With the popularization of higher education in China, the main body of quality assurance has shifted from government and other external evaluation bodies to universities themselves. To promote this, the Ministry of Education actively encourages universities to build and improve their internal quality assurance systems through a new round of audit and evaluation. How to establish an effective internal quality assurance system for undergraduate education and teaching within the existing internal governance models of universities is a common issue faced by university administrators today. This paper uses Shenyang Pharmaceutical University as an example to introduce the path of constructing its internal undergraduate education and teaching quality assurance system.
