes that can be used to guide education reform and policy planning in STEM fields

PIRLS, is one of the core studies of IEA, directed by the TIMSS and PIRLS International Study Center at Boston College. PIRLS is recognized as the global standard for assessing trends in reading achievement at the fourth grade.

PIRLS provides trends and international comparisons of fourth grade students’ reading achievement and students’ competencies in relation to goals and standards for reading education. In addition to reading assessment, the PIRLS school, teacher, student and home questionnaires gather extensive information about the contextual factors at home and school which are associated with the teaching and learning of reading.
