This assessment examined the presence of anti-citizenship behavior (ACB) in the college classroom by (1) identifying the types of ACB college students use in their classes, (2) identifying the reasons why students use ACB, and (3) exploring the link between ACB and student learning outcomes. The results indicated that (1) participants report four types of ACB (i.e., participatory, technological, physical, and etiquette) used in their classes; (2) participants attribute the use of ACB to either their classmates or their instructors; and (3) perceived classmates' use of ACB is negatively related to student affective learning, perceived cognitive learning, state motivation, and communication satisfaction.
