The Nationwide Joint Achievement Test has, until now, been open only to students enrolled in school. If your child withdrew from school, you likely assumed they simply weren't eligible. But starting with the 12th-grade achievement test on October 20, out-of-school youth in Seoul will sit in an exam room for the first time. It's a change that arrived five months after a court ruling -- and something more urgent is due even sooner. The deadline to apply for mock-exam fee support for out-of-school youth preparing for the CSAT closes on September 30.

The achievement test was built for enrolled students only

The Nationwide Joint Achievement Test is administered by regional education offices under the Elementary and Secondary Education Act to diagnose enrolled students' academic progress. Grades 10, 11, and 12 each sit it several times a year on separate schedules, but on Tuesday, October 20, 2026, all three grades will test on the same day. Graduates, including retaking students (n-suseng), were never eligible to begin with -- the test's entire purpose was to diagnose the curriculum for enrolled students. Out-of-school youth fell under that same enrolled-student bar, so their applications were never even accepted.

In March 2026, a court challenged that bar

Two teenagers who had withdrawn from middle or high school applied to sit the test in March 2025 and were turned down on the grounds that it was for enrolled high school students. They sued to have the rejection overturned, and the Seoul Administrative Court's 5th Administrative Division (Chief Judge Lee Jeong-won) ruled in the plaintiffs' favor on March 26, 2026. The court found that the disadvantage the plaintiffs suffer from the rejection outweighs the public interest served by it, and that the need for out-of-school youth to receive academic achievement data is recognized as equal to that of enrolled students. At its core, the ruling affirms a principle: dividing educational opportunity by enrollment status alone requires a public-interest justification substantial enough to support it.

Five months later, Seoul's education office announced a pilot

After reviewing the ruling, the Seoul Metropolitan Office of Education announced in August 2026 that it would run a pilot allowing out-of-school youth to sit the October 12th-grade achievement test. The exam is held at test centers designated by the office, and there is no fee. Two details are easy to miss here: a court ruling doesn't change policy overnight, and this is, for now, a Seoul-only pilot. If your child withdrew from school recently, it also helps to know that you cannot sit the high school equivalency exam right after withdrawing -- you must wait six months from official withdrawal, so you don't confuse that timeline with this application's eligibility rules.

Eligibility -- not everyone qualifies

This pilot is open to out-of-school youth as defined under the Act on the Support for Out-of-School Youth who are planning to take the 2027 CSAT. On top of that, applicants must be registered with one of three organizations -- the Seoul Out-of-School Youth Support Center, Seoul Kkumdream Center, or the Seoul education office's out-of-school youth help center -- and must have either passed the high school equivalency exam or be registered for the 2026 second-round equivalency exam. Withdrawing from school alone doesn't make you eligible; you first need to complete both center registration and the equivalency-exam process. Applications were accepted online through the three centers from August 3 to 11, and this round has already closed. If your family missed this window, registering with a support center now is the practical move for the next round.

A more urgent deadline is still open -- mock-exam fee support closes September 30

Separately from the achievement test, the Ministry of Gender Equality and Family covers mock-exam fees for out-of-school youth aged 9 to 24 sitting the CSAT mock exams run by the Korea Institute for Curriculum and Evaluation for the 2027 CSAT cohort. You can be reimbursed 12,000 won per sitting, up to 24,000 won per person, and both the June and September mock exams qualify. The application window runs from June 4 to September 30, 2026, and you apply through the service-request menu on Youth1388 (1388.go.kr) or via the QR code on the program's flyer. Even if you already paid the fee out of pocket, applying before September 30 gets it reimbursed retroactively -- so keep your payment or registration confirmation on hand.

What the score is actually used for -- still unsettled

The Seoul education office frames the pilot's purpose as boosting motivation to learn and providing objective data for career and university planning. Whether this score will be weighted the same way as an enrolled student's in regular early-decision and regular-round admissions, or whether it will remain purely a reference document, hasn't been made clear yet. Reading the full 12th-grade calendar of achievement tests, mock exams, applications, and the CSAT shows where this test sits in the overall sequence, but whether it carries the same weight as an enrolled student's result is something that will only become clear once the pilot has run its course.

Nationwide expansion next year is still just under discussion

The Seoul education office says that, based on how this pilot goes, it plans to discuss expansion with all 16 regional education offices starting next year. No confirmed timeline exists yet, so out-of-school youth outside Seoul cannot sit this October's achievement test. That said, many crisis-youth support programs operate regardless of region, so it's worth checking whether programs like the Crisis Youth Special Support Program, which covers living, medical, and study costs, apply to your family. If your child is considering withdrawing from school, start with the mandatory deliberation period before filing a withdrawal form, then plan the equivalency exam and achievement-test steps in order to keep things less chaotic.

What to check right now

1. If you already paid for the September mock exam, apply for fee support on Youth1388 before September 30.
2. If your out-of-school teen lives in Seoul, check registration status with an out-of-school youth support center, Seoul Kkumdream, or the education office's help center.
3. Confirm equivalency-exam pass status or 2026 second-round registration, and note the timing for the next achievement-test application window.
4. If you're outside Seoul, this October's test isn't an option yet, but check eligibility for other support programs such as the Crisis Youth Special Support Program.
