Korea curriculum

Overview

South Korea's school system runs on a 6-3-3 structure under the Ministry of Education: 6 years of elementary school, 3 years of middle school, and 3 years of high school, followed by university or junior college. Elementary and middle school together make up 9 years of compulsory, tuition-free education; high school is not compulsory and charges fees, though most students attend it. Schools nationwide follow one national curriculum set by the Ministry of Education, most recently updated by the 2022 Revised National Curriculum. University admission is decided largely by the College Scholastic Ability Test (CSAT, also called Suneung), a separate gatekeeping exam sat at the end of high school and covered in its own programme file; this file covers the school structure, the national curriculum, and day-to-day assessment that leads up to it.

Who it covers

Every child in South Korea must complete the 9-year compulsory stage: 6 years of elementary school followed by 3 years of middle school, both free of tuition. Children typically start elementary school at age 6 (in the calendar year they turn 8 by the Korean age-counting convention used in official guidance, i.e. around age 6 in international terms) and finish middle school around age 15. High school, covering roughly ages 15 to 18, is not compulsory and is not free, but the great majority of middle school graduates go on to it, choosing between a general academic high school, a specialised high school (such as a foreign-language or science-focused school), or a vocational (meister) high school.

Structure

Elementary school

Six years of compulsory schooling covering Korean language, mathematics, social studies, science, English (from grade 3), art, music, physical education, and practical/moral education, taught to the Ministry of Education's national curriculum. The academic year runs from March to February, split into two semesters, with the first semester starting in March and the second starting at the end of August.

Middle school

Three years continuing compulsory education at a deeper level, with subjects assessed through a mix of school exams and, in many schools, a "free semester" period in grade 1 that replaces formal written exams with project- and activity-based assessment. Middle school ends with graduation into high school; there is no single national gatekeeping exam comparable to the CSAT at this stage, and admission to most high schools is managed locally rather than through one nationwide test.

High school

Three years split between general academic high schools, specialised high schools (for example, foreign languages, science, or the arts), and vocational (meister) high schools. From 2025, all high schools run under the high school credit system, in which students earn credits toward graduation by choosing from an expanded set of elective subjects aligned to their intended career path, rather than following one fixed timetable for every student. High school ends with the CSAT for students applying through the main university admission track; the CSAT's own subjects, timing and scoring are covered in its own programme file.

Curriculum standards

The Ministry of Education sets one national curriculum that applies to every elementary, middle and high school in the country; individual schools do not set their own separate syllabus. The current version is the 2022 Revised National Curriculum, confirmed in December 2022, which began phasing in from elementary schools in 2024 and high schools in 2025. It increases instructional time for Korean-language and digital/AI literacy in the early elementary grades, introduces play-based learning approaches for grades 1-2, and adds emphasis on ecological-transition and democratic-citizenship education across all stages. The 2022 revision is also the curriculum basis for the high school credit system, which restructures how high school subjects are organised and chosen from 2025 onward.

Assessment approach

Day-to-day assessment in Korean schools is continuous and school-based, separate from the CSAT. Elementary schools assess students through classroom-based observation and periodic school exams rather than high-stakes testing. Middle schools combine written exams with performance assessment, and many run a free-semester term, usually in grade 1, where formal exams are replaced by project work, discussion, and career-exploration activities.

High schools record each student's subject grades, attendance, and activities in an official School Life Record, which universities use alongside, or instead of, the CSAT for admission depending on the admission track. Early admission tracks (available before the CSAT is held) weigh the School Life Record, along with recommendations, personal statements, or interviews, more heavily; regular admission tracks (held after the CSAT) weigh the CSAT score itself as the primary criterion. Under the high school credit system introduced from 2025, a student's choice and completion of elective credits also feeds into this record.

After school

Completing middle school is what allows a student to move on to high school; completing high school and, for most students, sitting the CSAT is what decides admission to university or junior college. The CSAT is the national university entrance exam, covered separately in its own programme file, including its subjects, format, and how its score is used across Korea's early- and regular-admission tracks.

Preparation tips

• Confirm which type of high school (general, specialised, or vocational/meister) fits a student's intended path before middle school graduation, since the choice shapes the subjects available afterward.

• Treat the School Life Record as something built up over all three years of high school, not just the final year, since early-admission tracks weigh it heavily alongside, or instead of, the CSAT.

• Under the high school credit system, plan elective-subject choices around the student's intended university major or career path, since credits are now chosen rather than fixed for everyone.

• Separately research the CSAT's own subjects and timing well before the final year of high school, since it is covered in its own programme file and remains central to the regular admission track.
