| Abstract: | 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. |
