<![CDATA[This study aims to analyze the influence of Professional Competence and Perceived Organizational Support on Teacher Performance through Job Satisfaction as a mediating variable in certified vocational high school teachers in Makassar City. The study used a quantitative approach involving 89 certified teachers as respondents. Data were collected through questionnaires and analyzed using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method. The results showed that Professional Competence had a positive but insignificant effect on Teacher Performance. Perceived Organizational Support also had a positive but insignificant effect on Teacher Performance. Conversely, Job Satisfaction had a positive and significant effect on Teacher Performance. Professional Competence had a positive and significant effect on Job Satisfaction, and Perceived Organizational Support had a positive and significant effect on Job Satisfaction. Furthermore, Job Satisfaction was proven to be able to positively and significantly mediate the influence of Professional Competence on Teacher Performance and the influence of Perceived Organizational Support on Teacher Performance. In both relationships, Job Satisfaction acts as a full mediator because the direct influence of Professional Competence and Perceived Organizational Support on Teacher Performance is insignificant, while the indirect influence through Job Satisfaction is proven to be significant. This finding confirms that Job Satisfaction is an important mechanism linking individual resources and organizational support to improved Teacher Performance.]]>
