Leadership Functions in Schools

School principals can perform different leadership functions in their schools. The extent to which they do this and its relationship with their success at their work have been explored herein. A questionnaire was administered to a sample of 430 teachers from 20 schools across all five geographical areas of Tehran. The sampling was done through cluster sampling method. Results show that the principals do not perform all leadership functions and are not successful in doing their job which could be caused by the former.
