When the literature is examined, in some studies where the school administrator is considered a variable, only the school principal is considered the school administrator. In some studies, the views of the manager and assistant managers are evaluated together under the manager variable. This study aimed to reveal the metaphorical perceptions of teachers towards the principal and deputy principal to determine whether there is a difference between them and shed light on the scientific studies to be conducted. The research is qualitative, designed as a case study. The study group was formed by 289 teachers working in 9 public primary schools, 9 secondary schools and 7 high schools. The data of the study was collected by interview method and analysed by content analysis. According to the research results, there is a high level and significant difference between the concepts of principal and deputy principal according to the teachers' opinions. For this reason, these two concepts should be evaluated as two separate variables in scientific studies where the school administrator is taken as a variable.
