摘要：Extension master volunteer programs, such as master naturalist and master gardener, often focus heavily on volunteer education. The model presented here describes the full life cycle of a master volunteer's experience in the program, putting education in the context of other essential program components. By zooming out to a wide-angle view of the master volunteer experience, the model provides guidance for improving the program by highlighting the many points in the cycle at which program managers can support volunteers so that they can be successful and sustain their volunteer service.
