Performance on psychological tests and personality inventories may be unexpected. This may be due to cheating or test anxiety (achievement testing), or response inconsistency or lack of traitedness (personality). Traditional person-fit measures are primitive in that they only flag unexpected performance but do not provide explanatory information. Two recent approaches provide more explanatory information. One is flexible (i.e., nonparametric) but only suggests an explanation. The other is not as flexible (i.e., parametric) but explicitly uses auxiliary information in a multilevel framework. Both approaches are studied and integrated so as to provide a better understanding of individual test performance.
