An Evaluation Policy helps a funder set high expectations as a learning organization. It clarifies for program officers and the staff that the foundation is interested in understanding what works and in learning from its mistakes. A policy eliminates the constant policy-level debate about what and how a grantee program is to be evaluated and what resources will be devoted to evaluation. It makes accountability part of the corporate culture and imbeds a higher-level of thinking about both grantee and foundation performance.
