To organize and coordinate the efforts of many volunteers, a framework for volunteer engagement is needed. The "GEMS" Model of volunteer administration was developed to assist Extension professionals and volunteer coordinators to effectively administer volunteer programs without delivering the program themselves. The GEMS Model is illustrated in a spiral, depicting the continuous process of involving volunteers in community programs and organizations. GEMS consists of 18 steps, which exist in four distinct categories, including: Generate, Educate, Mobilize, and Sustain. The GEMS Model is a tool that will help volunteer administrators and leaders achieve the goals of the organization and its clientele.
