Studies have been conducted to determine the impact of English language on the academic achievement of international students in higher education institutions in the United States. The results of these investigations have been varied and at times contradictory. The purpose of this meta-analysis was to investigate studies from 1987-2009 that examined the correlation between the Test of English as a Foreign Language (TOEFL) on grade point average (GPA) and course completion. The results indicated that the TOEFL has a small predictive ability on GPA and course completion of international students at both the undergraduate and graduate levels. The findings are useful for university admissions offices and academic departments responsible for admissions decisions for international students.
