This report discusses the development and characteristics of the Prospective Student Inquiry Data File and Information System, which is used by the California State University at Chico (CSUC) as part of an effort to increase its student applicant population. Following a brief review of organizational background information, the report is divided into five sections which provide: (1) a detailed description of the purpose and function of the School Relations and Outreach Office, one of the university agencies responsible for student recruitment; (2) information on the Prospective Student Inquiry Data File--function, history, data sources, data entry schedule, specific file record elements, file processing, file output, user population, and output utilization; (3) a discussion of problems caused by the computer-incompatibility on campus that inhibits full use of the Prospective Student Information System; (4) a case study of efforts by the CSUC School of Agriculture and Home Economics to incorporate the Inquiry Data File into a specialized information system that would streamline its recruiting process; and (5) some projections and recommendations regarding the future of the Prospective Student Information System at CSUC. Appendices contain three different prospective student inquiry forms, a sample computer listing of an inquiry report for the School of Agriculture and Home Economics, a flow-chart for the prospective student inquiry response system, and a list of references.
