Within the specific context of Saudi Arabian high schools, I conducted a qualitative study to gain a greater understanding of how decentralization, a significant reform initiative, affected principals and teachers. The study centered around participants' perspectives, challenges, and successes. I actively sought recommendations for improving the decentralization process, focusing mainly on the voices of key stakeholders. The results focused on the voices of these influencers to provide practical guidance for future reforms and improvements in the quality of education for Saudi high schools. In selecting a qualitative study, I employed an interpretive design to explore the experiences and perspectives about decentralization, as perceived by high school principals and teachers in Saudi Arabia. This study was conducted in Jeddah, Saudi Arabia, where decentralization reforms have already been implemented. I looked at recurring themes and patterns that appeared in the participants' narratives because this approach allowed for a greater in-depth examination of their insights and recommendations about the decentralization process. In reviewing the collected interviews, I gained a greater understanding of their experiences and the challenges they faced. The research was specifically designed to capture the nuanced and context-specific aspects of the decentralization implementation within the high school system. High school principals and teachers experienced the impact of the decentralization implementation in a variety of ways, but the main finding revealed that while decentralization was seen as a positive step toward school autonomy, it simultaneously presented challenges related to decision-making, resource allocation, and communications among principals and faculty. The results of the study contributed to a deeper understanding of the process of decentralization in Saudi high schools and provided insights to educational policymakers and practitioners. The research clearly showed that the decentralization of Saudi Arabian high schools is a complex process, encompassing a range of advantages as well as a number of challenges.
