ABSTRACT Objectives: To analyze the motivation of neonatal intensive care nurses and the meanings attributed to the continuity of professional training. Methods: qualitative study, developed between August and December 2018, based on interviews with 16 nurses working in Neonatal Intensive Care in cities in seven Health Regions in the State of São Paulo. The theory of self-determination and narrative analysis supported this study. Results: the search for specialization and qualification of care is the plot, with the motivation for training initially based on the specialization and qualification of care. Over time, they revisit understandings carried out about care, making considerations about training, factors that influence motivation. Final Considerations: the motivation expressed by the nurse in the search for training is shown through movements marked by the limitations apprehended in practice on the care of the risk neonate and the acquisition of knowledge to act with quality in this specific health scenario.
