The Role of Professional Competence in Mediating the Influence of Teacher Performance Assessment on the Managerial Capacity of School Principals At SMAN 1 Syiah Utama, Bener Meriah Regency

Abstract

The quality of education is greatly influenced by the managerial capacity of the principal, which is determined by the ability to direct, manage, and evaluate all school activities effectively. This study aims to analyze the influence of Teacher Performance Assessment on the Managerial Capacity of School Principals, with Teacher Professional Competence as an intervening variable. The research was conducted at SMAN 1 Syiah Utama, Bener Meriah Regency, using a quantitative approach with a saturated sample of 63 teachers. Data analysis was carried out using Structural Equation Modeling (SEM) based on Partial Least Squares (PLS). The results of the study showed that PKG had a positive but not significant effect on the managerial capacity of school principals, but had a positive and significant effect on teachers' professional competence. Teacher performance assessments have been proven to have a positive and significant effect on both professional competence and managerial capacity of school principals. In addition, teachers' professional competence also has a significant effect on managerial capacity, as well as mediating the relationship between PKG and teacher performance assessment on the principal's managerial capacity. These findings confirm the importance of strengthening teachers' professional competencies through systematic performance coaching and evaluation programs in supporting effective managerial leadership.
