The increasing complexity of vocational education systems necessitates robust administrative frameworks to enhance the effectiveness of Research and Development (R&D) centers. In Thailand, vocational institutions face challenges related to governance, resource allocation, technological integration, and performance evaluation. This study proposes a structural modeling approach to design and validate an administrative framework for vocational education R&D centers using Confirmatory Factor Analysis (CFA). Grounded in organizational theory, management information systems, and evaluation frameworks, the study synthesizes multiple dimensions including leadership behavior, competency development, research management, and institutional policy alignment. A quantitative methodology is employed to validate latent constructs influencing administrative efficiency. Findings reveal that strategic leadership, structured evaluation mechanisms, technological integration, and competency-based management significantly influence the effectiveness of R&D centers. The study contributes a validated model that enhances decision-making, operational efficiency, and research productivity in vocational education systems. The implications extend to policymakers, administrators, and educational planners aiming to optimize institutional performance through data-driven administrative design.
