Robert Mislevy holds the Frederic M. Lord Chair in Measurement and Statistics at Educational Testing Service. He was previously at the University of Maryland as a Professor of Measurement, Statistics, and Evaluation (EDMS). He was also an Affiliate Professor of Second Language Acquisition and the Joint Program in Survey Methods. He was previously a Distinguished Research Scientist at ETS and a Research Associate at National Opinion Research Center. He earned his Ph.D. in Methodology of Behavioral Research at the University of Chicago in 1981. Dr. Mislevy’s research interests center on applying recent developments in statistical methodology and cognitive research to practical problems in educational and psychological measurement. His work has included a multiple-imputation approach for integrating sampling and test-theoretic models in the National Assessment of Educational Progress (NAEP), a Bayesian inference network for updating the student model in an intelligent tutoring system, and a demonstration of a framework for monitoring and improving portfolio assessment evaluation (in the context of the Advanced Placement Studio Art Portfolio assessment). His current projects include the NSF-supported PADI project, which is developing an assessment design system with a focus on science inquiry, and work with the Cisco Learning Institute and Educational Testing Service on simulation-based assessments of design and troubleshooting of computer networks. Among his honors and awards are the American Educational Research Association’s Raymond B. Cattell Early Career Award for Programmatic Research, the National Council of Measurement in Education’s Award for Technical Contributions to Educational Measurement (three times), the ETS Senior Research Scientist Award, AERA’s Lindquist Award and the International Language Testing Association’s Samuel J. Messick Memorial Lecture Award. In 1992, he was elected president of the Psychometric Society. In 2003, he was presented the National Council of Measurement’s Award for Career Contributions to Educational Measurement. He has served several committees of the National Research Council on issues concerning assessment, instruction, and cognitive psychology, and was a primary author of final report of the National Assessment Governing Board’s Design Feasibility Team.
