This review article begins with a brief overview of what an English language teaching (ELT) evaluation system is, and then analyzes the current state of the English language teaching evaluation system in Chinese universities in the context of COVID-19. At the same time, this review article expounds how to better establish a good evaluation system for English language teaching in the context of COVID-19 as well as for the English language studies and its application in language teaching practices in Chinese universities. Based on a series of literature analysis, the current review article has come to such a conclusion that in the context of COVID-19, the division of stages before, during and after class is relative. Therefore, the methods and means of using the formative evaluation system and the summative evaluation system are not separate and independent. It is because both formative and summative assessment systems are diagnostic in nature. The summative evaluation system has the nature of the formative evaluation system, and no formative evaluation system is an incomplete evaluation system.
