Introduction. In the digital age, a primary condition for ensuring national security, fostering long-term economic development, and enhancing the quality of life for citizens is the effective functioning of state civil service institutions. Consequently, the quality of training for future employees in public authorities, particularly in the field of information and communication technologies, is of paramount importance.Aim. The present research aims to establish scientific and methodological foundations for a differentiated approach to developing digital competencies among future specialists in public and municipal administration during their training.Methodology and research methods. The methodological foundation of the study was grounded in the methods and principles of systems analysis, as well as general logical methods of scientific inquiry, including analysis, synthesis, generalisation, induction, and deduction. Additionally, it employed modelling techniques such as mental modelling and visual modelling.Results. The definition of the category “differentiation” as a specific form of educational organisation has been established. Key principles have been identified and substantiated, including the principles of complexity levels, individualisation, and collaboration. A framework model for the differentiated training of future public authority employees in the field of digital technologies has been outlined.Scientific novelty. A new methodology for training future specialists in state and municipal administration has been developed, substantiated, and is currently being implemented, taking into account contemporary trends in the evolution of the higher education system, particularly in the realm of digital technologies.Practical significance. The results obtained can serve as a methodology for organising educational activities within the higher education system, specifically for training future employees of public authorities.
