Counterpart is a leading international development organization that strengthens the capacities of civil society organizations (CSOs) around the world. Organizational capacity building is central to Counterpart’s original mission of investing in and supporting local organizations to create opportunities for self-defined and locally-owned development. An early contributor to USAID’s Capacity Building (1.0 and 2.0) frameworks and tools, Counterpart’s organizational capacity building approach continues to evolve over time while remaining a participatory process in which our partner CSOs prioritize their needs and forms of assistance so that they can best deliver on their mission.
