The study aimed at identifying the role of 'TAMAM' project in the administrative empowerment of schools in the Sultanate of Oman from the point of view of school administrations and their teachers. To achieve the objectives of the study, the researcher used a mixed method, which is based on the integration of quantitative and qualitative research using two tools: a questionnaire and interviews. The study population and its sample consisted of all school principals and their assistants, and members of the school teams from schools implementing the TAMAM project in the academic year 2019/2020. A total number of (62) individuals participated during data collection. The study concluded that participants perceived the pillars of the TAMAM project to have had significant impact on administrative empowerment. The results revealed a lack of stable financial support for the project, shortage of time, a lot of burdens and daily tasks, lack of interest, and lack of follow-up on and encouragement for implementing schools. Add to that, the lack of administrative and technical staff is among the most significant obstacles facing the school, limiting and restricting the roles of school administrations in relation to the TAMAM project.
