People form organizations by getting together in order to realize the goals that they might not manage to realize alone. Organizations differ from one another by various distinctive characteristics. However, their success is related to the level of goal fulfillment. People working more effectively and efficiently within the organization may create the need to form a new team or group. Forming a new team and sustaining it generally requires a more active and participative approach than the existing approach. If an individual in a team feels happy and successful within the concept of "us" and has a sufficient level of job satisfaction, team work can be considered efficient. Team understanding in schools means that all employees, especially teachers, integrate around common goals and are willing to act with a feeling of "unity" in order to realize those goals. Administrators, teachers and other staff often take responsibility for the parenting of students, and the team spirit at school can be related to the other parts of the society. Particularly, teachers' team understanding is very important in terms of effectiveness of education institutions. The present study has been conducted in order to evaluate teachers' understanding of team work in terms of different variables.
