Program Chair (2023-2024)

Ben Shear is an Assistant Professor in the Research and Evaluation Methodology Program at the University of Colorado Boulder School of Education and a Faculty Partner of the Center for Assessment, Design, Research & Evaluation (CADRE). Ben earned his PhD in Education from Stanford University and an MA in Measurement, Evaluation and Research Methodology from UBC Vancouver. Ben’s research examines the development, interpretation, and use of educational assessments, with a focus on large-scale assessments. These efforts are aimed at supporting more appropriate and fairer uses of tests and assessments in education. To date this research has focused primarily on statistical and methodological issues related to the construction and analysis of standardized test scores, informed by issues arising at the intersection of education policy and psychometrics. One strand of this work has made contributions to the analysis of aggregate proficiency data and is integral to the construction of the Stanford Education Data Archive (SEDA), a publicly available national database created to study educational opportunity in the United States. A second strand of work has evaluated novel approaches for modeling student responses on tests and investigating the properties of statistical models used in state accountability systems. A third strand of work studies the ways test scores are used in educational policy and research. Ben teaches graduate courses in psychometrics and quantitative methods.
