The dynamics and complexity of modern administrative environment, marked with extensive and rapid technological, social, economic and geopolitical changes, continually actualises old and imposes a new set of issues and challenges. A difficult adjustment to emerging circumstances, as a rule, is typical for administrative organisations and administrative systems as a whole. Intensifying the evolution of macro, mezzo and micro administrative system levels, towards more flexible and innovative structures during the 21. century, thus presents an imperative.There is a special focus on the redefining of roles of public servants; traditional and managerial understanding of service has been replaced or upgraded with a set of new requirements of a modern understanding of public service. Continuous learning and development of competencies for public servants is thus emphasized, especially in administrative systems characterized by obsolete and bureaucratic working methods. Education for public service, as an inter-organizational method of training and development of current and future public servants is the focus ovog this research, due to its integrity. At the same time, the author examines the basic orientation of the structure of course programmes and the developmental course of education for public administration in the Republic of Croatia. The author confirms the dominant legal orientation of education for public administration, as well as the existence of statistically significant changes in the system of administrative education towards interdisciplinarity, for the period from 2013. to 2022. Compliance with the existing convergence trends, especially with those related to the preferred university education, as well as modernization, enrichment and diversification of courses with a strong progression of relevant knowledge and skills in the areas of IT science, statistics, sociology, politology, psychology, and possibly artificial intelligence, is deemed necessary.
