Purpose: The purpose of this paper is to investigate continuing pedagogical education from a new perspective that is especially relevant during the development of an information society. Design/methodology/approach: The methodological framework of the study builds on the concept of teacher's personality establishment in the system of pedagogical education. Main stages of professional development were studied on the basis of educational institutions of the Baikal region. Thus, experiments were conducted at the Pedagogical Institute, Buryat State University Continuing Education Institute, Buryat Republic Institute of Educational Policy and the Buryat Republic Pedagogical College. The study used internship platforms of the above educational institutions. Findings: The study shows how the open online pedagogical space, which includes internship and innovative platforms, specialized departments, governing agencies on education, certificate centers, scientific and cultural institutions, higher educational institutions, and schools, reveals the model of continuing pedagogical education in regions. Practical implications: Individual forms of advanced training are proposed. Optimal ways to create a competitive environment in the system of professional development were identified by the authors. Originality/value: The reformation of the regional system of advanced training and its transition to a new level of quality allows organizing continuing improvement of teachers' professional competencies effectively. This paper can improve the professional competence of teachers, which will have a positive effect on the educational process and academic performance of students in general. The next stage in the improvement of teachers' competence can involve an exchange of experience at international conferences and participation in joint international educational programs.
