🇰🇷 South Korea GPA Converter

South Korea uses a GPA-based grading system at all universities. The two most common scales are the 4.5 scale — used by the majority of Korean universities including Seoul National University (SNU), Korea University, Yonsei University, Hanyang University, and Sogang University — and the 4.3 scale used by Sungkyunkwan University (SKKU), KAIST, Ewha Womans University, and POSTECH. Korean grades are recorded as GPA and CGPA values using a system of letter grades.

The Korean letter grade system uses A+, A0, B+, B0, C+, C0, D+, D0, and F — where A+ = 4.5 (or 4.3), A0 = 4.0, B+ = 3.5, B0 = 3.0, C+ = 2.5, C0 = 2.0, D+ = 1.5, D0 = 1.0, and F = 0.0 regardless of scale. The use of A+ and A0 rather than A and A− is a distinctive feature of the Korean system that differs from both the US and European grading conventions. Korean grades are equivalent to Credit Hours to ECTS Converter in that they use a similar academic credit structure.

The minimum passing grade is D0 (1.0) at most Korean universities, though academic standing requirements for continued enrolment are typically higher — most universities require a minimum C0 (2.0) cumulative GPA to remain enrolled without academic probation. Some competitive programmes have even higher minimum GPA requirements for continued enrolment.

Korean universities — particularly the SKY universities and top technical institutions — are known for highly competitive grading environments. Grade distributions at many institutions are controlled by mandatory relative grading policies (상대평가 — relative evaluation) which limit the proportion of A grades that can be awarded in any given course, typically to no more than 30% of enrolled students. This means Korean GPAs are often systematically lower than equivalent performance in curve-free grading environments and international evaluators should always consider this important context. Korea uses a credit system (학점) broadly comparable to the US credit hour system — see the Credit Hours to ECTS Converter for credit equivalencies across different education systems.

The SKY universities — Seoul National University (SNU), Korea University, and Yonsei University — are South Korea's three most prestigious universities and are well-recognised internationally, particularly in engineering, business, law, medicine, and social sciences. SNU is consistently Korea's highest-ranked university globally and is well-known to US admissions committees — SNU graduates are competitive for US and European graduate programmes across multiple disciplines. Korea University and Yonsei University are similarly prestigious private universities with strong international recognition and large alumni networks among Korean international students in the USA.

KAIST (Korea Advanced Institute of Science and Technology) in Daejeon is Korea's premier science and technology research university — modelled in part on MIT, it conducts all instruction in English for its graduate programmes and produces graduates who are highly competitive for US STEM PhD programmes. KAIST's official website at kaist.ac.kr provides full details on admissions, degree programmes, and research facilities. KAIST graduates in computer science, electrical engineering, and materials science are regularly admitted to top US PhD programmes at MIT, Stanford, Carnegie Mellon, and other leading institutions.

POSTECH (Pohang University of Science and Technology) is another elite science and technology university with a strong research focus and excellent international recognition in engineering and sciences. Korean graduate students in engineering, computer science, and natural sciences are well-represented in US PhD programmes, and Korean academic training in these fields is highly regarded by US admissions committees. Korean students in STEM PhD programmes at US universities typically fund their graduate study through research assistantships rather than external scholarships.

The Korean relative grading system (상대평가 — sangdae pyeongga) is one of the most important contextual factors for international evaluation of Korean transcripts. Under this system Korean universities — particularly the SKY universities and other competitive institutions — limit the percentage of students who can receive A grades per course, typically to 30 to 35 percent of enrolled students. This means that even an excellent student in a competitive cohort may receive B+ or B0 grades simply because the quota of A grades has been filled by peers who scored marginally higher — not because their performance was inadequate by absolute standards.

This mandatory relative evaluation produces systematically lower GPA distributions at Korean universities compared to US universities that use absolute grading. A Korean student with a 3.5 GPA on the 4.5 scale from SNU is performing at a higher relative level within their cohort than the raw number suggests when compared to a student with a 3.5 GPA from a US institution using pure absolute grading. The competitive academic environment at Korean universities — where students are often competing against extremely well-prepared peers who have completed intensive preparatory study — further amplifies this effect.

