The purpose of this study is to examine the current literature and have an insight about coaching as a performance improvement tool at school. In today's world, schools have to survive and keep their organizational success in the highest level because of the high expectations from school stakeholders. Taking place in such a fierce competitive environment requires being more effective and efficient. Coaching can be a key to success for schools if it can be implemented in the school as a whole. The previous research findings show that if coaching techniques can be used effectively by the school principal, it becomes an effective motivation resource and performance booster not only for the teachers but also for the other staff and students.
