How do managers in Not-For-Profit organizations conceptualize their career success? While the for-profit sector provides more objective measures such as salary level or position in the hierarchy, Not For Profit Organizations often lack hard and fast metrics. This work seeks to develop a theoretical model of how career success might be conceptualized. Based on social cognitive theory, the Cognitive Career Success Model (CCSM) attempts to explain the process of conceptualization through four loops: goal setting, attribution, equity evaluation and social comparison. While the CCSM is applicable to careers in all sectors and fields, this work looks in particular at specificities of the Not For Profit field. It examines different motivational make-up of managers in such organizations, particular personality traits, and special aspects of this career field.
