An evaluation tool, the Evaluation Center Cube (ECC), is presented as a vehicle for establishing an analytic framework and uniting evaluation strategies. The ECC was developed in response to the Kellogg Foundation's need to categorize community-initiated funding proposals. As a classification tool, it facilitates proposal analysis and is comprehensive in encompassing the array of what normally would be windows of opportunity for interventions to benefit youth. The three-dimensional logical structure considers projects by: (1) age; (2) developmental area; and (3) community system providing the service. There are nine age categories and seven developmental domains. The community systems dimension contains eight sub-dimensions: (1) religious; (2) education; (3) justice; (4) public works; (5) economic development; (6) health services; (7) social services; and (8) housing. The ECC represents the first step in needs assessment, information dissemination regarding existing community based programs, and analysis of newspaper coverage of youth programs. It provides an easily understood graphic depiction of beneficiaries of foundation funding, and it may provide a model for other organizations evaluating programs. The ECC is illustrated in figure 1.
