Meanwhile, the researcher used the comparative method to compare between the ways of selecting qualifying and training headmasters in the Sultanate and in other countries. The researcher checked the reliability of the tool using the Inter- Rater Reliability during the round. That method was used in this study in order to check reliability by measuring the degree of agreement between experts for every section in the instrument. The reliability value indicated (0,80).
