The Center for Effective Philanthropy (CEP) is a nonprofit organization focused on the development of comparative data to enable higher-performing funders. CEP’s mission is to provide data and create insight so philanthropic funders can better define, assess, and improve their effectiveness – and, as a result, their intended impact. This mission is based on a vision of a world in which pressing social needs are more effectively addressed. It stems from a belief that improved effectiveness of philanthropic funders can have a profoundly positive impact on nonprofit organizations and the people and communities they serve.
