To further improve teaching quality of higher education, the UK government launched Teaching Excellence Framework nationwide from 2017 to 2019. The first round of evaluation has achieved good results in encouraging colleges and universities to provide highquality teaching for students, guiding colleges and universities to improve student experience, and helping high school graduates effectively choose colleges and universities and majors. However, there are still deficiencies in scientificity of index design, reliability and validity of evaluation data, and rationality of result grade setting. Therefore, the new round of Teaching Excellence Framework will further enrich connotation of evaluation indicators, enhance scientificity of evaluation data and improve efficiency of the use of evaluation results. The series of reforms of Teaching Excellence Framework in colleges and universitives of the UK could provide some reference for China to further improve the undergraduate teaching quality evaluation and guarantee system: to attach great importance to teaching quality and strengthen the function of educating people; to highlight students′ perspectives and give consideration to fairness and excellence; to integrate multisource data to enhance scientificity and representativeness of data; to make rational use of evaluation results, and carry out supervision and provide rewards in parallel.
