The extant studies reveal a considerable mismatch between students' and teachers' perceptions of student stress. The present study compared the judgments of teachers-in-training (N = 109) with the responses of first- and sixth-grade children (n = 56 and 93, respectively). The following questions are addressed: (a) Do teachers' judgments of the stressfulness of children's experiences correspond with those of the children themselves? (b) Do teachers' perceptions differ according to general developmental status (first grade level versus sixth grade level)? (c) Does the amount of teaching experience have a significant influence on ratings? Results revealed that teachers' judgments corresponded more closely with the children's ratings at the first grade level than at the sixth grade level. However, teachers' perceptions did differ according to grade level for the majority of life events. Furthermore, there were no significant differences between the ratings of the experienced and inexperienced teachers at either grade level. (Contains 5 tables.)
