About IEA

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.

IEA Studies

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. Our ICCS and ICILS studies are directed by the Australian Council for Educational Research. IEA is grateful for the expert guidance of our study centers.
