Out of the $316.2 billion of private giving in the United States in 2012 (latest year for which real numbers are available), 16% came from foundations. (72% was from individuals). Grants from foundations are a major source of funds that support impact-making organizations in the United States. These numbers are according to a report, “Key Facts on U.S. Foundations,” released by the Foundation Center in New York City.
If a proposal is well-written, most of the mechanics in managing a grant consist of doing what you said you’d do in the proposal. These tend to be fairly obvious: Perform the activities proposed. Collect data as promised in your evaluation plan. Provide mandatory reports on time. Notify the funding office of any significant changes from the proposed plan. Meet any additional requirements mandated by the funding agency.
