This research explored the diffusion process of distance education in schools of public health to determine best practices in the planning and implementation of future programs. The researcher traced the diffusion process by utilizing a multiple-case study methodology using a semi-structured interview to collect the perceptions of Distance Learning Coordinators within five schools of public health and a monitor survey of each program's website to corroborate interview data. The research focused on the implementation of programs and explored why schools of public health developed distance education programs; how schools of public health restructured to facilitate development and implementation of distance education programs; and how distance education was refined to meet the needs of the schools of public health.
