This monograph provides an overview of the history and development of the Southeast Idaho Teacher Center Consortium (SITCC), which is, geographically, the largest rural teacher center in the country, serving 70 public and private school systems in an area of approximately 54,600 square miles. The monograph's first section presents an overview of the SITCC, including information on geography, population, goals, design, liaisons, training, planning councils, community resources, delivery systems, and funding. Other sections are written from several perspectives: those of the policy board, director, field agents, users, consultants, and linking agents. Individuals in each of these roles contributed information on their particular problems, decisions they were called upon to make, and solutions they found to difficulties they encountered. Many of the problems discussed in these sections were pointed out as unique because of the rural nature of the teacher center's setting and because of the distances between the members and SITCC headquarters. An appendix contains a data summary of the services delivered by the SITCC between 1979 and 1981 and includes information on workshops, inservice courses, technical assistance, demonstration lessons, needs assessments, and provision of resources, materials, and information. Other appendices present staff development documents, professional development team training comments, a map of the SITCC service regions, and a map of the SITCC client systems. (JD)
