An assessment was conducted to update a tool kit published by the American Association of Occupational Health Nurses (AAOHN) in 1998. The original document, Success Tool for Measuring and Articulating Value, had been a respected resource. Although the AAOHN guide, Demonstrating Value, is a tool with steps and examples for demonstrating value, the intention of this article is to explore the rich data collected during the assessment process, which included interviews with occupational health nurse leaders and an AAOHN member survey. Findings were summarized including data responses compared with occupational health nurses’ tenure in the profession, size of company, job title, and clinic setting (i.e., single- vs. multi-nurse or corporate clinic). In addition, key advice from occupational health nurse leaders was summarized. Justifying services and demonstrating value were viewed by all respondents as essential to the profession as well as for ensuring the quality of occupational health nursing services. A gap was identified between more experienced occupational health nurses and those new to the field, as well as between occupational health nursing settings related to the importance of, and involvement in, demonstrating value.
