Trust is considered as one of the essential elements at schools. Although it is important, there is relatively little research on trust in educational settings. Research indicate that trust across school affects much of a school's functioning and it is a critical resource as principals embark on improvement plans. In this regard, it is a matter of question whether teachers trust in their principals as school leaders, in their administrative implementations and in their principals' personalities. Therefore, this qualitative study purposed to discover teachers' opinions on their trust in their school principals. Results reveal that teachers of this sample do not trust in their principals in all sub-themes in general. It can be concluded that there is a lack of trust in their principals in all sub-themes among teachers at schools. It is recommended that principals should be chosen and appointed to their posts with a more careful way.
