<p>As global education evolves, the need for cultural competence training for English language instructors has become increasingly critical, especially in higher education institutions with diverse student populations. This study examines how cultural competence training impacts teaching methodologies, intercultural communication, and the creation of inclusive learning environments. A quantitative research approach was employed, gathering data from 450 participants using structured questionnaires, with 385 valid responses analyzed using SPSS. Advanced statistical techniques, such as Exploratory Factor Analysis (EFA) and Multivariate Analysis of Variance (MANOVA), were utilized to examine the connections between training and its outcomes. The findings reveal that cultural competence training significantly enhances teacher awareness of diverse student backgrounds, their ability to integrate cultural content into curricula, and their sensitivity to cross-cultural communication challenges. Additionally, teachers demonstrated improved adaptability and communication strategies when engaging with international students. By addressing gaps in prior research and offering actionable insights, this study highlights the importance of integrating cultural competence training into professional development programs to foster inclusive and equitable education in globalized academic settings. The findings offer concrete implications for higher education institutions, including refining teacher training curricula, enhancing cross-cultural engagement strategies, and promoting inclusive policies to support diverse student populations.</p>
