The Impact of School Leadership Style on Lecturers' Performance at Public Universities in Vietnam

This study assesses the impact of shared leadership behaviors of university leaders on faculty performance, particularly in the context of growing interest in collaborative leadership models to improve organizational outcomes in higher education institutions. Using a quantitative research method, the study used a cross-sectional survey to collect data on leadership behaviors and lecturer performance. The research sample included 800 lecturers from four public universities in Vietnam: National Economics University, Academy of Finance, Banking University of Ho Chi Minh City, and Ho Chi Minh City University of Education. Participants were selected through a convenience sampling method. The author used a scale for shared leadership and lecturer performance , with Cronbach's Alpha reliability coefficients of 0.81 and 0.83, respectively, ensuring internal consistency. Pilot tests confirmed the validity and reliability of the measurement instrument. This study contributes to the literature on shared leadership by providing empirical evidence of its impact on faculty performance in higher education. At the same time, the study also provides practical policy implications for university administrators in applying collaborative leadership techniques to improve organizational effectiveness and faculty productivity.
