The Diverse Learning Environments (DLE) survey captures students’ perceptions regarding the institutional climate, student learning outcomes (e.g., pluralistic orientation), and campus practices as experienced among faculty, staff, and peers. The Cooperative Institutional Research Program (CIRP) has administered the DLE survey since 2011. This year, 2015, marked the survey’s fifth administration. The survey collected data from 19,580 student respondents attending 26 colleges and universities across the United States. This report discusses students’ experiences with witnessing discrimination on campus, analyze how students contest discrimination, and suggest practices that may lower instances of discrimination on campuses.
