The Item Response Warehouse (IRW): A Large Open Repository of Response Data

• In Event: Surveys of/for the Measurement Community

Abstract

In contrast with other disciplines, psychometrics has limited public data. The IRW is designed to change that through the collection and standardization of a large volume of item response datasets. We describe key elements of the data standardization process and the nearly 1 billion item responses already in the IRW.
