The present study investigated the relationships between college students' perceptions of instructor credibility (competence, character, and caring) and their perceptions of classroom justice (distributive, procedural, and interactional justice). Results indicate that perceptions of instructor credibility positively predicted perceptions of classroom justice. Specifically, instructor competence predicted interactional justice; instructor caring predicted procedural and interactional justice; and instructor character predicted distributive, procedural, and interactional justice. In short, instructor credibility was most strongly related to interactional (versus distributive and procedural) justice and instructor character (versus competence or caring) was the most consistent predictor of classroom justice.
