Background/purpose. This study aims to evaluate the performance of State Vocational High Schools (SMK) with the status of Regional Public Service Agency at the provincial level. This assessment is conducted out to determine how efficiently schools employ their resources and generate the best performance possible. It is expected that the findings of this study would help authorities enhance management at schools, increase partnerships with the industry, and make students more competitive in the job market. Method/ Material. The approach used in this study is Data Envelopment Analysis (DEA) to measure the relative efficiency of 30 schools. Three input factors and four output variables--obtained through school surveys and interviews--were employed in this research. Result. The study revealed that 11 of the 30 SMKs analyzed achieved the highest efficiency level (score 1). These schools displayed the most efficient use of resources in producing output. Three of the eleven schools were chosen as the primary models to serve as pilot projects in an effort to improve management efficiency in other SMKs. Conclusion. Policymakers can improve the efficiency of school management by adopting the study's conclusions. Schools may raise the competitiveness of graduates by making the most use of their resources, fostering stronger relationships with industry, and making the curriculum more relevant to the workplace. At the provincial and national levels, efficient school models may function as a model for creating vocational education policies.
