The Resource and Referral Service (RRS), is a central services contractor to the Research and Development Exchange (RDx), which facilitates the flow of outputs from Research and Development (R&D) based organizations, specializing in fast responses to questions from states transmitted by the Regional Exchanges on R&D in education, testing, and evaluation in elementary and secondary education. This paper describes the mission of RRS and the Data Bank which provides information for responses to requests. A discussion of services is also included, followed by issues in the development and use of R&D resources, and the need for evaluation and research in this area. (Author/MBR)
