The ways in which individual school districts view and staff their business functions vary greatly. This document presents organizational charts and job descriptions of professional positions in the school-business office collected from school districts throughout the United States and Canada. Over 100 job descriptions from 50 school districts are included. The information can help administrators compare their school districts' job qualifications, job responsibilities, reporting hierarchy, and organizational structure with those of other districts. The descriptions are grouped by the following areas of responsibility: chief business administrator; business office; accounting, budgeting, and finance; facilities/buildings and grounds; data processing; food service; maintenance and operations; management-information services; purchasing/warehouse; and transportation.
