Librarians at a Midwestern, midsized state university studied the application of their flexible programmatic information literacy rubric to one-shot first-year writing library instruction. Ten librarians taught 23 sessions of first-year writing on information access skills and assessed each class using the flexible programmatic information literacy rubric. The results emphasize how a flexible rubric can both assess student learning and provide librarian instructors with autonomy to use methods and lessons that feel authentic to them.
