PASS produces student schedules. This manual offers an operational record of the PASS system, and describes its structure within the total registration process. The primary goals of PASS, a "choice-course" system, are to satisfy student program requirements and equally distribute class load through the master schedule from a total assimilation of inputs. The operational procedures and functional relationships involved in the assimilation of student requests, faculty resources, and space utilization requirements are outlined in detail. The system uses COBOL and the IBM 7090 computer utilizing student requests and the class schedule as the basic sets of input data. Underlying the programming system is a structure of academic concepts and associated goals that form its directional philosophy. Major emphasis is put on the alignment of the class assignment process within the entire operation of the academic term, while providing opportunity for meeting unusual student needs. The key to this network of control is the centralization of master schedule construction in the Office of Schedules and Space. Representative samples of many forms, input documents, reports, and output control information are included in the appendices. (DS)
