Abstract : This paper investigates the research design on the management of students’ English learning assessment activities at high schools in the approach of PDCA (Plan, Do, Check, Art). It employed Kumar’s (2011) eight-step format in designing the research process and manipulated Taro’s (1973) formula to calculate its sample size. The sampling for two groups of administrators, teachers of English and students was randomly taken from 10 out of 38 high schools in Tien Giang province, Vietnam. As a result, there were 418 educators and 1829 students chosen, which was much higher than its required sample sizes of 213 administrators, teachers and 397 learners in two groups. Besides, the study exploited a mixed research method to effectively collect quantitative data through questionnaires and qualitative ones through in-depth interviews. Additionally, the study applied SPSS 27.0 software for calculating exploratory factor analysis (EFA), total variance explained and Cronbach’s alpha, and then compared them with three accepted values of 0.3, 50.0% and 0.7, accordingly, for confirming their connection and reliability within each group. The findings indicate that all items in questionnaires met the requirements in this research.
