The focus of classroom incivility research thus far has been at the individual discipline and large public or specialty institution level, which limits the generalizability of findings. Surveying undergraduates (N = 150) at different types of schools (2-year public, 4-year public and 4-year private) and majors on their perceptions of incivility in college classrooms found that older students and students planning on attending graduate school rate uncivil behaviors as more serious, and white students who are not gun owners are more likely to report seeing such behaviors more frequently. Suggestions for future research and novel methods to reduce incivility are discussed.
