The article is devoted to the study of real and prospective practice of mentoring. The information base was data from the questionnaire survey of the personnel of Moscow medical organizations, carried out in 2019. The scale and character of the involvement of medical personnel in the mentoring system were studied with regards to prospective and appropriate models. The need for introduction or expansion of mentoring was compared with the available personnel potential. It turned out that doctors and nurses are involved in various types of mentoring. These are additional training in the workplace, regulated by the management, initiative assistance to youth during their adaptation, and various forms of informal transfer of practical knowledge on a wide range of issues. The demand for mentoring turned out to be higher among doctors and in hospitals. A comparison of respondents who had a mentor and who did not had one, but needed, revealed a shortage of models beyond the standard adaptation. Three groups of respondents were compared: those who were already a mentor, who would agree to become a mentor, who did not want to become a mentor. The educational and qualification level, research activities, work experience in the specialty, specifics of providing medical care with the account of complexity and responsibility were the comparison criteria. The need to introduce or expand mentoring is recognized by many respondents, and the potential composition of mentors allows us to speak about the prospects for its development.
