The concept of school climate, which means that each school has its own unique atmosphere, is associated with many organizational variables. Organizational citizenship is one of them. Organizational citizenship is formed by the voluntarily positive behaviors of employees in an organization to increase the welfare of the organization. From the teachers' and students' perspective, organizational citizenship is the willingness to take actions to benefit the welfare of the school without any expectation of self-interest. There is a correlation between organizational citizenship behaviors and their attitudes towards school climate. It can be said that a positive school climate increases organizational citizenship behaviors.
