An analysis of survey responses from a sample of registered nurses on competency characteristics for their occupation is presented in this document. (Registered nurse is one of seventeen occupation groups included in this research.) The competencies are reported in five categories: (1) those competencies selected by the respondents from a list of 720 health occupations competencies; (2) the percentage rate which respondents reported practicing the competency item; (3) type of competency (indicated as the performance of a physical skill or action, or an understanding or mental comprehension); (4) use frequency (daily, weekly, monthly); and (5) training needed to achieve proficiency in that competency (formal instruction, demonstration, on-the-job). (The final report of the survey is available as CE 018 899. Survey results for the other occupational groups are also available--CE 018 900-916.) (JH)
