However, in Vietnam, not much research has attempted to investigate in an in-depth manner as to what are the problems, causes, and consequently the suggestions of such a notion. The research hence aims to investigate the phenomenon in a more thorough, empirical manner. To this end, the study employed the participation of 205 IELTS learners from two language centers in Ho Chi Minh city to provide their opinions regarding the problems, causes, and recommendations deemed the most pressing, acute, and beneficial, respectively. With convenience sampling and survey being the chosen research design, the research was quantitative in nature, producing numerical data as a result. Further analysis conducted via comparing the means of the items listed in the questionnaire yielded based on the IELTS band descriptors managed to discover a series of problems, causes, and suggestions considered the most relevant to the Vietnamese learners concerning IELTS writing task 2. The research thus served as the basis for teachers and learners of IELTS writing task 2 to identify the recurrent issues and provide relatable approaches.
