Based upon the historical review and case studies reported in the first section, section II develops a rationale for restructuring the county school system or middle echelon unit of school administration in the State of Iowa and for determining the need for a unit of school government operating between local school districts and the State educational agency. Three questionnaires submitted to county school superintendents and consulations with selected educators provided the basic data utilized in the study. Focusing on the practicability of a multicounty service agency program for Iowa, the report is divided into seven chapters: (1) The historical development and current status of the county unit of school administration in Iowa, (2) the major needs of local school districts in the State creating the need for a restructured educational service agency, (3) proposed criteria for the establishment of multicounty regional educational service agencies, (4) the role and function of such agencies, (5) their governance and financing, (6) major benefits to be derived from the establishment of a network of such agencies, and (7) a proposed State legislative action program. Documents EA 001 332 through 001 336 report the findings of a single study funded under Title III of ESEA. (JK)
