<![CDATA[This study aims to analyze the influence of school principals’ managerial competence and work motivation on teacher performance at SMKS Nurul Amaliyah Tanjung Morawa, both partially and simultaneously. The research employs a quantitative approach with a survey method. The population consists of all 40 teachers at SMKS Nurul Amaliyah Tanjung Morawa, and the sampling technique used is census sampling, meaning the entire population was included as respondents. Data were collected through questionnaires, observations, and documentation. The analysis involved validity testing, reliability testing, normality testing, t-test, F-test, and the coefficient of determination (R²). The results show that the principal’s managerial competence has a positive and significant effect on teacher performance, with a t-value of 5.205 greater than the t-table value of 2.026 and a significance level of 0.000 0.05. Work motivation also has a positive and significant effect on teacher performance, with a t-value of 4.205 greater than the t-table value of 2.026 and a significance level of 0.000 0.05. Simultaneously, managerial competence and work motivation have a positive and significant effect on teacher performance, with an F-value of 52.863 greater than the F-table value of 3.25 and a significance level of 0.000 0.05. The coefficient of determination (R²) of 0.668 indicates that 66.8% of the variation in teacher performance can be explained by managerial competence and work motivation, while the remaining 33.2% is influenced by other factors outside this study. Thus, improving teacher performance requires effective school principal managerial competence and high teacher work motivation.]]>
