This study aims to determine the influence of visionary leadership, organizational culture, and work motivation on teacher performance, both partially and simultaneously. This research employs a quantitative ex-post facto approach with a causal correlational design. The sampling technique uses cluster sampling, resulting in the selection of three public junior high schools in Cisauk District with a total of 107 teachers. The pilot test aims to determine validity using the Pearson product-moment correlation and the reliability of the instrument. Data collection was conducted through a survey using questionnaires. The data analysis technique uses multiple linear regression analysis, which was preceded by prerequisite tests. The results show that partially, visionary leadership has a significant effect on teacher performance (t-value = 11.110 > t-table = 1.983, Sig. 0.000 < 0.05), organizational culture has a significant effect on teacher performance (t-value = 6.629 > t-table = 1.983, Sig. 0.000 < 0.05), and work motivation has a significant effect on teacher performance (t-value = 9.730 > t-table = 1.983, Sig. 0.000 < 0.05). Simultaneously, visionary leadership, organizational culture, and work motivation significantly influence teacher performance in public junior high schools in Cisauk District, Tangerang Regency (F-value = 222.191 > F-table = 2.696, Sig. 0.000 < 0.05). Therefore, the improvement of teacher performance is not influenced by a single factor alone but is jointly affected by visionary school leadership, a conducive organizational culture, and high teacher work motivation.]]>
