While most grantmakers recognize the importance of measuring impact, too many are reluctant to invest in grantee evaluation capacity. As a result, many nonprofits face unfunded mandates to provide data they have neither the time nor resources to collect, an issue brief from Grantmakers for Effective Organizations finds. The brief, How Can We Help Our Grantees Strengthen Their Capacity for Evaluation? (8 pages, PDF), highlights suggestions from foundations that have long supported capacity-building efforts, including assessing a foundation's own capacity for evaluation; encouraging a sense of ownership among grantees around the evaluation process; and combining group-based and one-on-one training. The brief also urges funders to invest in capacity building at the organizational, not just individual, level; to start small and manage expectations; and to fund capacity-building initiatives over time and within the context of a long-term funder-grantee relationship.
