According to the findings of research, secondary school teachers reported that the three sub-dimensions regarding diversity management were “medium-level”; the opportunity for teachers to display their knowledge and skills on diversity management was medium-level, diversities were not evaluated at desired level in line with individual/organizational goals and benefits; organizational values and norms regarding diversity management could not be established precisely; diversity was taken into account at medium-level in the administrative actions and practices and as a consequence, a management understanding based on diversity was not presented at desired level and precisely. In their study of administrators and teachers Balyer and Gündüz (2010) found out that they expressed positive opinion, at the “agree” level, for the sub-dimension personal attitude and behaviors but “lower” level with the sub dimensions of organizational value and norms, and managerial practices and policies. They determined that according to the opinions of the teachers, the administrators generally are not at a suffient level to manage the diversity of the employees. Çetin and Bostancı (2011), found that teachers regard the “diversity management” as the least realized by the administrators. In the study of Memduhoglu (2007) on administrators and teachers, it was determined that they had positive opinion for all three dimensions at the “agree” level. The following recommendations are made in accordance with the results of this research: With the aim of providing school administrators with transformational leadership skills, school administrators should adopt transformational leadership understanding which is a participative, democratic and modern leadership style. In schools, an organizational climate approaching diversity with tolerance and allowing employees to protect their ethnical and cultural heritage should be established. School administrators should treat all employees objectively. All the members of the school should implement practices strengthening the interaction among the school stakeholders. This study should be carried out at different educational levels (primary and higher education, etc.) using different methods (qualitative) and different data collection tools (such as observation, meeting and interview, etc.).
