The author notes that Ukraine's desire to integrate into the European educational space necessitates a detailed analysis and systematization of the experience of foreign countries in the professional development of research and pedagogical staff in the system of postgraduate education. The consideration of advanced training and the development of professional competencies of pedagogical and research-pedagogical workers on the experience of neighbouring Poland is actualized. Based on the scientific research of domestic and Polish scientists, the author, taking into account the distribution of professional competencies of academic teachers into four groups: scientific and professional, psychological and pedagogical, managerial and digital, analyses the Polish experience in the development of academic teachers. Theoretically, it states that Polish universities provide their professional staff with a variety of opportunities for professional growth, providing the most effective and favourable conditions for their further professional development. It also notes the importance of developing professional reflection, a creative approach to one's profession, studying and analysing not only one's own pedagogical professional activities, but also one's own educational ones. The author analyses the activities of a number of Higher Educational Establishments on the professional development of academic teachers, these are: the University of Warsaw, Andrzej Frycz Modrzewski Krakow University, Pomeranian University in Slupsk, Social Academy of Sciences. Vivid examples of their activities in the development of academic workers are provided. The author comes to the conclusion that the professional development of academic teachers in Poland today takes place with the help of a variety of tools. It should be noted that the measures taken by the neighbouring country almost coincide with the work to improve the qualifications of research and pedagogical staff in modern Ukraine, however, they are implemented at a higher quality level; teachers are presented with more opportunities to improve their professional activities, Poland attracts more international specialists for the education of its specialists. Programs and grants that contribute to the scientific, research-related and, in general, professional development of education specialists are implemented. In general, in the context of globalization and European integration of educational processes, the exchange of educational experience is necessary to provide high-quality educational services.
