The Frank Porter Graham Child Development Institute (FPG) is partnering with ZERO TO THREE to support the National Center on Early Childhood Development, Teaching, and Learning through four major activities: 1) building implementation science capacity; 2) designing and supporting a performance evaluation; 3) providing cross-sector partnership and leadership with activities conducted by the National Center; and 4) providing content area expertise. Implementation science capacity building will be achieved through the development of a tiered structure for active implementation capacity building. The project involves the development of a performance evaluation design within an implementation science framework that will allow for continuous quality improvement. FPG will play an active role in cross sector leadership and partnership activities of the National Center.
