Determining and discerning expert practice: a review of the literature.

Although the nature and characteristics of expert practice have been described in the literature, the description is incomplete. How expertise is gained is not fully understood, and definitions of expert competencies have yet to be developed. Essential issues for education arise from the demand for knowledge for expert practice. Because expertise is gained in the context of practice, expertise cannot be achieved out of context or taught as an academic exercise. A clear picture of the practice of expert nurses is necessary so that those in the profession can know and articulate expert practice and direct it to the community.
