The cost factors involved in the New Designs for the Comprehensive High School project were compared with the traditional operating costs of a comprehensive high school in the United States. The high school cost analysis was based on expenditure profiles developed by the Educational Research Service (ERS). ERS data were manipulated to derive an estimated cost per high school pupil using the 1.30 secondary/elementary ratio. Typical costs were used in the development of four different scenarios that drew from and expanded on New Designs concepts. The first three analyzed the operating cost impact of New Designs schools with an educational technology focus, partnership focus, and relational staffing focus. The fourth scenario analyzed the cost impact of combining these into an integrated focus. Equipment and material costs increased as technology use increased, but partnership and relational staffing arrangements potentially offset a significant portion of these costs. The more students took responsibility for care and cleanliness of their work spaces, the less likely were custodial and maintenance costs to increase significantly. The more the work environment was organized and operated consistent with the adult world of work, the more opportunities were created to share equipment, materials, human resources, and training activities and to contain costs. Creative partnerships involving shared resources resulted in new access opportunities for students without significant new costs. (YLB)
