摘　　要：培养合格的飞行员无论对航空公司还是对乘客都至关重要。为了符合航空法规要求和飞行安全,航空公司要定期对所有飞行员进行培训及评测。研究如何通过测试更好地评价飞行员、测评分数,明确能够真实客观反映飞行员水平的能力指标,对航空公司及培训机构都有重大意义。在基于项目反应理论(Item Response Theory,简称IRT)的Rasch数学模型的基础上,通过分析计算试题的难度与质量、试题的鉴别度、人的分数能力等重要参数,建立一套自适应的理论测评方法,进而自动判断试卷的可靠性,同时用真实的测评数据进行回归分析,从而建立一套独特的自适应测评管理方法。在全球范围内首次提出飞行员胜任力三层理论这个重要概念,为飞行员能力评价及试卷可靠性评价提供了可行的实施方案和重要理论依据。It is very important for airlines and passengers to train qualified pilots.In order to meet the requirements of aviation laws and regulations and flight safety, airlines are required to train and evaluate all pilots regularly. It is of great significance for airlines and training centers to study how to better evaluate pilots through tests, and which indicators can more truly and objectively reflect the level of pilots: flight skills of pilots or their evaluation scores. Based on the Rasch model of IRT theory, this paper establishes a set of adaptive theoretical evaluation methods by analyzing and deriving important parameters such as the difficulty and quality of test questions, the discrimination index of test questions, and the pilot ability, etc., and then automatically judges the reliability of an exam. At the same time, the regression analysis was carried out with real airline data, so as to establish a set of unique self-adaptive evaluation management methods. And the important concept of Three-Tier of Core Competency was put forward for the first time in the world, which provides a feasible implementation a feasible and valuable theoretical basis for pilot skill evaluation and test reliability assessment.
