Choosing a medical profession and occupation, such as a midwife or a medical technician / nurse, gives us the assumption that individuals who have chosen this occupation are more empathetic and more inclined to help others in difficult life situations. If we take this assumption as correct, we can guess that an educational institution, such as a school / college, will teach and help to acquire the attitudes, knowledge and skills of individuals who have decided to become nurses / technicians much easier. Nursing students with volunteering are united by selflessness, tradition, positive attitude and humanity. This paper deals with the topic of student volunteering, more precisely with the volunteering of undergraduate nursing students in the Republic of Croatia, the Republic of Slovenia and the Republic of Poland. The main purpose of the research was to examine the opinion of nursing students about volunteering and to investigate their involvement in student activities. The survey was conducted from February to May 2021 using a survey questionnaire on Google docs. internet platform. The sample consisted of persons from the undergraduate study of nursing who are exclusively older than 18 years. The aim was to find out the frequency of student volunteering in all three academic years, how they received information about volunteering and whether gender has an impact on volunteering, and to examine their opinion on the organization and promotion of volunteering in public. The obtained results indicate that undergraduate nursing students are engaged in volunteering, but this number could be increased through better education and the introduction of volunteering as a compulsory subject in the curriculum of education of nurses / technicians.
