The objectives of this study were to identify the student behaviours associated with teacher stress and determine the types of teacher behaviours that may elicit these stressful student behaviours. Student teachers (n = 186) and their supervising teachers (n = 77) completed a stressful student behaviour questionnaire, a teacher behaviour questionnaire, and a teacher stress survey. Results showed that student lack of effort in class was most strongly associated with teacher stress. In addition, teacher behaviours were correlated with students' behaviours of coming to class unprepared. However, few significant correlations were obtained when student behaviour and teacher behaviour data were provided by different sources.
