Guidelines for using questionnaires/findings provided through the Student-Outcomes Information Service (SOIS) are presented. SOIS provides institutional decision-makers with information on student characteristics, backgrounds, attitudes, reasons for making various educational choices, activities, educational plans, occupational choices, and subsequent achievements. The six instruments of the SOIS questionnaire series are administered to student populations at different points in their college careers. The guidelines cover: administering the SOIS instruments, including the design of local questionnaire items; procedures and costs associated with different methods of administering the questionnaires; use of the SOIS Questionnaire-Analysis Service, with explanations of the computer-generated reports provided by the service; issues involved in interpreting questionnaire results and integrating SOIS results with other institutional data; and ways in which SOIS results can help in institutional evaluation, review, and decision making processes. Appendices include: the two- and four-year college questionnaires, samples of local questionnaire items, output documentation of the SOIS Questionnaire-Analysis Service, and sample reports from Student-Outcomes Assessment Surveys.
