In this paper concerning the function of regional service centers serving both metropolitan and nonmetropolitan schools, no effort was made to justify service centers, to compare and describe services in the different states, or to review the literature relating to service centers or intermediate units. Instead, this document presents some introspective considerations for regional service centers' identification of ways to become integral, useful partners in the education enterprise. The topic of discussions are (1) rationale for regional center services; (2) regional service center services: general services (planning, awareness, specialized staffing and liaison) and other services (instructional services, instructional support services, and administrative services). The report concludes that, although there is ample evidence that documents the value of regional service agencies to nonmetropolitan schools, particularly the smaller ones, the more troublesome task is to discover and operationalize services which provide additional advantages to larger schools.
