AbstractThis study aimed to develop and validate a new objective measure of intra‐organizational career success, that is the Managerial Career Success Measure (MCSM). Although there has been a recent emphasis in the careers literature on the subjective career, there is still a need for a valid operationalization of ‘traditional’, objective career success as this construct is still considered relevant by many occupational and national groups; furthermore, many studies continue to use objective career success as a (dependent) variable. With regard to content validity, it appears that the measure that was developed incorporates some elements of the commonly used measures of objective career success (i.e. managerial level, number of promotions, salary and salary progression) while steering clear of some of the issues with each of them separately. Concurrent and discriminant validity were explored by analysing data from three empirical studies that were carried out in a large heterogeneous managerial population (N = 1101). Results indicate that the MCSM displays higher levels of content and construct validity than do other, commonly used measures of objective career success. Copyright © 2008 John Wiley & Sons, Ltd.
