ABSTRACT

A commentary on the articles presented in this issue is provided that focuses on a practitioner’s perspective on equating and linking with small samples. A review of each article’s design and outcomes is followed by the practical implications when implementing the researched study elements and the guidance offered by the authors. Inter-relationships among the variables of interest presented in the articles (measurement model, equating procedure, anchor item selection, item parameter drift, and data collection/retention processes) are examined and some attempts at prioritization are provided. Key take-aways are offered, which include a careful approach to anchor item selection and form assembly, usage of empirical data over SME judgments when determining equivalence, and thoughtful consideration of the many permutations of design decisions prior to implementation.

摘要

提供了对本期文章的评论，重点是从业人员对小样本的等同和链接的观点。在实施所研究的研究要素和作者提供的指导时，对每篇文章的设计和结果进行回顾，然后给出实际含义。检查了文章中所关注的变量之间的相互关系（测量模型，均衡过程，锚点项目选择，项目参数漂移和数据收集/保留过程），并提供了一些进行优先级排序的尝试。提供了一些关键要点，其中包括谨慎的方法来锚定项目选择和表单组装，确定等效性时使用经验数据而非SME判断，
