FACTORS WHICH IMPROVE THE CONSTRUCT-VALIDITY OF ASSESSMENT-CENTERS - A REVIEW

This article reviews 21 studies which manipulated specific variables t o determine their impact on the construct validity of assessment cente rs. This review shows that the studies regarding the impact of differe nt observation, evaluation, and integration procedures yielded mixed r esults. Conversely, dimension factors (number, conceptual distinctiven ess, and transparency), assessor factors (type of assessor and type of assessor training), and exercise factors (exercise form and use of ro le-players) were found to moderate construct validity. On the basis of the review, practical recommendations are derived to maximize the pro bability that practitioners design and administer an assessment center with construct validity. Finally, new perspectives for future researc h are identified.
