To further the National Institute of Education's goal of ensuring a coordinated and nationally linked outreach capability for providing schools with the knowledge and services generated through research and development (R&D), the nation's R&D centers developed an interorganizational and collaborative school improvement program known as the Research and Development Exchange (RDx). Composed of eight regional exchanges (each representing several R&D laboratories and university-based centers), four central services, and a coordinating committee, the RDx has four major goals: to provide information, technical assistance, and training for school improvement programs; to promote the use of R&D outcomes; to promote coordination among dissemination and school improvement programs; and to increase shared understanding and use of information about client needs in order to influence future R&D efforts. In addition to describing the RDx mission and basic structure, this document briefly highlights two areas in which the RDx has achieved significant success: working with state departments of education in the design, development, and implementation of state-wide school improvement programs; and disseminating and promoting the use of R&D outcomes as they support local, state, and regional school improvement initiatives.
