Once a student decides to leave school, the first practical obstacle is knowing when the equivalency exam can actually be taken. You cannot sit it the month after withdrawing. There is a waiting period built into the eligibility rules, and because the cut-off date is not the exam date, families frequently lose an entire sitting.

Six months after removal — measured from the announcement date, not the exam

Anyone with middle school graduation status may sit the high school equivalency exam. If you attended high school and then left, however, one further condition applies. Six months must have passed between the date of removal from the register and the announcement date.

The point people get wrong most often is the announcement date. The six months are counted not to the day of the exam but to the day the metropolitan or provincial office of education publishes the plan for that sitting. Announcements typically come more than two months before the exam, so counting to the exam date makes it look as though you have an extra two months of room.

The actual announcement states this as a fixed date: anyone removed from the register after a given day cannot apply. Finding that one line first is the quickest way to settle the question.

There are exceptions. A registered person with a disability who withdrew because a physical or mental disability made continuing impossible, and a student managed outside the enrolment quota under the special education act, are not subject to the six-month rule.

Which is why the timing of withdrawal decides the sitting

The exam is held twice a year. The first sitting is usually in April and the second in August, with announcements roughly two months ahead of each.

A difference of a few days in the removal date therefore pushes eligibility back by four months. If the decision to withdraw has already been made, it is worth checking the announcement date of the next sitting before submitting the paperwork to the school.

If the six months have already passed, there is no reason to rush. The application window is usually about a week, so the only thing to avoid is missing it.

There are seven subjects

The compulsory subjects are Korean, mathematics, English, social studies, science and Korean history — six in total — plus one elective, making seven papers. The elective is chosen from ethics, technology and home economics, physical education, music and art.

The elective is declared on the application form, and candidates generally pick whichever is least demanding. What matters is that the chosen subject must actually be sat. The reason lies in the pass rule below.

The average is 60, but skipping one paper fails you

The pass mark is an average of 60 or above across all subjects. Each paper is out of 100, and the average is truncated at the third decimal place. A score of 40 in one subject is survivable if the others carry the average.

There is one exception. If any subject is not sat, the candidate fails regardless of the average. Skipping a weak subject and lifting the average with the rest does not work. Even if you cannot complete the paper, sitting it is the rule.

You do not have to finish in one go — subject passes

Any subject scored at 60 or above is recorded as a subject pass. If the candidate chooses, that paper is exempted from the next sitting and the earlier mark is carried into the final result.

This creates a workable strategy. With limited preparation time, you can secure 60 in the subjects you are confident about and concentrate on the rest at the following sitting. Splitting the exam across two sittings four months apart is common.

Claiming the exemption is your decision. If you would rather raise a mark, you may sit the subject again, in which case the new score applies.

How university admission works afterwards

Passing the exam confers status equivalent to high school graduation. Candidates may sit the national entrance exam, and regular admission is effectively unrestricted.

The difference shows up in early admission. With no school record to submit, record-based tracks are either closed or handled through a separate calculation. That method — converting equivalency exam marks into internal grade equivalents — is known as comparative grading, and both the formula and the tracks it applies to vary by university.

Eligibility must therefore be checked directly in the equivalency-exam applicant section of each university's admissions guide. General explanations will not match. The number of applications allowed is unchanged: the six early and three regular application limits apply in the same way.

Before you apply

Applications are filed with the office of education for your registered address. Windows, methods and required documents differ slightly between offices, so the announcement is the authority.

You will generally need the application form, a photograph, identification and proof of prior education. If you left high school partway, a document showing removal from the register is required, and the date on it is what the six-month rule is measured from. It can take time to issue, so request it before the window opens.

In order, then: confirm the removal date, compare it with the next announcement date, decide which sitting you are eligible for, and check the application window. Settling those four points is usually enough to avoid losing a sitting.

If the decision to leave has not been made yet, start by understanding how absences are recorded. What counts can change the options available, as set out in how attendance appears on the school record. Where attending at all is the difficulty, a conversation with the class teacher comes first — see what to ask at the parent-teacher meeting.
