The study aimed to identify the level of strategic planning skills among managers of primary education schools and its relationship to the development of academic performance in the Sultanate of Oman. The researcher used a descriptive correlational method to achieve the study's objectives. A questionnaire was used to collect data and information, ensuring its validity and reliability. The questionnaire was administered to a sample of 736 male and female teachers in primary education schools in the North Al Batinah and South Al Batinah governorates in Oman. The study's most important results were as follows: The level of strategic planning skills among managers of primary education schools in the North Al Batinah and South Al Batinah governorates was found to be moderate. The results also revealed no statistically significant differences in the study sample's estimates of the level of strategic planning skills among managers of primary education schools in the two governorates based on study variables such as gender, educational qualification, and experience. Furthermore, the study found that the level of academic performance in the North Al Batinah and South Al Batinah governorates was moderate. There were no statistically significant differences in the study sample's estimates of academic performance in the two governorates based on study variables such as Gender, Academic qualification, Experience, Enrollment in the specialized institute and School District. The study also revealed a positive and statistically significant correlation between the level of strategic planning skills among managers of primary education schools and the development of academic performance in the North Al Batinah and South Al Batinah governorates in Oman. Based on the study's results, several recommendations were made, including providing all necessary resources, financial and human, to implement strategic plans for the development of academic performance. It is also necessary to increase the delegation of authority to school principals to enable them to effectively implement strategic planning processes, thereby contributing to the development and improvement of their schools. Additionally, enhancing communication programs between schools and the community is important, as it enables schools to analyze the external environment, understand its needs and requirements, and contribute to developing positive attitudes and desires towards improving school performance. The study also emphasizes the need for the specialized vocational training institute to provide training programs that contribute to the development of future foresight skills, event prediction, and improvement of the education system in Oman. Furthermore, there should be a focus on follow-up and supervision of school principals in implementing school plans, with feedback provided by the educational administration supervisor.
