This document is a report on the City College of San Francisco Decision Support System (DSS). The DSS is a Web-based information system, designed to provide quick access to college information and services for students, faculty, and staff. It includes data on student demographics, course offerings, productivity of departments, student success rates, course completion percentages, degrees, and certificates. Data can be obtained through the DSS for specific courses and sections as well as for different campuses and the entire community college. Survey results from students, faculty, and staff show that the DSS is viewed as a very useful college service. Other survey findings include: (1) the chair of the Mathematics Department used the system to look for unmet demand among match courses and sections; (2) the English Department was able to reduce the number of students turned away from classes by 400; (3) by looking at individual campuses and student characteristics, administrators were able to plan the most appropriate courses for students attending a specific campus; and (4) the DSS made it easy to answer a benchmarking survey from another college. This report recommends that the college use the DSS to make more informed decisions on programs and services. Appendices provide specific information on the technical processes of the DSS and available databases. (MKF)
