This naturalistic study was done to determine whether or not the graduate curriculum was adequately preparing students to function in the advanced nursing role. This article focuses on the advanced nursing practice of four master's-prepared child health nurses. Vignettes of this practice are highlighted and they are assessed using the domains of nursing practice that were described by Benner (1).The entire study, involving 30 master's-prepared nurses, determined that additional attention in the graduate program needs to be placed on the following areas: development of collegial relationships with physicians and other health care providers, development of successful strategies for influencing bureaucracies to respond to patients' and families' needs, articulation and validation of the value of the role of the advanced nurse practitioner, and development of the formal and informal consultation function.
