South Korea uses a nationally coordinated 6-3-3 school structure: six years of primary school, three years of middle school, and three years of high school, followed by several forms of higher education. Primary and middle school together form the nine-year compulsory period. The Ministry of Education sets the national curriculum and major education rules, while 17 metropolitan and provincial offices of education administer schools locally. The latest 2026 education statistics counted 5.36 million students across kindergarten, primary, middle, high, and other school types, down 3.4% from 2025. [KEDI]

Structural Overview of the Korean Education System
The basic school route follows the 6-3-3 pattern. Six years of primary school and three years of middle school are compulsory. High school lasts another three years but remains outside the legal compulsory period. Postsecondary routes include junior colleges, universities, graduate schools, cyber universities, and other specialized institutions.
| Educational Stage | Grade Level | Typical Age | Status |
|---|---|---|---|
| Primary Education | Grades 1–6 | About 6–12 | Compulsory |
| Middle School | Grades 7–9 | About 12–15 | Compulsory |
| High School | Grades 10–12 | About 15–18 | Not legally compulsory |
| Higher Education | Variable | Usually 18/19+ | Optional |
The academic year begins in March and normally ends the following February. Korea’s 2022 revised national curriculum is being phased in by grade. It began with Grades 1–2 in primary school in 2024, expanded to primary Grades 3–4, middle-school Grade 1, and high-school Grade 1 in 2025, and reached primary Grades 5–6, middle-school Grade 2, and high-school Grade 2 in 2026. The remaining middle- and high-school grades are scheduled to follow in 2027. [MOE]
Early Childhood Education and Care
Korea has historically operated kindergartens and childcare centers under separate legal and institutional systems. That administrative structure began changing on June 27, 2024, when responsibility for early-childhood education and childcare was consolidated at national level under the Ministry of Education as part of the Yubo-tonghap integration process. Kindergartens and childcare centers still retain different institutional arrangements while the integration work continues. [MOE]
Children aged 3–5 use the common Nuri Curriculum, while the national childcare curriculum for ages 0–2 was revised from March 2025 to place more emphasis on learning through play and stronger continuity with the Nuri Curriculum. Early-childhood education is not part of the nine-year compulsory-school period. [Government of Korea]
Primary Education
Primary school lasts six years and focuses on Korean language, mathematics, ethics, social studies, science, arts, physical education, practical learning, and other curriculum areas. English begins from Grade 3. The 2022 revised curriculum also strengthens digital literacy, information education, student choice, inquiry, and links between school transitions and career learning.
Demographic change is now visible in school statistics. In 2026, primary-school enrollment fell to 2,219,370 students, down 126,118 from 2025. Average primary class size decreased from 19.3 students in 2025 to 18.6 in 2026. [KEDI]

| Stage | Students | Change from 2025 |
|---|---|---|
| Kindergarten | 469,304 | −12,259 |
| Primary school | 2,219,370 | −126,118 |
| Middle school | 1,338,750 | −31,606 |
| High school | 1,279,392 | −20,074 |
All four major stages recorded lower student numbers in 2026. Primary education experienced the largest absolute decline, accounting for about two-thirds of the combined reduction across kindergarten, primary, middle, and high school. This differs from 2025, when middle-school enrollment had still been rising as larger cohorts moved through the system.
Middle and High School
Middle School and the Free Semester
Middle school covers Grades 7–9 and completes the compulsory cycle. The Free Semester policy reduces conventional written testing during a designated period and gives more space to discussion, projects, career exploration, arts, sports, and experiential learning. The 2022 revised curriculum retains the Free Semester while adjusting its operation and adding transition-oriented career learning around changes between school levels.
High School Types
High school lasts three years. The system includes general high schools, special-purpose high schools, specialized vocational schools, Meister high schools, and autonomous schools. These categories differ in curriculum emphasis, admissions, institutional mission, and links to university or employment.
- General high schools: broad academic programs with a strong pathway toward university admission.
- Special-purpose high schools: specialized programs in areas such as science, foreign languages, international studies, arts, or physical education.
- Vocational and specialized high schools: occupation-linked education in technical, commercial, agricultural, service, and other fields.
- Meister high schools: industry-linked vocational schools designed around skilled technical employment and sector needs.
- Autonomous high schools: schools with additional curricular or operational discretion within national rules.
The revised high-school curriculum is moving further toward a credit-based model with broader student subject choice. This transition is being phased in alongside the 2022 revised curriculum rather than replacing all high-school requirements at once.
College Scholastic Ability Test (CSAT)
The College Scholastic Ability Test, or Suneung, remains one of the main national instruments used in university admission. The 2027 academic-year CSAT is scheduled for November 19, 2026, with results due on December 11. The examination covers Korean, mathematics, English, Korean history, inquiry subjects, and an optional second foreign language or Classical Chinese section. Korean history is compulsory. [MOE/KICE]
CSAT reporting is more varied than a single percentile ranking. Korean, mathematics, and inquiry results use standard scores, percentiles, and grade bands, while English and Korean history use absolute grade bands. Universities then apply their own combinations of CSAT scores, school records, interviews, essays, or other admission components. For the 2027 examination, EBS-linked material remains indirectly connected to about 50% of questions by item count. [KICE]
PISA 2025: International Learning Outcomes
Korea remained among the highest-performing education systems in PISA 2025. Fifteen-year-olds averaged 522 in mathematics, 501 in reading, and 526 in science, compared with OECD averages of 463, 461, and 482. Korea also scored 538 in computational problem solving, compared with the OECD average of 500. [OECD PISA]

