ABSTRACT The “Cornerstones of Public Health Nursing” describe the values and beliefs that underlie the practice of Public Health Nursing, which is a synthesis of public health and nursing. The impetus for the development of the Cornerstone framework originated from the need to advocate for public health nursing programs, positions, and funding. Grounded in practice, their development engaged stakeholders from the public health nursing community at every phase. The Cornerstone framework has been used over the past decade by educators to teach public health nursing and by administrators in state and local health departments for orientation and continuing education. The Cornerstones have been nationally and internationally disseminated. This paper describes the development and dissemination of the Cornerstones framework by public health nurses in Minnesota and features exemplars from practice.
