The American Association of Colleges of Nursing's (AACN) Essentials of baccalaureate and master's degree education require teaching population health skills in nursing programs. Clinical site placement for learning population health skills is hoped to be beneficial for both students and the agencies. This article reports on the experience of placing undergraduate and graduate student groups at an agency serving adults and children with intellectual and developmental disabilities (I/DD) as well as many chronic health conditions. Each group of students developed a population health assessment and program plan, with each group building on the efforts of previous groups. The work of multiple student groups has assisted the agency in improving care for their clients, managing health issues associated with aging and chronic health conditions, and making organizational system changes. Lessons can be drawn from these experiences that are of benefit to others developing population health clinical experiences for nursing students.
