How Reliable Are TOEFL Scores?
Wainer, Howard; Lukhele, Robert
Educational and Psychological Measurement, v57 n5 p741-58 Oct 1997
The reliability of scores from four forms of the Test of English as a Foreign Language (TOEFL) was estimated using a hybrid item response theory model. It was found that there was very little difference between overall reliability when the testlet items were assumed to be independent and when their dependence was modeled. (Author/SLD)
