This case study highlights a typical example of the kind of gap that exists between centralized planning and implementation. Despite the existence of fairly sophisticated central planning machinery in Ireland and an active desire for reform on the part of the government (with an explicit policy on school location, buildings, curriculum, etc.), the school networks in the County still remain largely outdated and ill-adapted to modern circumstances. This situation results in costly under utilization of resources, a lack of equality of educational opportunity and supply, and inadequate pedagogical provision. The County is highlighted geographically and placed comparatively in the Irish context under the headings of demography, economic and social background, and educational system. Profiles of the school networks are given, and an analysis and a diagnosis are made of the first and second levels respectively. Internal comparative analysis by catchment area is made separately for the two levels under enrollment, transport, teaching staff, curriculum, physical facilities, costs, and financing. Prognoses and proposals for future school networks are made, and an enrollment forecast to 1976 is made against a background of the economic and social development perspective and the demographic trends for the County. The methodology, parameters, and principles of school mapping are presented. (Photographs may reproduce poorly.) (Author/MLF)
