Naidan Tu, Ph.D.

Assistant Professor
422 Bluemont Hall
Background and Research Interests
Dr. Tu’s research focuses on the development, application, and evaluation of psychometric methods to improve noncognitive assessments used in organizational and educational contexts. Her work aims to improve the effectiveness of personnel selection and educational admissions where assessment scores are used to inform high-stakes decisions about people. Her primary research areas include response bias prevention and detection, forced choice measurement, item response theory, computerized adaptive testing, and emerging technologies in assessment. Her work has been published in leading peer-reviewed journals such as Organizational Research Methods, Behavior Research Methods, and Applied Psychological Measurement. She also develops R packages, including bmggum, fcirt, and fcscoring, to make these methods accessible to the broader research and practice community.

Ongoing and Upcoming Future Projects
Examples of ongoing and upcoming future projects focus on (1) constructing and scoring forced choice tests, (2) detecting aberrant responding, such as faking, random responding, or AI-generated responses in personality assessments, and (3) improving assessment efficiency in organizational and educational settings using collateral information.
