Many scholars believe that the legitimacy of governments depends on the quality of providing "public services". Public services are aim at providing public benefits, and if the government does not have the power to do this, it will lose its worth. The legitimacy of governments not only depends on the nature of the services they provide, but also on how they are presented. The purpose of this research is to assess the status of public services in three periods of public administration (pseudo-paradigms of public administration) and its excellence in the present era. Hence, while addressing the concepts of excellence, public services and the principles governing it, a brief overview of the three main stages of public administration, between the late decades of the nineteenth century and the beginning of the third millennium, namely the traditional public administration (TPA), new public management (NPM), and new public services (NPS) is also presented. In addition, the provision of public services has been investigated in each period and in the end, the importance of the excellent public services in the present age is raised.
