In this paper, an overview of the observed-score equating (OSE) process is provided from the perspective of a unifying equating framework (von Davier in von Davier (Ed.), Statistical models for test equating, scaling, and linking, Springer, New York, pp. 1-17, 2011b). The framework includes all OSE approaches. Issues related to the test, common items, and sampling designs and their relationship to measurement and equating are discussed. Challenges to the equating process, model assumptions, and approaches to equating evaluation are also presented. The equating process is illustrated step-by-step with a real data example from a licensure test.
本文从一个统一的等值框架（冯·达维尔编著的《测验等值、量表编制及链接的统计模型》，施普林格出版社，纽约，第1 - 17页，2011b）的视角，对观察分数等值（OSE）过程进行了概述。该框架涵盖了所有OSE方法。文中讨论了与测验、共同题目、抽样设计相关的问题，以及它们与测量和等值的关系。还介绍了等值过程面临的挑战、模型假设以及等值评估方法。通过一个来自执照考试的真实数据示例，逐步展示了等值过程。
