This study investigated the influence of strategic planning on school performance and achievement outcomes within the Districts of Jiabong, Motiong, and Wright I and II of the Schools Division of Samar during the School Year 2023-2024 academic year. It addressed the profile of school administrator-respondents, the level of strategic planning implementation, school outcomes, achievements, and their interrelationships. Employing a descriptive-correlational design, the study provided insights into administrator demographics, attitudes toward strategic planning, and the extent of strategic planning implementation. While a high level of implementation was observed in areas like execution, communication, and resource allocation, no direct correlations were found between strategic planning and outcomes like academic achievement or attendance. However, positive associations emerged between communication/engagement and collaborations with external organizations. Administrator characteristics like age, experience, or training had limited influence on planning implementation. Interestingly, a negative correlation existed between administrator attitude and the number of accreditations, suggesting a potential disconnect. The study highlighted the value of strategic planning beyond direct outcomes. Focusing on communication, engagement, and resource management within the planning process might be more crucial in leveraging partnerships and ultimately achieving educational goals.
