In recent years, the role of evaluators in the not-for-profit sector has changed. Increased delivery of social services, government initiatives and associated demands for reporting and accountability have created the need for nonprofits to build internal capacity for program evaluation. As internal evaluators, we are faced with the challenges of external and internal demands for evaluation data and results. Although our experiences are different (one of us the first and only internal evaluator at a small organization, and the other a part of a large evaluation team), we both agree that successful internal evaluation needs to be participatory and requires support from senior management. This roundtable will be an opportunity for internal and external evaluators at all levels, or anyone whose work involves building internal evaluation capacity, to reflect upon their roles, share and discuss challenges associated with supporting not-for-profit work, and brainstorm strategies to build internal evaluation capacity.
