English Language Proficiency (ELP) plays a crucial role in shaping the academic outcomes of international students. This research, examines the relationship between language proficiency and academic performance among the international students. As English is the medium of instruction in universities, a good command of English is essential for effective learning and academic attainment. Quantitative research methodology will be employed to collect data from 132 international students studying at various universities in the Delhi NCR, India.
The findings reveal ELP scores of most students are ranged between beginner and intermediate level. This suggests that most students have difficulties in understanding lectures, participating in class discussion, and academic writing. There is a significant relationship between the ELP levels and academic success (r = 0.623, p < 0.001). The R² shows that the English language proficiency accounts for about 39 percent of the variance in academic performance (R² ≈ 0.388). While overall effectiveness can be considered limited, the institution's proposed solution can be characterized as moderately effective.
