Audrey Leroux is an associate professor of research, measurement and statistics in the Department of Educational Policy Studies at Georgia State University. She earned her B.S. in mathematics and Ph.D. in educational psychology specializing in quantitative methods from The University of Texas at Austin. She teaches graduate courses in introductory and advanced multilevel modeling, R programming, regression analysis, survey research and introduction to quantitative methods. Her methodological research evaluates innovative models and their applications in both multilevel modeling and computerized adaptive testing.
Specifically, her multilevel modeling research examines the effects of different multilevel models for handling complex data structures such as individual mobility across clusters, particularly with longitudinal data. Her research in multilevel modeling has appeared in Multivariate Behavioral Research, The Journal of Experimental Education, Educational Assessment, Evaluation and Accountability, and Methodology: European Journal of Research Methods for the Behavioral and Social Sciences.
Her computerized adaptive testing publications concentrate on novel procedures within item exposure controls and stopping rules, and have been published in journals such as The Journal of Experimental Education, Educational and Psychological Measurement, Applied Psychological Measurement, and Journal of Applied Measurement.
