The present research examines differential item functioning (DIF) of an ESL placement exam for the examinees with different academic disciplines using two DIF detection methods: the Mantel-Haenszel(MH) and logistic regression procedures. Findings indicated that no item showed large DIF in the MH procedure but one item showed uniform DIF and two items showed non-uniform DIF in the logistic regression procedure. The items flagged for DIF were not considered biased against students with particular academic backgrounds, however. The content expert panels shared the idea that the language in those items is not only domain specific but also part of general academic vocabulary that college students should know. In other words, knowledge of the language in the items flagged for DIF can be considered to be part of the construct being measured in the test. Consequently, it was judged that the difference in difficulty between the two groups of those items was attributed to a legitimate reading ability difference. Finally, validity of the ESLPE score interpretation, decision and consequences was also discussed.
