Consistent with the commitment of OSEP to a focus on Implementation Science in the process of the State Systemic Improvement Plan, the National Center for Systemic Improvement (NCSI; at WestEd) and the State Implementation and Scaling-up of Evidence-based Practices Center (SISEP; at the UNC Frank Porter Graham Child Development Institute) will collaborate to build the Implementation Science fluency of an internal NCSI Implementation Team for use in support of SEA Implementation Teams, and to track and evaluate SEA implementation capacity through the use of the State Capacity Assessment.
