This document summarizes Champlain College's efforts to develop an impact assessment program for its information literacy curriculum. It describes embedding information literacy into a new core curriculum, teaching skills incrementally over four years, and using rubric-based assessments. The authors tracked outcomes in a matrix and used results to inform teaching. They encountered challenges but found success collaborating across departments and emphasizing meaning and usefulness in data presentation. The program emphasizes formative assessment, tolerates uncertainty, and sees assessment as an ongoing, inquiry-based process.
