Traditional methods for detecting cheating on assessments tend to focus on either identifying cheaters or compromised items in isolation, overlooking their interconnection. In this study, we present a novel biclustering approach that simultaneously detects both cheaters and compromised items by identifying coherent subgroups of examinees and items…

Proposed two new indices to detect answer copying on a multiple choice test and conducted a simulation study to investigate the usefulness of both indexes. Discusses conditions under which the proposed indexes can be useful. (SLD)

This study examines a score-difference model for the detection of cheating based on the difference between two scores for an examinee: one based on the appropriate scoring key and another based on an alternative, inappropriate key. It argues that the score-difference method could falsely accuse students as cheaters. (Author/JAZ)
