The combination of the costs of providing services in sparsely populated areas and the equal opportunity benefits of comprehensive schools generates problems in terms of school district organization. The research reported here examines the relationship between increasing school district enrollment and increasing the distance children have to travel to school. Using a location-allocation methodology, the researchers examined four enrollment levels to find out how much distance would have to increase if reorganization were to occur at any of the target figures (namely, 1,000, 750, 600, and 400 pupils per school district). The results of the study showed that the average distance increase for children would be minimal, simply because most children would not be affected. However, among reassigned children the impact would be significant, averaging more than 10 miles for most alternatives. If reorganization were to occur, the study recommends, small marginal increases in distance would result from setting enrollment minima at 1,000 or 750 pupils rather than 600 or 400. More attractive than a single enrollment standard, however, would be a combination of enrollment and distance standards. (Author/LD)
