This publication is the final report of the Illinois Business Management Task Force, which conducted an intensive study of the business and management functions of Illinois' public elementary and secondary schools in 1972. Data for the study were gathered through a survey of a stratified sample of 137 local school districts. The report is organized in five major sections that describe findings of the statewide survey, present a digest of statewide recommendations, describe findings of a survey of the Chicago School System, present a digest of Chicago recommendations, and briefly discuss strategies for implementation of the task force's recommendations. The 21 subsections comprising the statewide report examine in turn various functions of Illinois' elementary and secondary school; the 20 similar subsections on the Chicago School System cover essentially the same functions.
