The improvement of teacher competencies in medical education belongs to a wider system of professional development of employees, also known as faculty development. Faculty development is a focused strategy of a higher education institution for enabling the acquirement of knowledge, skills and attitudes in its fundamental activities, including education, research methodology and leadership. Organized strategies, especially for the conduction of different types of education and various professional activities, are particularly important and developed in the health professions, and are conducted through separate organizational units, such as offices, centers or departments. In modern medical education, it is crucial that each higher education institution has a centralized strategy for managing the faculty educational development of teachers, which should be aligned with the vision and mission of the faculty, especially the teaching and quality control sectors.
