This study proposes a mathematical model for evaluating school performance using Data Envelopment Analysis (DEA), a non-parametric method for assessing the relative efficiency of decision-making units (DMUs). The model addresses key challenges in educational efficiency measurement, such as multi-input/multi-output structures, heterogeneity in school resources, and the need for benchmarking. using DEA as one of operational research techniques, the framework enables policymakers to identify inefficiencies, allocate resources optimally, and develop targeted improvement strategies. The paper discusses theoretical foundations, model specifications, and potential applications in educational management, emphasizing its adaptability to diverse school contexts. Findings aim to contribute to evidence-based policy-making in education systems.
