Colleges and universities in the United States are being challenged to assess student outcomes and the quality of programs and services. One of the more widely used sources of evidence is student engagement as measured by a cluster of student engagement surveys administered by the Center for Postsecondary Research at Indiana University. They include the National Survey of Student Engagement (NSSE) and its companion projects: (1) Beginning College Survey of Student Engagement; (2) Faculty Survey of Student Engagement; and (3) Law School Survey of Student Engagement. The University of Texas-Austin hosts the two-year variation of the NSSE, the Community College Survey of Student Engagement. With more than thirteen hundred colleges and universities using NSSE, many institutional researchers may benefit from guidance about how to understand and use these data. Drawing on their experience, the authors offer helpful tips and recommendations for institutional researchers on how to analyze student engagement data, including ways to work with multiple years of results and interpret effect sizes.
