Data from the National Community Health Worker Advocacy Survey (n = 1661) assessed the relationship between CHW professional advocacy and CHW demographics, and work characteristics. Qualitative data articulated the quality of professional advocacy efforts. Approximately, 30% of CHW respondents advocated for professional advancement or collaborated with other CHWs to advance the workforce. Advocacy was more prevalent among CHWs affiliated with a professional network. CHW advocacy targeted recognition of the field, appropriate training and compensation, and sustainable funding. CHW professional advocacy is imperative to advancement of the field.
