The Buros Center for Testing, in collaboration with Educational Testing Service (ETS), is hosting the 12th annual Buros/ETS lecture on Monday, October 29 at 2:15 p.m. The event is free and open to the public and will be held at the University of Nebraska-Lincoln, Teachers College Hall, room 112, followed immediately by a reception in the Buros Library.
The annual lecture series brings a distinguished researcher from Educational Testing Service to the UNL campus to speak on current assessment and testing issues. This year, Dr. Jonathan Weeks will give a presentation titled "Issues in Multidimensional Test Linking.”
Dr. Weeks will provide a foundation for understanding multidimensional test score linking and various issues that should be considered in this process, including value-added sub-scores, the number of common items, the linking design, and the choice of linking method. These issues will be discussed in the context of an empirical measure of foundational reading skills and the development of a multidimensional vertical scale.
Jonathan Weeks is Associate Research Scientist of Global Assessment at Educational Testing Service (ETS). His work focuses on multiple forms of test linking, equating, and scaling. Dr. Weeks has been awarded several major grants, forging the way as lead psychometrician on an especially large project with the Institute of Education Sciences, Reading and Writing. He is the creator of a popular R package (plink) for linking mixed-format tests using IRT-based methods.
