摘　　要：等值作为保证测验公平性的技术手段,一直是测验理论研究的重要方面。MIRT理论的发展证明了题目和测验是复杂的,传统的单维模型已经不能满足对人和题目/测验之间关系的探讨需求。目前MIRT等值研究主要有两种取向,其中一种取向是研究多维数据对IRT等值会产生什么样的影响;第二种取向是通过开发新的计算方法和计算工具研究MIRT等值过程。MIRT等值研究最重要的是对等值方法和过程实现的研究,目前已取得一些进展,在进行这些研究的过程中最重要的考虑因素是控制其误差影响因素。As a technology to ensure the test equity, test equating is the important aspect of the test theory research. The development of MIRT proved the item and the test is complicated, the traditional unidimentional model have not been satisfied with the need of exploring the relationship of people and item/test. Now MIRT research have two tendency, one is to investigate how the multidimensional data have effect on the IRT equating, another is to study MIRT equating procedure by developing new calculating method and instrument. The key of MIRT equating research is to study the equating method and how to realize the procedure, which have some advances. In the process of these research, the most important factor is to consider fully how to control the error.
