Abstract

Existing studies manipulated DIF under the CDM framework as having different slip and/or guessing parameters, but an identical Q-matrix, across groups of examinees. This study clarifies such a fallacy on DIF manipulation and proposes a new method for DIF assessment. Simulation results reveal the superiority of the new method.
