This paper examines the administrative uses of the microcomputer, stating that high performance educational managers are likely to have microcomputers in their organizations. Four situations that would justify the use of a computer are: (1) when massive amounts of data are processed through well-defined operations; (2) when data processing is highly repetitive; (3) when processing speed is important; and (4) when the task can be performed by a computer, and manual performance is not practical. Tasks that can be automated by microcomputers are discussed for 16 administrative functions. Descriptions of the tasks are based on the capabilities of software recommended by at least two principals in two National Association of Secondary School Principals (NASSP) surveys and two surveys of Florida principals. Four functions--student records, scheduling, attendance accounting, and grade analysis and reporting--are identified as constituting over 50 percent of the NASSP survey recommendations. The remaining functions are listed as athletics, budgeting, financial accounting, food service, guidance, information from data banks, instructional management, inventory and property records, media center, planning, staff/personnel records, and student transportation. Each function is examined in depth and capabilities of the software for each function are highlighted. (WTH)
