General Background: Higher education institutions continuously seek effective approaches to improve educational quality, institutional performance, and stakeholder satisfaction. Specific Background: E-governance and quality cost management have emerged as important mechanisms for supporting administrative efficiency and quality improvement within universities. Knowledge Gap: Although previous studies have examined governance and quality management separately, limited attention has been given to the mediating role of quality costs in the relationship between e-governance and higher education quality. Aims: This study aimed to examine the relationships among e-governance, quality costs, and quality in higher education and to determine the mediating role of quality costs. Results: Data collected from faculty members at the University of Mosul showed significant positive relationships among the study variables. E-governance explained a substantial proportion of variation in higher education quality and quality costs. The findings also revealed that quality costs partially mediated the relationship between e-governance and higher education quality. Novelty: The study integrates e-governance, quality costs, and higher education quality within a single analytical framework in Iraqi universities. Implications: The findings suggest that universities should strengthen e-governance practices, quality assurance systems, staff training, and quality cost management to support continuous improvement and sustainable institutional development.
