关 键 词：Multifaceted Rasch model Grouping assessment Item Characteristic function Score correction
摘 要：In the event of large-scale competitions, various factors such as the criterion of judges, the characteristic level of competitors and the testing mechanism affect the assessments on the practical capacity of competitors, making an unfair result. This paper introduces a Multifaceted Rasch Model which is based on Item Characteristic function. From the aspects of judges, competitors and testing mechanism, Facets Statistics Software is used in this model to analyze the consistency and deviation of the competitors’ scores, so that the three aspects can fall into the same evaluation scale. According to empirical analysis, to introduce an intermediate value as a parameter based on the model to further comprehensively correct the scores can obtain a good fitting result, which to some extent reduces the error of the assessment results brought by the subjective factors from the judges from different groups, and improves the fairness of the competition, providing a new way for the competition assessment.
