本章讨论 ETS 开发的使用差异项目功能 (DIF) 统计数据的程序，而不是统计数据本身。为了确定 ETS 使用 DIF 的起源，我首先解释黄金法则保险公司和解及其影响。然后我非常简要地描述了 20 世纪 60 年代末到 80 年代中期 ETS 使用的 DIF 的前身。正如那些了解 ETS 的人所预料的那样，有关使用 DIF 的决定是由一个委员会做出的。我描述了该委员会的成员和职责。
The chapter deals with the procedures that ETS developed to use the differential item functioning (DIF) statistic, not the statistic itself. To establish the context for the origins of the use of DIF at ETS, I first explain the Golden Rule Insurance Company settlement and its effects. Then I very briefly describe the precursors of DIF in use at ETS from the late 1960s to the mid 1980s. As those who know ETS might expect, decisions about the use of DIF were made by a committee. I describe the members and responsibilities of that committee.
