Introduction: Nursing profession has been present since the beginning of time. Nowadays, nursing is the most numerous and one of the most important professions in healthcare. It is believed that the beginnings of nursing were recorded around the year 300 under the rule of the Roman Empire because already in those years the Roman Empire tried to establish hospitals in every city they had under their rule. Formal nursing/technician education programs have changed throughout history, today they are becoming more comprehensive and scientifically based, and the educational system is being structured in a way to meet the growing demands of health care. Special emphasis is placed on contemporary educational trends, including the integration of technology and a multidisciplinary approach in training nurses for the complex challenges of modern healthcare. Objective: The aim of the diploma thesis is to present the views of nurses and technicians at the Clinical Hospital Center Split about the need for specialist training in nursing. Results: 161 respondents participated in this research. Of the total number of respondents, there were 136 (84.5%) women and 25 (15.5%) men. The largest number of respondents were between the ages of 26 and 35, 35.4% of respondents, and the largest number of respondents were those with completed undergraduate studies, 49.7% of respondents. A total of 63.4% of respondents worked in the COVID center. Statistical analysis showed no statistically significant difference by gender in attitudes towards professional/specialist development (p=0.49), but statistically significant differences were observed in attitudes towards professional/specialist development depending on age (p=0.01). Conclusion: This study showed that middle-aged nurses and technicians (36-45 years) had more positive attitudes towards specialist training, and they also had more positive attitudes towards the improvement of health care. Nurses and technicians with completed graduate studies have more positive attitudes about specialist training, and the most positive attitudes towards specialist training are held by nurses and technicians from the post of OHBP (surgery). Nurses and technicians who worked in the COVID department have the most positive attitudes towards specialist training. Modern nursing faces numerous challenges, one of these challenges in the Republic of Croatia are nursing specializations. The first specialization at the academic level is the specialist training of bachelor's degrees in nursing in the field of emergency medicine, which has been launched and achieved excellent success.
