A logic model is a communications tool that graphically represents a program's resources, activities, priority target audiences for change, and the anticipated outcomes. This article describes the logic model development process undertaken by the California Geriatric Education Center in spring 2008. The CGEC is one of 48 Geriatric Education Centers across the nation, funded by the U.S. Health Resources Services Administration, Bureau of Health Professions. Engaging this diverse group of stakeholders to develop a logic model has added substantial value to program planning, implementation, and evaluation of key performance outcomes.
