Patrick Meyer, PhD
Vice President of Psychometrics and Analytics
Patrick Meyer manages the team of psychometricians, statistical analysts, and project managers involved in the district division of NWEA. This team conducts psychometric research for assessments such as MAP Growth and MAP Reading Fluency. His research interests include IRT, psychometric software design, and the psychometric characteristics of teaching measures. Dr. Meyer is the inventor and lead developer of jMetrik, an open-source software program used in over 20 countries. He has authored two books and published over 20 articles in peer-reviewed journals such as the Journal of Educational Measurement, Applied Psychological Measurement, and Educational and Psychological Measurement. He has conducted 25 standard-setting workshops in the licensure and certification field, as well as numerous workshops on psychometric theory and the use of jMetrik for data analysis. Prior to joining NWEA in 2018, Dr. Meyer worked as an associate professor with tenure in the Curry School of Education at the University of Virginia, where he taught courses in educational measurement and applied statistics. He began his academic career in 2004 as an assistant professor at James Madison University’s Center for Assessment and Research Studies. Dr. Meyer holds a PhD in educational psychology and research from the University of South Carolina.
