Most nonprofit leaders understand the importance of building strong organizational capacity, but finding ways to support and strengthen this capacity often poses significant challenges. Nonprofit leaders may hesitate to divert money from direct services when funds are needed to support operations. Some experts in the field also note what they characterize as a "starvation cycle." Funders often are unwilling to provide sufficient funding for overhead costs to support organizational capacity, or they are unaware of the need for this funding due, in part, to grantees underreporting of overhead costs. This strategy brief discusses four approaches that leaders of youth-serving nonprofit organizations can pursue to help support and strengthen their organizational capacity: build accurate overhead rates into contracts and grants, access funding to directly support capacity building, access technical assistance to support or improve organizational capacity, and form partnerships to share administrative services. The brief highlights the experiences of youth-serving nonprofits in using these strategies to build their own organizational capacity. It also identifies some public and private funders' innovative efforts to support capacity building. (Contains 21 footnotes.)
