Lisa A. Keller earned her BS in mathematics from St. Michael's College in 1993, and her MS in mathematics from the University of Massachusetts Amherst in 2001. She received her doctorate from the University of Massachusetts Amherst in Psychometric Methods in 2002. She has fifteen years' experience in the field of psychometrics. Her research interests have focused primarily on item response theory equating and scaling, reliability, and measuring student growth. She has published several articles and presented her research at national and international conferences. Dr. Keller is a member of the National Council of Measurement in Education, American Educational Research Association, the American Statistical Association and the Psychometric Society. In addition to her psychometric experience, Dr. Keller has taught mathematics to grades 7-12. Robert Keller has spent ten years as an operational psychometrician in K-12 education. His primary duties in that role included performing most of the test scaling and equating for large-scale state-wide assessments for purposes of No Child Left Behind accountability systems. In addition to this, Dr. Keller was the product owner of the computer adaptive testing engine being developed for the next generation test delivery system that was simultaneously under development, as well as systems to automate, streamline, and manage data for analyzing large scale testing programs. In addition to these tasks, he has been actively engaged in research, published in peer reviewed journals, presented at national conferences, and in support of high stakes testing contracts, in the areas of scaling, equating, computer adaptive testing, and growth modeling. Dr. Keller is a member of the National Council of Measurement in Education, American Educational Research Association, and the Psychometric Society. He serves as a peer reviewer for several journals including the Journal of Educational Measurement, Applied Psychological Measurement, and the International Journal of Testing. Michael Nering has over 20 years of professional psychometric experience. His research interests include person fit, item response theory, computer-based testing, and equating. He has presented and published numerous articles on a wide range of psychometric topics, and he is actively involved in the research community in various capacities. Dr. Nering is a member of the National Council of Measurement in Education, American Educational Research Association, American Psychological Association, and the Psychometric Society. For the AERA 2005 conference he was a program chair for Division D – Measurement and Research Methodology. He has also served as treasurer of the Psychometric Society, and hosted the 2008 International Meeting of the Psychometric Society. In addition, Dr. Nering has served as reviewer for several peer journals, including the Journal of Educational Measurement, Applied Psychological Measurement, Psychometrika, and the Journal of Experimental Education. In 2013 Dr. Nering was co-editor to the International Journal of Testing sponsored by the International Test Commission.