US admissions committees at institutions that regularly admit Korean students are generally aware of this system. Korean students applying to US programmes should note in their application that their university uses mandatory relative grading and may include a brief explanation of this system in the additional information section of their application. Some Korean universities provide a grading policy document (성적 분포표) on request which shows the grade distribution for each course — this document can be a useful supplement to the official transcript for US graduate applications.

WES (World Education Services) evaluates South Korean credentials from universities accredited through the Korean Ministry of Education and uses conversion tables specifically calibrated for both the 4.5 and 4.3 GPA scales, accounting for Korean grading culture including the relative grading system. WES is the most widely accepted credential evaluation service for Korean graduates applying to US institutions. Use the WES GPA Calculator to estimate your WES-equivalent GPA before requesting your formal evaluation. WES evaluations typically take four to seven weeks for standard service and eight to ten business days for rush service. wes.org

To request a WES evaluation, Korean students must have their official academic transcript (성적증명서 — seongjeok jeungmyeongseo) sent directly from their university's academic registry to WES. WES does not accept transcripts submitted by the applicant. Korean transcripts are typically issued in both Korean and English — WES accepts the English-language version directly from the issuing institution. The transcript must bear the official university seal and be sent in a sealed envelope or transmitted via WES's secure institutional submission system.

The Korean Ministry of Education (교육부) and the Korean Institute for Curriculum and Evaluation (KICE) oversee higher education standards in South Korea. WES verifies institutional accreditation through the Korean Ministry of Education registry — all major Korean universities including the SKY universities, KAIST, POSTECH, and all other national and private universities are listed in this registry and are recognised by WES. WES provides both document-by-document evaluations and course-by-course evaluations — US graduate schools typically require the more detailed course-by-course evaluation.

Most US graduate programmes require a minimum GPA equivalent of 3.0 on the US 4.0 scale. For Korean students on the 4.5 scale, this corresponds to a Korean GPA of approximately 3.0 to 3.3, depending on the specific conversion table applied. For students on the 4.3 scale, a Korean GPA of 3.0 approximately corresponds to a US GPA of 3.0. Use the University Match Calculator and College Admission Chance Calculator to understand your competitiveness for specific US graduate programmes.

Korean students with a Korean GPA of 3.5 and above on the 4.5 scale from SKY universities, KAIST, or POSTECH are generally competitive for strong US graduate programmes. Korean students are among the most numerous international student groups in the United States — particularly in STEM PhD programmes — and Korean academic training is highly regarded by US admissions committees in engineering, computer science, natural sciences, and business. The relative grading context should be communicated in applications — Korean students from institutions with mandatory relative grading should note this in the additional information section of their graduate applications.

English language requirements are mandatory for US graduate applications from Korean students. Most US graduate programmes require a minimum TOEFL iBT score of 80–100 or IELTS band of 6.5–7.0, with competitive PhD programmes often requiring higher scores. Use the TOEFL Score Calculator and IELTS Band Calculator to understand your score requirements. Students from KAIST's English-medium programmes may be eligible for English proficiency waivers at some US institutions — verify this with each programme individually.

UK universities typically convert Korean GPA grades using the following general equivalence: Korean GPA 4.0 to 4.5 on the 4.5 scale corresponds to a First Class Honours equivalent; 3.3 to 3.9 corresponds to an Upper Second Class (2:1) equivalent; 2.7 to 3.2 corresponds to a Lower Second Class (2:2) equivalent; and 2.0 to 2.6 corresponds to a Third Class equivalent. Use the UK University Grade Calculator and the UK Grades vs US Grades comparison for a full breakdown of these equivalences.

Most UK Master's programmes require a minimum 2:1 equivalent for postgraduate entry, meaning Korean students typically need a GPA of approximately 3.3 and above on the 4.5 scale for competitive UK postgraduate consideration. Some UK research programmes and competitive taught Master's programmes at Russell Group universities may require a First-class equivalent (4.0+ on the 4.5 scale). UK universities also apply their own contextual assessment of Korean grades and are generally aware of the relative grading system at major Korean universities — Korean students are encouraged to note this context in their personal statement or supporting documents.
