Many scholars have suggested that public service motivation (PSM) is a defining characteristic of public and non-profit employees. However, interest and motivation alone are not the sole determinates of success in any organization. Employees must also possess the knowledge and skills that will help them accomplish the difficult tasks that arise in their chosen occupation. This study explored the relationship that PSM has to student satisfaction in MPA programs, taking into consideration program climate and number of years of government experience. The findings confirmed that while PSM is related to student satisfaction, this relationship was completely mediated by program climate. The implications of the study are discussed, in particular in terms of the contributions that an environment of support and PSM make on the attitudes of students in MPA programs.
