The use of rigorous assessment in an Information Literacy program can be used to persuade reluctant faculty and administrators to buy into a program. A "culture of assessment" also assures quality control for internal and external audiences. Information Literacy at Wartburg College is unique in that it is a required component of five core courses in the general education program. This article describes Information Literacy Across the Curriculum (ILAC) at the Vogel Library and how the program has created a culture of assessment at the library and college. The article also discusses how the program is assessed at multiple times and in multiple ways through the use of direct and indirect assessment. This "culture of assessment" has been instrumental in Wartburg's acceptance of ILAC while assuring that the program thrives. (Contains 3 figures.)
