South Korea is known for its high-performing education system and strong academic outcomes. However, these achievements are often linked to the country’s highly competitive academic culture and the significant pressure placed on students. These eight facts examine South Korea’s education system and the realities students face within its rigorous learning environment.

8 Facts about Education in South Korea

1. Even though education is mandatory through age 15, a shrinking population is currently altering the landscape. Since 2021, the number of registered students fell from 5.32 million to approximately 5.01 million during the 2025/2026 period. Consequently, more than 150 campuses have shut down permanently over the past five years. Nevertheless, participation remains near 100%, and authorities are utilizing lower student-teacher ratios — roughly 13.7 to 1 within elementary schools — to offer more tailored instruction.
2. South Korea places high emphasis on early learning. Through the “Nuri Curriculum,” the state provides childcare and schooling for all children aged 3 to 5 years old and financial support if needed. Participation in these early programs surpasses 90%, with private preschool options being preferred due to the quality and hours of such programs. The Nuri Curriculum emphasizes physical, cognitive and social development through play.
3. As of 2025, South Korea pioneered the use of AI-enabled digital books for English, mathematics and computer science. These automated teaching assistants customize lessons instantly, allowing pupils to move through material at a speed that suits them. This recent milestone represents a pivot away from uniform learning toward digital fluency and individual mastery.
4. Moral instruction plays a crucial part in the foundation of education in South Korea. The syllabus for younger children continues to feature “Good Life” as well as “Wise Life” segments, which help children adjust to life in school. Later, students study morality in conjunction with social studies to reinforce the importance of ethics in their community and the world.
5. In addition to public schools, hagwons —  private tutoring institutions — play a large role in students’ education as well. Approximately 78.3% of students across education levels participate in Hagwons, which comprise an industry worth over $20 billion. Although the government has tried to put restrictions on Hagwons to prevent them from going overboard, such as imposing a “Hagwon curfew” of 10 PM, students and their families are so determined to receive the preparation they need to attend university that these restrictions have not always been successful.
6. Despite high scores, stress among students persists. Self-harm remains the primary reason for teenage mortality across the country, with a significant contributing factor being academic stress. To address this problem, South Korea offers services for mental health, including therapy, school-based help and medical care. In 2018, 5 million teenage South Korean students sought out counseling.
7. In current PISA assessments, South Korea remains in the top five nations, with consistent performance across science, mathematics and reading. In both 2022 and 2026, South Korea had the fifth-highest PISA score in the world, scoring sixth in math, fifth in science and fourth in reading in 2022. South Korea’s strong performance on international standardized tests proves the efficacy of its educational system.
8. To discourage “hyper-competition,” the state is moving high school assessments from a nine-level scale to a five-level format. By increasing the “top rank” (Tier 1) to cover 10% of pupils—up from the previous 4%—the policy seeks to dampen aggressive GPA rivalry. Furthermore, South Korea recently changed the Suneung, the college entry exam, consolidating the topics to “ensure fairness and stability”. These means of academic reform will hopefully make assessments of students more fair.

This overview highlights the large emphasis that South Korea places on education. While the nation remains an intellectual powerhouse, it should perhaps take the emotional needs of its youth into account and take steps to reduce stress. Through the adoption of AI and more fair grading, South Korea aims to continue to improve its education system and ensure that it progresses on par with the world around it.
