Problem Statement: In social open systems, there are basically two determinants of organizational behavior: "organizational" and "personal." The former is mostly related to the aim of the organization, the necessities of the work, whereas the latter is concerned with the traits of the employee. Various studies have focused on the traits of the employee along with their different dimensions. One of these is the locus of control, which can be measured and evaluated as a dimension of personal trait. Although there are some studies that were carried out with students, teachers, and principals regarding locus of control, so far no research has been done with educational supervisors who are crucial actors in the current educational process.
