There seems to be a diversity of opinions regarding the construct-relevant definition of impoliteness. Currently, it has been defined with reference to its occurrence in specific contexts. Universities are among those places where incivility is growing rapidly. Both students' and instructors' impolite behavior have been seen as a serious problem that highly interferes with the goals of education. Hence, the current study attempts to examine Iranian university students' perception of instructors' and students' uncivil behavior. The results indicated that academic incivility can be recognized a verbal, non-verbal, and/or as a combination of both. This study creates awareness about academic impoliteness especially in Iranian contexts and it might be a step towards tackling it.
