Rank percentile calculation method
Internal school grades are determined by percentile rank. To calculate an accurate percentile rank, students with the same rank must be included.
Rank percentile formula
Rank Percentage (%) = (Rank + Number of Ties – 1) ÷ Total Enrollment × 100
GPA Standards Table (2026)
Grade 1 ≤ 4% < Grade 2 ≤ 11% < Grade 3 ≤ 23% < Grade 4 ≤ 40%
Grade 5 ≤ 60% < Grade 6 ≤ 77% < Grade 7 ≤ 89% < Grade 8 ≤ 96% < Grade 9
Grade 5 ≤ 60% < Grade 6 ≤ 77% < Grade 7 ≤ 89% < Grade 8 ≤ 96% < Grade 9
Example) 10th place out of 300 total, 3 tied: Rank Percentage = (10+3-1)÷300×100 = 4.0% → Grade 2
Frequently Asked Questions
What is a same-ranking position?
This is the number of students who received the same score and rank. Please include yourself in this entry. If there are no ties, please enter 1.
Are the grading standards for the CSAT and GPA different?
Yes, they are different. School grades are graded from 1 to 9 based on percentile rank, while standard scores, percentiles, and grades for the CSAT are calculated separately.
How is the Grade 1 cutoff rank calculated?
Grade 1 is based on a percentile rank of 41 TP3 T or lower, so a rank of 0.04 or less of the total number of people is Grade 1. If there are 300 people in total, the top 12 are Grade 1.