Unit: PISA score points. OECD reports the 2022–2025 changes as statistically stable in mathematics and science, with a decline in reading.
Mathematics and science remained close to their 2022 levels, while reading declined. OECD reports a 2022–2025 change of about −5 points in mathematics, −15 in reading, and −2 in science. Compared with 2015, mathematics and science remained broadly stable, while reading was lower. [OECD PISA]
| Domain | Korea: Level 2+ | OECD Average: Level 2+ | Korea: Level 5 or 6 |
|---|---|---|---|
| Mathematics | 81% | 65% | 23% |
| Reading | 82% | 69% | 10% |
| Science | 86% | 74% | 15% |
The proficiency distribution remained strong. Korea’s Level 2-or-higher share exceeded the OECD average by 16 percentage points in mathematics, 13 points in reading, and 12 points in science. Nearly one-quarter of Korean students reached Level 5 or 6 in mathematics, one of the highest shares among participating systems. [OECD PISA]
Higher Education
Korea continues to record the highest tertiary-attainment rate among OECD countries for young adults. In 2024, 70.6% of 25–34-year-olds had completed tertiary education, compared with an OECD average of 48%. The share was 63.7% among men and 78.2% among women. [OECD]
The 2026 education census counted 416 higher education institutions and 3,072,261 enrolled students. The system includes general universities, universities of education, junior colleges, graduate universities, cyber universities, and other institution types. The number of higher education institutions fell by five from 2025, while total enrollment rose by 1.8%. [KDI/KEDI]
The high level of degree attainment does not translate into an equally high employment rate for every young graduate. OECD data place the employment rate of tertiary-educated 25–34-year-olds at about 80%, below the OECD average of 87%. The gap helps explain why higher-education policy now addresses graduate employment and regional university sustainability alongside participation itself. [OECD]
Private Education and Hagwons
Private tutoring remains a large parallel market for elementary, middle, and high school students. The latest 2025 survey recorded KRW 27.5 trillion in private-education spending, down 5.7% from the record KRW 29.2 trillion in 2024. Participation fell from 80.0% to 75.7%, while weekly participation time declined from 7.6 to 7.1 hours. [MOE]
Private Education Spending

| Indicator | 2024 | 2025 | Change |
|---|---|---|---|
| Total private-education spending | KRW 29.2 trillion | KRW 27.5 trillion | −5.7% |
| Participation rate | 80.0% | 75.7% | −4.3 percentage points |
| Weekly participation time | 7.6 hours | 7.1 hours | −0.5 hour |
| Monthly average per all students | KRW 474,000 | KRW 458,000 | −3.5% |
| Monthly average per participating student | KRW 592,000 | KRW 604,000 | +2.0% |
The 2025 decline in total spending occurred while the average cost among students who still used private education increased. Elementary-school participation remained the highest at 84.4%, followed by middle school at 73.0% and high school at 63.0%. The figures also reflect a shrinking student population: the survey population fell from 5.13 million in 2024 to 5.02 million in 2025. [MOE]
Teacher Workforce and School Transfers
Public-school teachers are employed within metropolitan and provincial education-office personnel systems. Recruitment, appointment, promotion, and transfers operate under national and local personnel rules. Periodic transfer between schools is used in many public systems, but there is no single nationwide 3-to-5-year transfer rule that applies identically to every teacher and principal; transfer cycles and exceptions differ by education office, position, school level, and local personnel policy.
The 2026 education census counted 505,545 teachers across kindergarten, primary, middle, high, and other school types. The total declined slightly from the previous year, while the number of students fell more rapidly. As a result, the number of students per teacher decreased across all reported school levels. [KDI/KEDI]
International Students and Study Korea 300K
The Study Korea 300K Project, announced in 2023, set a target of attracting 300,000 international students by 2027. The target was reached early. The 2026 education census counted 307,464 international students in Korean higher education, up 21.3% from 253,434 in 2025. [MOE] [KEDI]

| 2025 | 253,434 | +21.3% |
| 2026 | 307,464 | +21.3% |
Degree-program students accounted for 223,191 of the 2026 total and non-degree students for 84,273. China represented the largest share of degree-program international students, while Vietnam accounted for the largest share of non-degree students. The growth means the numerical target of Study Korea 300K was passed one year before its original 2027 deadline.
Education Budget and Funding
The Ministry of Education’s 2026 budget was finalized at KRW 106.36 trillion. Spending priorities included regional universities, artificial-intelligence talent development, early-childhood education and childcare integration, and other national education programs. In April 2026, a separate first supplementary education budget of KRW 4.81 trillion was approved; it included additional local education grants and measures related to employment support and education-sector operating costs. [MOE] [MOE]
Demographic change is affecting how resources are distributed. Between 2025 and 2026, the school-age education census lost 189,007 students, while higher-education enrollment increased. Funding debates therefore concern regional university capacity, early-childhood services, digital education, workforce needs, and the distribution of local school resources rather than simple system expansion.
Digital Education and AI Learning Materials
Korea began using AI-based digital learning materials in selected grades and subjects in 2025. The original rollout covered English and mathematics in primary Grades 3–4, middle-school Grade 1, and high-school Grade 1, with informatics included at middle and high school. The legal status of these products then changed. [MOE]
Under amendments promulgated on August 14, 2025, AI-enabled learning-support software is treated as educational material rather than a textbook. Schools selecting such software must follow Ministry of Education criteria and obtain review through the school operating committee. The law also states that learning-support software cannot be approved as a textbook under the textbook provisions. [Korean Law]
The wider AI-education policy continued after that legal change. In March 2026, the Ministry of Education selected 1,141 AI-focused elementary and secondary schools to expand AI literacy, curriculum models, responsible use, and teacher capacity. This is separate from the earlier policy of treating AI digital products as nationally recognized textbooks. [MOE]
