Description There has been a long-lasting debate between two schools of thought about whether community foundations should be community-focused or donor-focused (Carson, 2003; Gronbjerg, 2004; Hammack, 1989; NCRP, 1994). The former, embodied in the practices of the Cleveland Foundation and many of those established in Midwestern cities, emphasizes community leadership, participation in community collaborative initiatives, and raising unrestricted funds in order to target high priority needs. The latter, embodied in the practices of the New York Community Trust and many of those established in Northeastern cities, focuses on fulfilling the charitable interests of individual donors and on managing donor advised funds. The debate between the above two models poses important challenges on understanding and assessing the performance of community foundations. In line with the community-focused model, the performance of a community foundation may be understood and judged by its effectiveness in terms of raising and directing unrestricted assets in response to the community's common problems. In line with the donor-focused model, however, performance may also be evaluated by its efficiency in acquiring individual donor funds, accumulating financial capital, and facilitating each donor's individual charitable interests. This situation is exacerbated by the lack of consensus by nonprofit scholars and practitioners alike as to how to understand and measure the performance of nonprofit organizations (Forbes, 1998; Herman & Renz, 1999). In light of the call for a broader definition of nonprofit performance that takes into consideration the competing interests of multiple stakeholders or constituencies (Bradshaw, Murray, & Wolpin, 1992; Herman & Renz, 1999; Kaplan, 2001), we propose to understand the performance of community foundations along their dual function as both fundraisers and grantmakers; that is, performance should be indicated not only by organizational effectiveness in acquiring resources and meeting the needs of individual donors, but also by organizational effectiveness in allocating resources and meeting the needs of the community. Such a definition for community foundation performance is consistent with the unique role of community foundations as the bridge between community resources and needs. In fact, it echoes the observation of other scholars that the most successful community foundations incorporate both community-based and donor-based models (Leonard, 1989; cited in Gronbjerg, 2004). Based on the above definition, this paper discusses a national study of community foundations that examines factors associated with their performance. Specifically, the study examines the extent to which community foundations vary in their fiscal performance, grant allocations, and development of unrestricted assets; as well as the environmental (i.e., organizational density, compliance with industry standards), organizational (i.e., age, asset size, revenue, size of service area), and governance (i.e., board performance) factors that lead to such variations. Analysis is conducted on population-level data of 677 community foundations, a national survey of 117 organizations, and subsequent interviews with This study explores the environmental and organizational factors associated with the performance of community foundations. Results of population data analysis revealed that smaller community foundations are more financially efficient and more generous with grant-making. Increased organizational density was positively associated with fiscal efficiency but negatively associated to grant- making generosity. Regional, as opposed to local foundations, were more financially efficient, but local foundations were more generous with grant allocations.
