This study examined the implicit and explicit students’ considerations while rating their teachers’ performance. Its purpose was to reveal that if there are things those students evaluators take into considerations in supplement to the institution made written evaluation criteria. To conduct the survey study, 37 teacher educators and 201 student evaluators of teaching participated in filling the questionnaire. Generally, the survey results indicated that the student evaluators of teachers’ performance take into account the written (explicit) criteria on the one hand and unwritten (implicit) criteria on the other hand during the time of rating their teachers’ performance. The results of student evaluations of teachers’ performance have immense instructional and administrative significances in the Colleges of teachers’ education. However, it has also some negative influences on the instructional processes. Since the student evaluation of teaching is a critical component of the performance appraisal of teacher educators, the Colleges of teachers’ education should give intensive attention to the entire process of student evaluations of teaching.
