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. Keywords: advocacy, community health workers, policy, professional development, workforce develop.
