Classroom incivility is a major concern in higher education today. Yet little study has been done of student perceptions of behavior in the classroom. Based on a survey of 3,616 students at a Midwestern public university, the present study provides useful information to faculty members and administrators about the behaviors students find most uncivil and how frequently they are experiencing these behaviors. In general, it appears that students are experiencing a fair amount of at least moderately uncivil behavior in their classes. These results have implications for how faculty and administrators develop policies designed to guide students toward appropriate behavior. (Contains 2 tables.)
