Abstract
Situational judgment tests (SJTs) pose unique cognitive demands on test takers in that, when presented in written form, they require a great deal of reading and cognitive effort. Test takers are likely to become fatigued after repetitive responding to SJT items. This fatigue effect threatens the validity of SJT scores and potentially leads to inaccurate measurement. The fatigue effect was investigated at the item-level with two test forms consisting of the same items presented in reversed order. Data were obtained from 1,089 applicants to an hourly job for a large international corporation. Results showed that items toward the end of the test exhibited the greatest fatigue effect in that they were more difficult and elicited more omitted responses.
