Diverse guidance exists on how to best design and use a TOC. In this curriculum (Theory of Change: Facilitator’s Guide and all accompanying materials), we present one method that does its best to align to the requirements of creating a development hypothesis for Development Food Security Activities (DFSA) funded by USAID’s Office of Food for Peace (FFP). Previous experience in program and TOC development, participant feedback from six years of TOPS workshops, and input from the FFP Monitoring and Evaluation Team all helped craft this curriculum. We update it each year to align to the most current FFP guidance for DFSA implementers and to share newly discovered training tips.
