The International Association for the Evaluation of Educational Achievement (IAEAA) is a global organization focused on assessing and improving educational quality. Established in 1958, it conducts large-scale studies to evaluate student performance across different countries. These assessments help policymakers understand educational outcomes and identify areas for improvement. IAEAA is best known for its flagship studies, such as the Trends in International Mathematics and Science Study (TIMSS) and the Progress in International Reading Literacy Study (PIRLS). These studies provide valuable data on how students perform in subjects like mathematics, science, and reading, enabling countries to compare their educational systems.
