Assessment Centres within the South African Workplace: Relationship between a Situational Judgement Test and Ability and Personality Measures.This research investigates the relationship of a specific situational judgement test, Scenarios, to that of ability and personality measures through a discriminant validation study. The Scenarios Test was developed in order to assess the construct of Managerial Judgement within the work context. Despite the fact that this instrument has demonstrated reliability and validity evidence, this has been primarily obtained within a European context. Therefore, this study will contribute towards the growing body of evidence supporting the psychometric integrity of the use of Scenarios within a South African context. Moreover, this research aims to determine whether or not a situational judgement test of Managerial Judgement provides information relating to constructs which are not sufficiently measured by ability tests and personality questionnaires. The results indicate that there is significant inter-correlation between the scales of Scenarios, but not between Scenarios and the other instruments used (cognitive ability tests and a trait personality measure). This may support the hypothesis that SJTs could measure a broader underlying construct, such as tacit knowledge, as well as the fact that they may provide unique information relating to candidates‟ potential job performance which is not provided by tests of ability and personality.
