Jonathan Weeks, associate research scientist of global assessment at Educational Testing Service and creator of a popular R package for researchers, will present this year’s Buros/ETS lecture at 2:15 p.m. Oct. 29 in Teachers College Hall, Room 112. The talk, “Issues in Multidimensional Test Linking,” is free and open to the public.
The annual lecture series, now in its 12th year, is a joint effort by the Buros Center for Testing and Educational Testing Service that brings distinguished researchers from ETS to campus to speak on current assessment and testing issues.
Weeks will provide a foundation for understanding multidimensional test score linking and various issues that should be considered in the process, including value-added sub-scores, number of common items, linking design, and 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.
Week’s work focuses on multiple forms of test linking, including equating and scaling. He 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.
A reception in the Buros Library will follow the lecture. For more details, please see the Buros Center for Testing website.
