Ripple Effect Training, a new train-the-trainer program, was implemented by the Oregon State University Master Gardener program in 1999. The goals were to increase veteran volunteer commitment and participation in the Master Gardener training program and to reduce program expenses. During a 2-day workshop, participants received instruction on the training modules and teaching strategies for adult learners. They completed a self-efficacy evaluation after the workshop and again after delivering the training. Evaluation showed they had a high level of confidence prior to delivering the training, and this confidence was elevated after completing the task. Additionally, the new Master Gardener trainees felt the quality of instruction from the Ripple Effect Trainers was similar to that of Extension agents and state specialists.
