IEA (International Association for the Evaluation of Educational Achievement) is an international cooperative of national research institutions, governmental research agencies, scholars, and analysts working to research, understand, and improve education worldwide.
We conduct high-quality, large-scale comparative studies of education across the globe in order to provide educators, policymakers, and parents with insights into how students perform.
Since their inception, our flagship TIMSS & PIRLS studies have been directed by the TIMSS & PIRLS International Study Center at the Lynch School of Education in Boston College. Previously both were directed by the Australian Council for Educational Research, the latest cycle of ICILS is directed by IEA, and the upcoming cycle of ICCS will be directed by the University of Bath.IEA is grateful for the expert guidance of our study centers.
