IEA Studies

We conduct high-quality, large-scale comparative studies of education across the globe 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 Boston College's Lynch School of Education and Human Development. Our ICCS study is directed by IEA's ICCS International Study Center at the University of Bath's Department of Education. The latest cycle of ICILS is directed by IEA's ICILS International Study Center at IEA.  Previously, both ICILS and ICCS were directed by the Australian Council for Educational Research. IEA is grateful for the expert guidance of our study centers.
