" Grants are a form of federal assistance consisting of payments in cash or in kind for a specified purpose and they represent an important tool for achieving national objectives. They vary greatly, including in the types of programs they fund, the methods they use to allocate funds to recipients, and the amount of discretion they give to the grant recipient on how the funds are spent. The Office of Management and Budget (OMB) has previously estimated that grants to state and local governments represent roughly 80 percent of all federal grant funding, with the balance going to recipients such as nonprofit organizations, research institutions, or individuals. In a time of fiscal constraint, continuing to support the current scope and breadth of federal grants to state and local governments will be a challenge. In response to a request, this report (1) provides information regarding the amount of grant funding to state and local governments for fiscal year 2011, how such funding has changed over the last three decades, and difficulties related to identifying the exact number of such grant programs; and (2) identifies selected grants management challenges that have been identified in previous work by GAO and federal IGs over the last several years. Towards this end, GAO analyzed data from OMB and the Catalog of Federal Domestic Assistance and conducted a review of previous reports from GAO and federal IGs. "
