Abstract
This study aimed to clarify the characteristics of the reading comprehension process of one non- learner of Sino Vietnamese words among Vietnamese candidates who passed the national examination for care workers. The results of the study suggested that non-learners of Sino-Vietnamese words had difficulty in accurately understanding the text of the national exam for care workers, as they were unable to guess the meaning of the words using Sino-Vietnamese words compared to learners of Sino-Vietnamese words.
