This study aimed to analyze the impact of knowledge sharing and its various dimensions (explicit knowledge sharing, tacit knowledge sharing, mutual trust, and collaborative culture) on the performance efficiency of faculty members at the Faculty of Veterinary Medicine and Agricultural Sciences – Al-Ajilat – University of Zawia. The importance of the study stems from the role of knowledge sharing as a contemporary managerial approach that enhances academic and research performance within higher education institutions. The study employed both descriptive and analytical approaches. The population consisted of all faculty members at the college (50 members), using a census method. Data were collected through a questionnaire designed to measure the level of knowledge sharing and performance efficiency and were analyzed using the Statistical Package for the Social Sciences (SPSS). The results indicated that the levels of both knowledge sharing and faculty performance efficiency were moderate, with some deficiencies in tacit knowledge sharing, teaching innovation, and academic collaboration. Furthermore, the results revealed a strong positive and statistically significant correlation between knowledge sharing and performance efficiency (R = 0.820, p < 0.05), confirming the positive impact of knowledge sharing on enhancing faculty members’ performance. The study recommended adopting policies and procedures that support knowledge sharing by developing internal communication channels, fostering a culture of cooperation and teamwork, and providing an academic environment that encourages effective knowledge and experience exchange, thereby contributing to improved academic performance and achieving the college’s objectives.................. Keywords:............... Knowledge sharing, Faculty performance efficiency.
