Maria Bolsinova wins prestigious prize for best dissertation

Cito graduate Maria Bolsinova was awarded the Psychometric Society Dissertation prize 2017 at the IMPS in Zurich, July 2017. This prestigious prize is awarded for the best psychometric dissertation in the world, and Bolsinova won it for her research on response times in educational measurement. 

Research on response times in computer tests


For her research ‘Balancing simple models and complex reality: Contributions to item response theory in educational measurement’ Maria analysed the potential correlation between children’s response times and  competences in answering questions in a computer test. She also developed a new method for reporting test scores, which provides an optimal reflection of competences. This method is an extension of the One Parameter Logistic Model (OPLM) that Cito uses to perform test and item analyses. All chapters of Bolsinova’s dissertation have already been published in prestigious journals including the British Journal of Mathematical and Statistical Psychology and Psychometrika.
