Current geopolitical situation and Russia's withdrawal from the Bologna process showed the urgent need to improve the national system of continuous pedagogical education, in which the master's program as the second level of higher education is focused on more in-depth, in comparison with the bachelor's degree, professional training of graduates, providing them with a high level of professional identity as the most important indicator of professional development. Due to a number of reasons (changes in master's degree standards, increased requirements for graduates with short terms of study and the lack of basic specialized education for many students, etc.), the quality of education in the master's program has significantly decreased, manifested in the absence of an increase in the educational level of students. Currently, to ensure the quality of teacher training in master’s studies, universities should find reserves in the organization of the learning process to develop professionalism among students, develop and implement flexible modular educational programs, their technological support, and build an effective system of interaction with employers. The purpose of the study: to develop a model for the formation of professional identity of students of pedagogical magistracy in the conditions of a system-modular organization of the educational process. The theoretical methods were an analytical review of scientific sources on the problem of professional identity, analysis and generalization of the results; pedagogical modeling. Based on the results of the theoretical analysis, the structural-content components of the professional identity of teachers are revealed as a complex, integrative, dynamic personal education that influences the professional development and success of the professional pedagogical activity. The method of pedagogical modeling led to the creation of a model for the formation of professional identity among master’s degree students in pedagogy with a system-modular organization of the educational process. The model makes it possible to form ideas about the formation of students' professional identity during the period of study in a pedagogical master's program as a systemic, dynamic, cyclical process of subject-subject pedagogical interaction between participants in educational relations.
