Middle school grades in Korea play a crucial role not only in high school admissions but also in establishing foundational study habits. As of 2026, Korean middle schools use an achievement-based absolute grading system with five levels from A to E. This guide explains the grading system and provides strategies for managing grades and preparing for high school admissions.
We cover the relationship between the free semester program and grades, and how different types of high schools evaluate middle school performance.

Achievement Grade System (A-E)
Korean middle schools use absolute grading (achievement-based evaluation), not relative grading. Grades are determined by fixed score ranges, not by class ranking.
| Grade | Score Range | Meaning |
|---|---|---|
| A | 90 and above | Excellent |
| B | 80 - 89 | Good |
| C | 70 - 79 | Average |
| D | 60 - 69 | Needs Improvement |
| E | Below 60 | Significant Improvement Needed |
Since it's absolute grading, grades are determined solely by individual scores, not class rank. Theoretically, every student in a class could receive an A grade.

During the free semester (typically 1st semester of 7th grade), students do not take midterm or final exams, and no achievement grades are issued. These grades are not reflected in high school admissions, making 8th and 9th grade grades especially important.
High School Admissions by Type
Assigned by residence — grades aren't a direct admission factor, but still important for academic readiness.
Comprehensive evaluation of grades + attendance + self-introduction + interview. Multiple A grades in key subjects required.
School-specific criteria. Generally requires A grades across all subjects with interview and personal statement.
Grade Management Strategies
Even during the free semester, build a strong academic foundation that carries into 8th grade.
This is when grades start counting for admissions. Aim for A grades in all major subjects.
Performance assessments account for 40-60% of the total grade in middle school — they matter as much as written exams.
