<![CDATA[ABSTRACT Improving teacher performance is a crucial factor in achieving sustainable educational quality. However, teacher performance is influenced not only by individual competence but also by organizational factors, including visionary leadership, organizational culture, and interpersonal communication. This study aimed to analyze the effects of visionary leadership, organizational culture, and interpersonal communication on teacher performance, both partially and simultaneously, among teachers at private elementary schools in Serpong District. The study employed a quantitative approach using a survey method involving 125 teachers selected through multistage random sampling from a population of 181 teachers. Data were collected using a five-point Likert-scale questionnaire that met the validity and reliability requirements and were analyzed using descriptive and inferential statistics through multiple linear regression analysis with SPSS. The findings revealed that visionary leadership, organizational culture, and interpersonal communication each had a positive and significant effect on teacher performance. Simultaneously, the three variables also had a significant effect on teacher performance, with a coefficient of determination adjusted (R²) of 0.408, indicating that 40.8% of the variance in teacher performance could be explained by the proposed model. Among the three predictors, organizational culture exerted the strongest influence in the multiple regression model. These findings suggest that improving teacher performance requires strengthening school governance through visionary leadership, a supportive organizational culture, and effective interpersonal communication as an integrated strategy to enhance teacher professionalism and educational quality. ABSTRAK Peningkatan kinerja guru merupakan faktor penting dalam mewujudkan mutu pendidikan yang berkelanjutan. Namun, kinerja guru tidak hanya dipengaruhi oleh kompetensi individu, melainkan juga oleh faktor organisasi, seperti kepemimpinan visioner, budaya organisasi, dan komunikasi antarpersonal. Penelitian ini bertujuan menganalisis pengaruh kepemimpinan visioner, budaya organisasi, dan komunikasi antarpersonal terhadap kinerja guru, baik secara parsial maupun simultan, pada Sekolah Dasar Swasta di Kecamatan Serpong. Penelitian menggunakan pendekatan kuantitatif dengan metode survei terhadap 125 guru yang dipilih melalui teknik multistage random sampling dari populasi sebanyak 181 guru. Data dikumpulkan menggunakan kuesioner skala Likert yang telah memenuhi kriteria validitas dan reliabilitas, kemudian dianalisis secara deskriptif dan inferensial menggunakan analisis regresi linear berganda dengan bantuan SPSS. Hasil penelitian menunjukkan bahwa kepemimpinan visioner, budaya organisasi, dan komunikasi antarpersonal masing-masing berpengaruh positif dan signifikan terhadap kinerja guru. Secara simultan, ketiga variabel juga berpengaruh signifikan terhadap kinerja guru dengan nilai koefisien determinasi adjusted (R²) sebesar 0,408, yang menunjukkan bahwa 40,8% variasi kinerja guru dapat dijelaskan oleh model penelitian. Di antara ketiga variabel, budaya organisasi memberikan pengaruh paling dominan dalam model regresi berganda. Temuan ini menunjukkan bahwa peningkatan kinerja guru memerlukan penguatan tata kelola sekolah melalui kepemimpinan yang visioner, budaya organisasi yang kondusif, dan komunikasi antarpersonal yang efektif sebagai satu kesatuan strategi dalam mendukung profesionalisme guru dan peningkatan mutu pendidikan.]]>
