The National Survey of Student Engagement (NSSE) and its companion projects serve colleges and universities committed to monitoring and improving the quality of the undergraduate experience. While participating institutions receive detailed customized reports, the "Annual Results" series presents noteworthy aggregate findings from the most recent administration. This report presents selected results from students at 512 U.S. institutions or subsets of that group where supplemental survey items were appended to the survey. It also reports selected results from NSSE's two companion surveys, the Beginning College Survey of Student Engagement (BCSSE) and the Faculty Survey of Student Engagement (FSSE). Colleges and universities increasingly prioritize interventions that promote success for all students. Are these interventions working? Are they reaching the students who need them? What else should colleges and universities be doing to ensure that all students thrive and derive the maximum educational benefit? These important questions motivate this year's report. The report examines NSSE results that bear on support for learners who are challenged by their coursework and how a "growth mindset" corresponds to student engagement. It also presents findings on students' perceptions of safety and belonging at their institution. The BCSSE analysis focuses on dual enrollment--taking college courses while in high school--and how that experience can prepare students for what awaits them in college. The FSSE results were used to investigate variations in selected teaching practices as related to faculty gender and racial/ethnic identity.
