This report examines how the curricular offerings of large secondary schools compare with the curricular offerings of small secondary schools. The study is motivated by theories of production which hold that economies are available in large compared to small schools; it is pointed out, however, that larger schools may not take advantage of existing size economies or may take advantage in varied ways. The first section of the paper reviews ways in which the curriculum of a larger secondary school can differ from that of a smaller secondary school and notes reasons for expecting one type of difference rather than another. Topics include analysis of the relationships among educational services, variation in the mix of services, variation in the means employed to provide services, and the cost of services. The second part of the paper presents an empirical assessment of the relationship between scale and the incidence of the various curricular responses. The conclusion discusses policy implications related to the findings of the study which make a convincing case for maintaining secondary enrollment levels at the 400-pupil level. (JHZ)
