This paper examines the historical supply and demand trends of secondary public school administrators serving students in urban, rural, and mixed school attendance areas in South Carolina from 1978 to 1987. This report projects supply and demand trends for secondary school administrators for the next 15 years from 1988 to 2002. The study is divided into three phases. Phase I findings describe supply and demand findings for administrators, principals, and assistant principals in South Carolina from 1978 to 1987. Phase II findings pertain to the years 1988 to 2002. Phase III findings summarize the qualitative data of secondary principals, secondary assistant principals, and secondary teachers in 1987-88, as well as a summary of projected supply and demand for secondary principals and assistant principals as derived from a questionnaire. Overall findings indicate that the supply population of educators certified as public secondary school principals is projected to decline. The supply population will continue to be large enough to fill available demands. Recommendations are provided. (SI)
