The aim of the research reported on here was to determine the perceptions of school administrators and teachers working at Anatolian high schools on the characteristics of effective schools. The determined perceptions of teachers and administrators were important for creating more efficient educational domains by sharing leadership among stakeholders in education management. We used the Relational Survey Model to study a group composed of teachers and school administrators working at Anatolian high schools in the Ankara province of Turkey. The sample for this research consisted of 300 teachers selected through proper sampling from within the population. Data obtained from participants using the Effective School Scale were tested by t-test and one-way ANOVA. A significant difference was found between the views of school administrators and teachers regarding the effectiveness of Anatolian high schools in the Ankara province. This study found that the school administrators deemed the Anatolian high schools of Ankara to be a lot more effective than the teachers thought they were. As a conclusion, suggestions for increasing the effectiveness of schools are presented.
