The Regional Resource Center (RRC) program mission is to strengthen the capacity of state systems of education and early intervention to improve results for infants, toddlers, children and youth with disabilities and their families. It is one of the longest and most successful technical assistance projects of the Office of Special Education Programs, US Department of Education. The full program currently includes six individual Regional Resource Centers, (RRCs) and one Federal Resource Center, but the focus of this effort is on RRC performance. Network, as used in this report, refers to the six RRCs. Despite continuous evaluation of efforts with clients and in regions, connecting client effects to improved child/student results has challenged the RRCs for years. Their 2002 introduction to the Results Accountability framework (M. Friedman, Fiscal Policy Studies Institute) provided the most systematic approach to date to attempt tracking and connecting changes in student results to changes in the educational infrastructure attributable to RRC technical assistance. RRC Director approval of the RRFC Reporting, Evaluation and Documentation (RED) Workgroup proposal launched the first program-wide effort to aggregate activities and effects of RRC technical assistance.
