At Valparaiso University's main library, the Christopher Center for Library and Information Resources (formerly the Moellering Library), student employees are an integral part of day-to-day operations. Students work at the reference desk and must be able to handle reference questions. Since the fall 2000 semester, the Reference Services Librarian has been creating a training program for the student assistants, consisting of an initial training period and a series of quizzes combined with review sessions. Student assistants are also indispensable in Instruction Services. These students are charged with library web site and instruction materials' updates. Methods, lessons learned throughout the process, and quiz questions are used to illustrate the development of the training program. Student performance evaluations and feedback are positive.
