This study aimed to assess the productivity of higher education faculty by developing a structural model incorporating predetermined factors such as transformational leadership exhibited by academic heads, the faculty's cultural intelligence, and self-efficacy. After undergoing scientific validation and reliability tests, this study utilized questionnaires in a descriptive-correlational and causal-comparative research design. Data were gathered from 500 higher education faculty in Northern Mindanao, Philippines. The results revealed a high level of productivity among higher education faculty, particularly in producing instructional tools, engaging in professional development and community service, and a moderately productive level in research and publication. Remarkably, academic heads demonstrated an excellent display of transformational leadership. Higher education faculty exhibited high levels of cultural intelligence and self-efficacy. This implies that the academic head's exemplary display of transformational leadership highlights a commendable commitment to inspiring positive change and fostering growth within the academic setting. Simultaneously, the Higher Education Faculty exhibits remarkable levels of cultural intelligence and self-efficacy, showcasing their proficiency in navigating diverse cultural landscapes and their confidence in their capabilities. Ultimately, the structural model revealed that the productivity of higher education faculty is best explained by the influence of academic heads' transformational leadership, coupled with faculty cultural intelligence and self-efficacy. This model is known as Apdian’s Model of Productivity Among Faculty in State Universities.
