LIU Fa-ming~(1,2),DING Shu-liang~1(1.JiangXi Normal University,Computer Information Engineering College,Nanchang 330027,China;2.GanNan Normal College,Department of Mathematics and Computer,Ganzhou Jiangxi 341000,China)  
Computerized adaptive testing is an important direction of examination reform.The latent trait vector estimation and item selection in MAT are discussed in this paper.An algorithm of item selection for MAT is proposed.This algorithm changes computing max|A+xx′| into max[WTHX](x′A~(-1)x) when A is known and the domain of x is known.
