Modern conditions of public administration are formed in the BANI world (Grabmeier, 2020), unstable, disturbing, uniquely technological and digital. How many of today's civil servants are capable of functioning in such a world through current training and professional development systems? This issue is particularly relevant for post-Soviet countries, as most of them belong to emerging economies that are still shaping their own unique public administration system. The article is aimed at studying the practice of professional development of civil servants within the framework of additional education in post-Soviet countries in the context of digitalisation. According to the study, it is clear that the Soviet model of supplementary education for civil servants is still valid, with minor differences in the countries studied. This model is characterised by a centralised organisation of training of civil servants within the framework of specially created structures (public service academies). With the transition to digital learning, countries are differentiated by the pace and level of transition to distance and e-learning for public servants.
