In spring 1985, the Office of Student Outreach at William Rainey Harper College (WRHC) in Illinois initiated a study to determine the effectiveness of their responses to telephone and mail inquiries for information about the college. A survey was mailed to a sample of 420 inquirers, asking about their information needs, their evaluation and use of the materials they received, their unmet information needs, their preferred types of information sources, and their age and enrollment status. Study findings, based on a 70% response rate, included the following: (1) over 90% of the inquirers received information from WRHC within 2 weeks of their request; (2) 62% wanted information about a specific academic course or program; (3) 98.7% received some sort of material from the college, with 83% getting a catalog and 50% an application form; (4) 96% described the material they received as helpful and informative; (5) 34% had been prompted to contact WRHC by a friend or relative; (6) when asked what needed information had not been supplied, 21% mentioned the schedule of classes and 16% the names of contact persons; (7) as a result of receiving the literature, 26.6% said they decided to enroll at WRHC; (8) 83% preferred to learn about WRHC through mail to their homes; and (9) about 23% of the inquirers had not discussed the material they received with anyone, but of those who did, 90% discussed it with friends or relatives as opposed to professional contacts. The survey instrument is appended. (LAL)
