Please note that this section refers to the percentage of students in each year whose English language proficiency level meets B2 or C1 and above.
We use the “CEFR” framework to determine student English language proficiency and the skills assessed in reading, listing, writing, and speaking. The table below illustrates the overall language proficiency level for the 107th academic years. The Center for English Education placed students into different proficiency levels according to their college entrance exam scores. Students would be suggested to take English courses in the appropriate groups.
