The California Education Information System (CEIS) was developed to provide integrated information processing for educators at every level of operation. The objectives of CEIS are to make available through a state-wide system for local district use, complete, current and reliable information about education at the local and state level. CEIS provides a flexible and comprehensive means of obtaining better information for the management of educational programs. At the same time, CEIS automates most of the routine information processing. This document presents an overview of the important features of the two new subsystems that constitute CEIS. The business subsystem currently includes five applications: Control, Accounts Payable, Stores Inventory, Personnel/Payroll, and Financial. The pupil subsystem is divided into nine applications: Process Control, Master File Maintenance, Attendance Accounting, Mark Reporting, Test Reporting, California Guidance, Educational Planning, Student Scheduling and Master Schedule Builder.
