Community-university partnerships for research and action are at the heart of many fields in the social sciences including public health, urban planning, education, and community psychology. These partnerships involve individuals from different backgrounds and disciplines working together to address social issues of importance to the community. This article proposes an interactive and contextual model for developing and sustaining community-university partnerships. The phases in the model include gaining entry into the community, developing and sustaining a mutual collaboration (developing trust and mutual respect, establishing adequate communication, respecting human diversity, establishing a culture of learning, respecting the culture of the setting and the community, and developing an action agenda), and recognizing the benefits and outcomes of partnership work. The model also includes the potential challenges that might threaten the partnership, such as resource inequality and time commitment.
