IERI Autumn Academy 2018: Item Response Theory and Population Modeling in Large-scale Assessments

About IERI

IERI is a collaborative effort between the Research & Development Division at ETS and the IEA Data Processing and Research Center that focuses on improving the science of large-scale assessments. IERI undertakes activities around three broad areas of work that include research studies related to the development and implementation of large-scale assessments (research area); professional development and training (training area); and dissemination of research findings and information gathered through large-scale assessments (dissemination area).

IERI undertakes research activities that address issues surrounding large-scale assessments such as IEA-TIMSS, IEA-PIRLS, OECD-PISA, OECD-PIAAC, US-NAEP, IALS, ALL, etc. The label “virtual” is attached to the research area to emphasize that the research projects are hosted in the funding institutions, but are facilitated by Web-based collaboration as well as by the shared joint expertise of researchers involved in work on large-scale assessments. The aim of this virtual research area is to contribute to the science of large-scale assessments so that the best available information is provided to policy makers and researchers from around the world.

About the IERI Academies

The IERI Academies are biannual workshops sponsored by the IEA-ETS Research Institute. The Academies take place in May and November every year in different locations around the world. Locations are chosen based on proximity of potential attendees and interested host organizations.

Since 2007, IERI has conducted the Academies on topics such as the use of international large-scale assessment databases, item response theory and population modeling in large-scale assessments, use of hierarchical linear models in large-scale assessments, among others. A list of previous Academies can be found on our website: IERI Institute.
