Partnership has emerged as an increasingly popular approach to privatization and government-nonprofit relations generally. While in principle it offers many advantages, there is no consensus on what it means and its practice varies. Following a review of partnership literature, the article refines the partnership concept, developing two definitional dimensions: mutuality and organization identity. Based on these dimensions, partnership is defined on a relative scale and is distinguished from other relationship types: contracting, extension, and co-optation or gradual absorption. Examples of each are provided. The model enables actors to assess their relative tolerance for partnership approaches, and provides a common language among potential partners. Linking its defining dimensions to partnership's value-added assists partners to advocate for partnership approaches from an instrumental as well as normative perspective. The model and inter-organizational relationship matrix can inform continuing theory building and practical experimentation both to refine defining dimensions and indicators of partnership practice, and to enhance responsiveness to partners' expectations of partnership.
