He is the author of two books: Invariant measurement with raters and rating scales: Rasch models for rater-mediated assessments (2018 with Dr. Stefanie A. Wind) and Invariant measurement: Using Rasch models in the social, behavioral, and health sciences (2013) He is the co-editor of five books, and he has authored or co-authored over 200 journal articles, book chapters, and monographs. Professor Engelhard was a co-editor of the Journal of Educational Measurement. He serves on several national technical advisory committees on educational measurement and policy in several states in the United States. In 2015, he received the first Qiyas Award for Excellence in International Educational Assessment recognizing his contributions to the improvement of educational measurement at the local, national and international levels. He is a fellow of the American Educational Research Association. 

Jue Wang, Ph.D. is an assistant professor in Research, Measurement & Evaluation Program at The University of Miami. Dr. Wang received her Ph.D. in Quantitative Methodology (QM) Program under Educational Psychology at The University of Georgia (UGA) in 2018. She also obtained a M.S. degree in Statistics at UGA. While at UGA, Dr. Wang was awarded the Owen Scott Doctoral Research Scholarship in 2016 recognizing the contribution of her research work on evaluating rater accuracy and perception using Rasch measurement theory. Furthermore, she received the QM Outstanding Student Award in 2018 recognizing her accomplishments in research, teaching, and service during graduate school. Her research focuses on examining rating quality and exploring rater perception in rater-mediated assessments using measurement models, such as a family of Rasch models, unfolding models, and multilevel item response models. She has published in major journals related to measurement including Educational and Psychological Measurement, Journal of Educational Measurement, Assessing Writing, and Psychological Test and Assessment Modeling.
