Thirteen years ago, 276 bachelor's-granting colleges and universities inaugurated a new approach to assessing college quality by participating in the first national administration of the National Survey of Student Engagement (NSSE). This report summarizes what was learned over the NSSE's first 13 years, why the survey is being updated, and new insights and diagnostic possibilities represented by these changes. Although NSSE's companion surveys, the Faculty Survey of Student Engagement (FSSE) and the Beginning College Survey of Student Engagement (BCSSE), are incorporating parallel changes, here we focus on the changes to NSSE.
