The result of the study shows that the role of school administration in diversifying sources of funding for school education is low, and the estimates of the sample of the study about the sources of funding for education in public schools in Sultanate of Oman was (73%) in favor of relying on the funding of the Ministry of Education. The result also shows that there were no statistically significant differences in the responses of the sample members of the study about the role of school administration in diversifying sources of funding for school education as well as the total. The study came out with a number of recommendations such as the need to develop a clear funding strategy by the Ministry of Education, so that schools administrations can diversify their funding sources, and to encourage schools to be productive schools through the establishment of some investment projects of their own. There is also a need to allow the principals of schools to pay governmental fundings as they suit the needs of their schools, to activate the Islamic Waqf (Endowment) in various forms, and to open communication channels with all surrounding public and private institutions of the Omani society.
