Bernard Veldkamp specializes in research methodology and data analytics. His interests focus on optimization, text mining, and computer-based assessment. His work spans a range of issues in educational, psychological, and health sciences, from the development of new methods/models for the design and construction of (adaptive) psychological and educational tests, to the development of data mining models for analyzing verbal data and large datasets in fraud detection. He founds his research in Psychometrics, Operations Research, Data Mining, and Statistics.
Bernard Veldkamp is head of department Research Methodology, Measurement and Data Analysis. He is scientific director of the Research Center for Examination and Certification (RCEC), a cooperation of CITO, the national institute for measurement in the Netherlands and the University of Twente. Bernard Veldkamp recently spent a year at Law School Admission Council in Newtown, Pennsylvania, where he worked on robustness of test assembly methods and on the combination of data mining and IRT models to increase measurement precision.
