This paper outlines a model for multigroup evaluation planning in a rural-education setting wherein the commitment to the structure necessary to evaluate a program is needed on the part of a research and development laboratory, the state departments of education, county supervisors, and the rural schools. To bridge the gap between basic research, development, and dissemination and diffusion in such a setting, a continual 4-cycle evaluation process is set forth (such as has been used with the Small Schools Program of the Development Division in the Northwest Regional Educational Laboratory). In addition, to the narrative in the document, Chart I contains the research and development continuum in terms of 9 phases: research, scanning, invention, prototype, adaption, field test, redesign, diffusion, and adoption; Chart II illustrates the 4-cycle assessment procedure; Chart III shows the basic data flow from the field test sites to the development team; and Chart IV gives the time line and responsibilities flow.
