Health service organizations expect Manager Nurses to develop activities that foster the best quality results both in terms of assistance and in terms of management. To do so, managers have to master management skills in order to understand the activity carried out by the Manager Nurses in an archipelago with several islands. This is a descriptive, analytical and exploratory study of quantitative nature. The data collection instrument was an autofill questionnaire, which included a Perception Scale of the Work of the Manager Nurses. The academic qualifications of the nursing managers are as follows: postgraduate studies in specific areas other than management (15,9%); postgraduate studies in the field of management (36,5%) and master’s degree in different areas (17,5%). The results in the field of the skills of management of nursing care may be the ones that require a bigger investment in terms of training. Regarding the skills in the field of political intervention and advice, the results observed were below expectations. The need for specific training in the field of management is obvious; we were able to prove that most of the Manager Nurses do not have specific training in the field of management, which would allow them to perform the management tasks based on solid knowledge, thus improving the quality of their service.
