Our Cooperation


The IEA-ETS Research Institute (IERI) is a collaboration between the Research and Development Division at ETS and the IEA that focuses on improving the science of large-scale assessments. The aim of the institute is to provide policymakers and researchers from around the globe with the best available information in the field. In line with that purpose, IERI undertakes activities relating to three broad areas of work: research, training, and dissemination of research findings.

The IERI journal

Large-Scale Assessments in Education is a joint publication of the International Association for the Evaluation of Educational Achievement (IEA) and Educational Testing Service (ETS). The articles in this journal contribute to the science of large-scale assessments, help disseminate state-of-the-art information about empirical research using these databases and make the results available to policymakers and researchers around the world.

IERI academies

IERI’s work is crystallized as workshops called the IERI academies. These events take place twice a year, in May and November, in different locations around the world. Some of the topics discussed in previous IERI academies include international large-scale assessment databases; item response theory and population modeling in large-scale assessments; and use of hierarchical linear models in large-scale assessments.

Training offered by RandA

Our Research and Analysis Unit (RandA) also offers researchers a number of training sessions and workshops throughout the year across different locations. To learn more about this service, please visit our training section.

Our academic visitor program

The IEA welcomes academic visitors who wish to benefit from IEA Hamburg's vibrant research culture, and gain experience with IEA's international research activities. The program exists to build links and encourage collaboration with other research organizations around the world, enabling academics and practitioners the opportunity to work together on joint research projects, and exchange ideas and expertise with our own resident research staff. This is an opportunity to work closely with IEA researchers in our Hamburg office, who will endeavor to provide support and help develop your own research goals.
