INTRODUCTION AND GOALS: Mentoring in nursing is a complex process in the development and professional training of bachelors of nursing. The aim of this paper is to assess the quality of mentoring work in nursing. Research shows that it is necessary to talk about the specifics of mentoring in nursing, and this presentation of results is useful and important for insight into the further development of mentoring in nursing. METHODS: A retrospective research study was conducted to assess the quality of mentoring in nursing in the period from 21.09.2020. until 25.09.2020. Two surveys were conducted to assess the quality of mentoring work. One survey was intended for mentors and their self-assessment of the quality of mentoring work, and the other survey was intended for students who assessed the quality of mentoring work. The research involved 140 mentors and 140 nursing students and bachelors of nursing who voluntarily agreed to fill out a questionnaire on self-assessment/assessment of the quality of mentoring work. RESULTS: Assessments of the quality of mentoring work by nursing students and bachelors of nursing average grade is 3,36. The best rated claims are related to education, sharing knowledge and experience, and getting to know the specifics of the department and the health care of patients that are specific to some departments. The worst rated claims are related to the time spent in practice classes with students. The arithmetic mean of the self-assessment of mentoring work is 4,59. The best rated claims in the self-assessment of mentoring work are related as in the assessment of students for education, knowledge sharing and familiarization with the specifics of the department and patient care that are specific to some departments. The claim that students are not released earlier from practice classes was rated the worst. In the self-assessment of mentoring work, only one statement: "I do not let students out earlier from practice classes" was rated with a score of 1 by 3 surveyed mentors. The self-assessment of the quality of mentoring work by mentors is significantly higher compared to the assessment of the quality of nursing students and bachelors of nursing. There is no significant difference in the quality of mentoring work between masters of nursing / graduate nurses and bachelors of nursing. There is also no significant difference in the quality of mentoring work with regard to years of work experience. CONCLUSION: Mentoring in nursing is a complex process in the development and professional training of bachelors of nursing. In nursing, theoretical and practical knowledge complement each other, so a very important role in education is played by the mentor himself, ie the quality of his knowledge, knowledge transfer and mentoring skills.
