Test Security Methods in Computerized Adaptive Testing
计算机自适应测验中测验安全控制方法评述

Computerized adaptive testing has been subject to security problem in practice.To solve the problem,the researchers at home and abroad have done a lot mainly in two ways.One is to impose a maximum exposure rate of items in the bank that no item could exceed,which includes SH method,item eligibility method,multiple maximum exposure rate method and so on.The other is to improve item selection strategy,which involves a-stratification method and its alternations.Furthermore,the two solutions have been integrate...
