摘　　要：测验等值是测验研究中相对薄弱的一个环节,许多重要的考试都尚未实现统计等值。造成这种窘境的原因,皆因等值操作困难化。在介绍测验等值概念及IRT测验等值优势的基础上,参考国内外关于测验等值的相关文献,构建出IRT测验等值的流程化操作思路,包括等值设计、数据收集、参数估计、量表化及测验等值5个步骤。以广东省佛山市中考考试为例,说明如何进行具体的测验等值流程化操作。Test equating is a relatively weak link for test research in psychological and educational measurement. There are many examinations that do not achieve the statistical equating. The reason is that it is may difficult for the people to do test equating if programmer of test equating does not he provided. Based on introducing the concept and merit of rtem Response Theory （IRT） test equating, the paper summaries some consideration about the programmer of IRT test equating, such as equating design, data collection, parameter estimation, scaling, test equating. This research exemplified high school entering examination of Foshan city in Guangdong province and explored how to do specific test equating design in accordance with the programmer of IRT test equating.
