摘　　要：项目反应理论下的计算机自适应考试能够根据应试者的实际能力水平选择相应难度的试题,做到因人施测,实现更快、更准地对应试者能力进行估计。对计算机自适应考试施测过程进行了描述,对模型的选择、选题策略、参数估计等关键技术进行研究并提出相应的解决方法,实现了系统的设计与开发。Computer adaptive testing based on the Item Response Theory can choose diffirent questions forexaminees according to their abilities and arrange different papers for different examinees, It can estimatethe examinees＇ abilities faster and more accurately. This paper describes the procedures of computerizedadaptive testing. Research were conducted and corresponding solutions were proposed about the model se-lection, item selection strategies, parameter estimation and other key technologies, making possible thedesign and development of the computerized adaptive testing system.
