Dr. Jesper Tijmstra is an Assistant Professor in the Department of Methodology at the Tilburg School of Social and Behavioral Sciences, Tilburg University. His academic career includes previous positions as a test expert at Cito (2013-2014) and as a junior lecturer at Utrecht University (2011-2013), where he also completed his PhD in psychometrics.
Dr. Tijmstra's research focuses on advanced psychometric methods, particularly item response theory, testing theory, and measurement methodology. His work addresses critical issues in educational and psychological measurement including extreme response style, differential item functioning, response time analysis, and measurement invariance. His research bridges theoretical advances with practical applications in adaptive learning systems and survey methodology.
Analysis of his recent publications (2023-2025) reveals a strong focus on methodological innovations in psychometrics, particularly in detecting and correcting for response biases. His work frequently employs Bayesian approaches, simulation studies, and applications of IRT models to real-world measurement problems. The publications demonstrate both theoretical depth and practical relevance to educational and psychological assessment.
Dr. Tijmstra actively collaborates with a core group of researchers including Martijn Schoenmakers, Jeroen Vermunt, and Maria Bolsinova, with whom he has produced multiple high-impact publications. His work appears in top methodology journals such as Behavior Research Methods, Educational and Psychological Measurement, and Journal of Educational and Behavioral Statistics.
His research has practical implications for improving measurement quality in adaptive learning systems, cross-cultural surveys, and psychological assessments where response biases might threaten validity. His work on incorporating response times into ability tracking shows how methodological advances can enhance educational technology applications.
