Competency-based continuing education is critical to the professional development of school nurses to ensure the application of timely, age-appropriate clinical knowledge and leadership skills in the school setting. School nurses are responsible for a large number of students with a variety of complex and diverse health care needs. Benner's theory of novice to expert provides a framework for the development of roles and competencies in the practice of school nursing. This manuscript synthesizes research reviewed in 15 articles. Common themes found in the articles include the importance of continuing education and identified barriers to attainment. In response, methods to access continuing education and financial resources are presented. (Contains 2 tables.)
