South Korean school system

The South Korean school system is divided into elementary school, middle school, high school, and university. Six years of elementary school and three years of middle school education are compulsory. When students enter middle school, the level of happiness decreases sharply due to the full-fledged university entrance examination process. In general, students will wear uniforms starting from middle school, with restricted clothing and hair style.

The total number of schools at all levels in South Korea, from kindergarten to graduate school, was over 20,000 in 2023. In recent years, the number of students per class in schools across all levels has significantly decreased due to continued lower birth rates. For example, the number of students per class in middle schools fell from 38 in 2000 to 24.6 in 2023. The South Korean school year consists of two semesters; the Spring semester from March to June and the Fall semester from September to December, with graduation in February.

In 2023, around 78.5 percent of Korea's primary and secondary students participated in private education.
