CEP's research shows that program officers can be the distinguishing factor between a foundation that makes a difference—and one that simply makes grants. Working Well With Grantees: A Guide for Foundation Program Staff offers program staff critical guidelines for building better relationships with grantees. The findings and suggestions in the guide are based on data from tens of thousands of surveys of nonprofits conducted by CEP during the past decade. The updated, summarized, or expanded findings from six of CEP's publications focus on how foundations and grantees can best work together.  In addition, new data and analysis are included about what foundations might want to consider when declining funding to nonprofits, based on surveys of declined applicants.
