Higher education is seeing renewed calls for strengthening ethics education, yet there remains a dearth of research on the state of ethics education across undergraduate curricula. Research about ethics in higher education tends to be localized and often isolated to fields of graduate study. In contribution to a contemporary, landscape understanding of ethics education, we collected data on the placement and prevalence of ethics instruction within the general education curricula at 507 major U.S. colleges and universities. Our findings suggest that 1) most schools in our study's population do not explicitly require ethics as a part of their general education curricula; and 2) a school's religiosity and research status are positively associated with explicitly requiring ethics instruction for its undergraduate student body.
