Instructor credibility, which is defined as "the attitude of a receiver which references the degree to which a source is seen to be believable",[12] consists of three dimensions-, competence, character, and caring.

Instructors who demonstrate competence, character, and/or caring are perceived to engage in a variety of effective instructional communication behaviors such as argumentativeness,[15] verbal and nonverbal immediacy,[16] affinity seeking,[14] and assertiveness and responsiveness.

According to studies, when instructors exemplify the qualities of character (i.e., kind, virtuous, good) and caring (i.e., empathetic, understanding, responsive), students report a greater likelihood of communicating with them.

Instructors who are interested in how students perceive their competence, character, and caring should examine how their in-class communication behaviors contribute to these perceptions.

[43] Jürgen Habermas in his theory of communicative action developed four validity claims (truth, sincerity, appropriateness and understandability) leading to the concept of credibility.
