Demands made on nursing staff are expanding and changing, requiring a broad set of competencies that require evaluation and enhancement in places. This study used the Nurse Competence Scale to measure self-assessed competence among nurses working in three municipal health-care services in Norway. Results indicate that nurses perceive their competence as being satisfactory overall, but there are areas that would benefit from improvement: providing patients' family members with education and guidance, quality assurance, and using research to evaluate and develop services. These competencies could be the focus of departments' future competence plans. The Nurse Competence Scale can be used to assess the impact of training and the efficacy of competence-enhancing actions.
