Research Scientist

Dr. Schulz provides leadership on assessment development, psychometric issues, research studies, and other issues that may arise from program development, legislative actions, or stakeholder input. He supports high-stakes, customized assessments, and he guides continuous enhancement of processes in psychometrics, research methodology, applied statistics in assessment, reporting, and automated scoring. Dr. Schulz joined Pacific Metrics in 2007 as Lead Psychometrician for Louisiana’s on-line, end-of-course testing program. He became Director of Research in 2010, with additional responsibilities for research in automated scoring and data forensics, and operational data processing, item banking, and reporting.

Previously, as a Principal Research Statistician at ACT, Inc., Dr. Schulz developed techniques based on Item Response Theory (IRT) and domain scores for assigning students to achievement levels and for quantifying the consistency and accuracy of scores. Dr. Schulz also directed contracts with the U.S. Department of Education for setting achievement levels on the National Assessment of Educational Progress (NAEP), where he led the development of the Mapmark standard setting method and its adoption for setting NAEP achievement levels. As Director of Testing at the National Council of State Boards of Nursing, Dr. Schulz supervised research and development for transitioning the nursing licensure examination to a computer-adaptive format.

Dr. Schulz has published widely and serves as a consultant to state boards of education, school districts, and licensure and certification boards on topics of equating, vertical scaling, job analysis, and computerized testing.

Dr. Schulz has a Ph.D. in Special Field of Measurement, Evaluation and Statistical Analysis (MESA) from the University of Chicago.
