This qualitative study includes focus group research involving 99 experienced community partners across eight California communities using community-based research techniques to capture community voices about their service-learning partnerships with different colleges and universities. Partners commented on their perspectives regarding motivations, benefits to the academic institution and to their own organization, impacts on student learning, and areas for improving partnerships. The analysis affirms the characteristics of effective partnerships of multiple well-established models of effective partnerships developed by higher education, but reveal that community partners have a specific sense of prioritization among partnership factors. In addition, partners revealed a surprising depth of understanding and commitment to student learning, the "common ground" of the service-learning experience. Community partners also voiced challenges and recommendations for their higher education partners to transform service-learning partnership relationships to bridge their "different worlds," and enhance learning, reciprocity, and sustainability.
