TOEFL iBT for the United States — Guide for South Korean Students
For South Korean students targeting the United States, TOEFL iBT is one of the most common English tests—but the score you need depends on the institution, program level, and whether visa rules differ from university admission rules. This guide maps requirements so you can find your gap before you retake. Many applicants from India, Nepal, Nigeria, and other major source countries search in English first; the tables below use published university baselines and official destination guides so you can compare options without guessing.
Why your English score matters
US universities, Canada PR, and Australia study all reward a clear English plan. A stronger TOEFL can expand US school lists; CELPIP or IELTS General can unlock Express Entry CLB targets—map the dream before you book. For the United States, discovering too late that your writing or speaking score is below a program minimum can delay an entire intake. Retakes cost time and money—so identifying the controllable bottleneck early is the fastest way to keep more schools and timelines realistically open.

Frequently asked questions
Is TOEFL iBT accepted in the United States for South Korean students?
Many universities and visa pathways in the United States accept TOEFL iBT, but minimum scores vary by institution, program level, and whether you need a student visa or direct admission. Use the requirement table on this page and confirm on each school's official admissions page.
What TOEFL iBT score do South Korean students typically need for the United States?
There is no single national minimum—undergraduate, graduate, and vocational programs publish different scores. The school table below shows published baselines; your target program may require higher section scores.
Can I apply if my TOEFL iBT score is below the requirement?
If your score is below the published minimum, your eligible options shrink quickly. Some schools offer conditional admission or pathway programs, but you should not assume this without checking the official program page.
Should I choose TOEFL iBT or another English test for the United States?
Start with your target program's accepted-test list. If multiple tests are accepted, compare your strongest section profile, test availability near you, and result turnaround time before booking.
How can I check if my current score is enough?
Use the score gap calculator on this page with your section scores, then cross-check the institutions listed below. For visa-specific thresholds, see the official the United States language requirement guide linked from this page. Compare your weakest section against any published per-skill minimum—not only the overall score.
How long should I prepare before retaking TOEFL iBT?
Most students who are within one band or a few TOEFL/PTE points of their target need two to four weeks of focused practice on the weakest section, then one to two full mocks. If your gap is larger, plan six weeks and prioritize writing or speaking if those sections block conditional offers.
Planning reference only—not admission or visa advice. Requirements change—confirm on official university and immigration sources before you apply.
