Continuous training of newly graduated nurses (NGNs) depends on several factors related to the characteristics of skills to be developed, the target population, and the organizational context. Few studies describe both how nurses develop their skills and how institutions promote this development. This article aims to (1) describe the behaviors that NGNs use to develop their reasoning skills and leadership and (2) document the organizational elements that facilitate this development. Method. Individual interviews were conducted with nurses (n=34) using a grid of semistructured interviews and two group interviews were conducted with nurses (n=7) and managers (n=19) in two teaching hospitals in eastern Canada. The results show that nurses develop mainly by reflecting on their professional practice in their workplace. However, the lack of time for reflection in the workspace is a considerable obstacle, while managerial leadership is an important asset.
