"Is School District Disadvantageous for Internal Grades? Opposing the Structure"

More Than 300 Students Per Grade Concentrated in Yangcheon, Seocho, and Gangnam
Three Seoul High Schools With Fewer Than 100 Students Each Located in Seongbuk, Gwanak, and Yongsan
"More Students Make It Easier to Achieve Top School Records"

'School district area = CSAT, Non-school district area = School records'

It has been recognized that different admission types are advantageous depending on the region during college entrance, but an analysis showing that school records are also advantageous in school district areas has drawn attention. The key factor is 'number of students.'

On the 10th, Jongno Academy investigated the distribution status of student numbers in general high schools in Seoul for the 2026 academic year. The result showed that regions with an average of over 300 students per grade (based on current 3rd-year high school students) were concentrated in three districts commonly referred to as school district areas: Yangcheon, Seocho, and Gangnam.

In Yangcheon-gu (11 schools), the average number of students per grade was 325.4, the highest among the 25 districts. Seocho-gu (8 schools) had 316.5 students, and Gangnam-gu (14 schools) had 304.5 students.

On the other hand, districts such as Gwanak-gu (12 schools, 194.8 students), Jongno-gu (7 schools, 178.6 students), Seongdong-gu (5 schools, 161.6 students), Jung-gu (3 schools, 161.0 students), and Yongsan-gu (7 schools, 150.6 students) had student numbers per grade in the 100s.

Some schools in certain areas have fewer than 100 students. One school in Seongbuk-gu had 88 third-year students, Gwanak-gu had 84, and Yongsan-gu had 95.

Having fewer than 100 students in one grade means that obtaining high school records is correspondingly difficult.

Under the current 9-grade school record system, to receive a 1st grade, a student must be in the top 4%. The 2nd grade is up to 11%, 3rd grade 23%, 4th grade 40%, 5th grade 60%, 6th grade 77%, 7th grade 89%, 8th grade 96%, and 9th grade 100%. When there are 100 students in the entire school, the calculation shows that the top 4 students receive 1st grade. However, in elective subjects, the number of students taking the course is divided, so if only 1 to 4 students take the subject, no one can receive 1st grade. This means that regardless of student ability, entering the 1st grade may be impossible.

Lim Seong-ho, CEO of Jongno Academy, said, "Generally, it is thought that school district areas are disadvantageous for getting good school records due to fierce competition, so studying in non-school district areas is advantageous for school records, but structurally, the opposite is true."
