Korea's High School Credit System: The First Year of Full Implementation

In March 2025, South Korean high school classrooms quietly transformed. Incoming first-year students began a school life where they needed to choose their own courses within a common framework of core subjects. South Korea's high school credit system (고교학점제) — debated for nearly a decade and delayed multiple times — finally entered full nationwide implementation. As the first year draws to a close, it's time to assess whether the system is working as intended.

What Is the High School Credit System?

Korea's high school credit system works like a university model: students select the courses they want, earn credits upon adequate achievement, and graduate once they've accumulated 192 credits. The idea is to move away from teacher-led, textbook-centered instruction and give students the ability to design their own learning path based on their interests and career goals.

This is not simply about broadening course options. It requires a structural transformation of how teachers teach, how schools use space, and how timetables are built.

What Changed in 2026

In January 2026, the Ministry of Education announced support measures for the system and made several important adjustments.

Credit acquisition standards were relaxed. Previously, students needed to meet both an attendance rate and an academic achievement threshold. Starting this year, attendance alone is sufficient to earn credits for elective courses — a move to reduce pressure on schools.

School record character limits were also shortened. Homeroom teachers' behavioral characteristic entries were reduced from 500 to 300 characters, and extracurricular activity records from 700 to 500 characters, easing the administrative burden on teachers.

The Ministry allocated 15.7 billion won to support diverse elective course offerings at rural and small schools, and made it possible for students to earn credits through an online platform when on-site options are unavailable.

The Gap Between Policy and Classroom Reality

There is always a temperature difference between policy design and actual classroom experience. A 2025 study published in Cogent Education (Tandfonline) on secondary teachers' perceptions found that more experienced teachers tended to show greater skepticism toward the system. The reasons are layered:

  • Pressure to teach outside their area of expertise
  • Increased administrative work from timetable restructuring
  • Doubts about whether students are truly ready to make meaningful course choices

The inequality concern is especially prominent in rural and small-town schools. Where teacher numbers are limited and physical space is scarce, the range of elective courses on offer is simply narrower from the start. If urban students at large schools enjoy genuine course selection freedom while rural students don't, this system risks reinforcing educational inequality rather than reducing it.

Are Students Actually Ready to Choose?

The most fundamental question the credit system poses is this: can high school students design a course path aligned with their interests and goals?

In practice, many students still evaluate choices primarily through the lens of college admissions. "Will this subject help on the national college entrance exam?" and "How will this be scored in university applications?" remain the dominant criteria. As long as that calculus drives selection, the system's intent will only be half-realized.

True self-directed learning requires awareness of one's direction, exploratory experiences, and a strong counseling infrastructure. Changing the institutional structure alone does not automatically build students' capacity to choose well.

What to Watch Going Forward

The high school credit system is a reform where successful implementation matters more than the launch itself. The questions worth monitoring include:

  • Is the gap in elective course availability between schools widening or narrowing?
  • How will the tension between absolute grading standards and competitive university admissions be resolved?
  • Is there adequate professional development support for teachers adapting to new roles?

The Ministry has stated it will continuously collect field feedback through monitoring groups and advisory committees. How transparently and quickly that process unfolds will determine whether this reform succeeds.

The direction of the high school credit system is right. But a sound direction does not mean the field is prepared.
