Amidst the deepening reform of higher education, the new round of undergraduate teaching and learning audit-evaluation offers medical universities a timely opportunity to re-engineer their teaching-quality assurance systems. Grounded in the core requirements of the audit-evaluation framework, this study systematically diagnoses the prevailing weaknesses in current quality-assurance regimes of medical schools and proposes targeted optimisation strategies. The findings demonstrate that refining the quality-standard architecture, upgrading the quality-monitoring mechanism and reinforcing a continuous-improvement loop can substantially enhance medical-education quality and cultivate high-calibre professionals aligned with societal needs.
