摘要

当每个暴露的项目都有漂移的危险时，检测项目参数漂移的方法可能是不够的。为了解决这种情况，提出了一种检测项目参数漂移的策略，该策略仅使用实验设计中分层随机方法部署的未暴露项目。通过调查高风险执照考试中意外的分数增长来说明所提出的方法。本例的结果提示项目参数漂移，但在0.05水平上不显著。

An Experimental Design to Investigate Item Parameter Drift.

Methods for detecting item parameter drift may be inadequate when every exposed item is at risk for drift. To address this scenario, a strategy for detecting item parameter drift is proposed that uses only unexposed items deployed in a stratified random method within an experimental design. The proposed method is illustrated by investigating unexpected score increases on a high-stakes licensure exam. Results for this example were suggestive of item parameter drift but not significant at the .05 level.
