Increasingly, staff members in community and public health programs and projects are required to undertake evaluation activities. There is, however, limited capacity for, and understanding of, evaluation within this workforce. Building the capability of individual workers and thereby contributing to the overall capacity among the community and public health workforce has been advocated as one solution. In this article, the "Easy Evaluation" initiative, which seeks to increase the evaluation capability of individual workers and the capacity of the community and public health workforce in New Zealand, is discussed. The theoretical foundations of the evaluation approach (theory-driven evaluation) taught and of the teaching philosophy (adult learning and experiential learning) used are described, along with course content, teaching activities, and participant activities. Although our observations and experiences are that the workshop model is successful in increasing knowledge and skills of participants (building capability), additional support is required for organizations to build evaluation capacity.
