Iowa City, home to the University of Iowa (UI), Pearson and ACT, is an influential hub for psychometric research, particularly with respect to psychometrics supporting assessment. The UI has a long and rich tradition of being at the forefront in the development of assessment principles and supporting assessment research, and houses both the Center for Advanced Studies in Measurement and Assessment (CASMA), and Iowa Testing Programs. Similarly, both ACT and Pearson are recognized as global leaders in testing and assessment, with products and tests that are firmly grounded in research and supported by empirical studies. Continuing that tradition, ACT recently added a new unit, ACTNext, further enhancing its expertise in psychometric research and technology.

The goal of this summit is to emphasize the power of the local scientific community and to underscore Iowa City’s continued development as a research hub for psychometrics in assessments. The summit focus is on test comparability, including equating and linking, as test comparability is one of the core activities in educational assessment and an area where the local psychometric community excels.

Speakers include experts from the Iowa City community and beyond.
