This final report of a 5-year dissemination capacity building program traces its development from the conceptual stage through the current stage of institutionalization of dissemination within the state department of education, reviewing major program components as well as the organization and administration of the program. A major aspect addressed is the revitalization and expansion of the linkage concept during the capacity building period. A discussion of this expanded concept highlights the role of state-employed linking agents and of part-time linkers within four "education audiences": school districts, colleges and universities, the state department of education, and education related agencies. The evolution of the statewide coordinated communications network reflects the roles of both official and unofficial linking agents. The conclusion addresses the impact of the program on a broad range of user audiences and on the improvement of educational practice in South Carolina, including results and benefits. Appendices include the organization of the Education Products Center, workshop evaluation checklists, statements of agreement, SHARE collection and distribution guidelines and forms, a guidebook for developing publications and audiovisual materials, user statistics on technical assistance, and resource bulletins. Eight references are cited. (Author/RAA)
