One form of Regional Educational Agency (REA) is the Educational Cooperative, which was under field development for several years by the Appalachia Educational Laboratory, Inc. (AEL) and the United States Office of Education. The program included an evaluation effort, and the general design, instrumentation, and comprehensive bibliography for that effort are presented herein. The general design is from the perspective of the cooperative, or REA, as organization qua system for problem-solving and decision-making, and some of the ideas may be of use in evaluations of REAs. The instrumentation and bibliography cover areas such as needs assessment, planning, evaluation, and organizational management, and other REAs may find some use for the information on instrumentation and bibliography. A formal statement of the development aspects of the program may be found in the monograph, The Educational Cooperative: A Design for a Regional Educational Agency by Hayes Wilcox, et al. through AEL, Inc.
