In Belgium, assessment centers have grown in popularity. Despite this growing popularity, the validity of these selection and development methods has not been examined in Belgium. Therefore, this study examines the predictive validity and fairness of an assessment center of a large bank. The sample consisted of 252 middle level managers. Results revealed that the assessment center provides a valid prediction of success in higher managerial positions. With respect to fairness, this assessment center also scores well. Virtually no significant differences between men and women and between Flemish and French speaking Belgians are found. These positive results might be explained by the high-quality design of this assessment center. (c) 2005 Association internationale de psychologie du travail de langue francaise.
