By fall semester of 9th grade, the conversation usually centers on high school applications and assignment, but what actually shapes the years after enrollment is which courses a given school offers. Under the high school credit system, even general high schools differ in how many courses -- and which ones -- they actually run. Here's how to check before assignment, or before applying if your school is one you can apply to.

Under the credit system, "general high school" doesn't mean the same thing everywhere

The high school credit system lets students choose courses that match their intended path. The catch is that how many courses a school can offer depends on its teacher headcount, facilities, and student demand -- and that varies school to school. Among general high schools alone, some offer more than 20 career-elective courses while others offer far fewer. If you only find out after assignment that "this school doesn't have that course," your options narrow considerably, so it pays to check ahead of time. Smaller or newly opened schools in particular often haven't fully staffed up yet, so they tend to offer fewer courses -- worth weighing school size alongside course count.

How to check the curriculum table on School Info

School Info (schoolinfo.go.kr), run by the Ministry of Education and the Korea Education and Research Information Service, publishes disclosure data for every school nationwide. Search by province, district, and school name, open the school's detail page, and under "Matters Concerning School Curriculum Organization, Operation, and Evaluation" you can see the hours and credit allocation broken down by grade and subject. As a first step, look up a few schools you're considering and compare whether the career-elective courses you're interested in are actually offered. The disclosure also lists how many semesters each course runs, not just whether it exists -- so you can check duration as well as availability.

If you're headed toward a STEM track, check especially closely

If you're considering a science-track major, this matters even more. Seoul National University, for instance, recommends that applicants to its natural-science track complete "Geometry" and "Calculus II" during high school -- courses that schools sometimes don't offer at all if demand is low. If your intended path requires specific courses, searching School Info by the exact course name is far more reliable than going on hearsay about which school is "supposed to be good." If your path all but presupposes certain coursework -- medicine or engineering, for example -- it saves wasted effort to first check the recommended or recognized subjects in your target university's admissions guide, then narrow your school candidates by that course list.

If a course isn't offered, shared-curriculum programs are an alternative

If your school doesn't offer a course, that doesn't mean it's completely out of reach. Provincial and metropolitan education offices run shared curriculum programs (on-site hub schools and online programs), letting students take courses not offered at their own school through a nearby hub school or an online class. On-site programs typically run after school or on Saturdays at a nearby school, while online programs run over video and involve no commute. That said, courses completed through a shared curriculum program are often recorded on the transcript as completed without a rank-based grade, marked with a dot rather than a letter grade -- so decide in advance whether you need a graded course or whether completion alone is enough. Since application timing and available slots vary by school and education office, the fastest practical step after enrolling is to ask your homeroom teacher or career counselor when shared-curriculum applications open.

How much course variety a school offers differs by high school type

General, autonomous private, special-purpose, and vocational high schools are designed around different curricular approaches to begin with, so how wide a range of courses each can offer differs too. A general high school designated as a science-focus school tends to run more advanced science courses, while foreign language and international high schools weight toward specialized language courses. If you already have a clear path in mind, the right order is to weigh "school type" against the "actual course list" together. That said, assignment systems vary by region (school zones and districts), so you won't necessarily get into the school you want -- checking ahead still helps you make sense of the assignment result and plan how to cover any missing courses afterward. If you live somewhere that limits which schools you can even apply to, just narrow your comparison to the schools within that range.

What to check now (fall semester) versus later

Right now, in the fall of 9th grade, it's enough to skim the most recent School Info disclosures for the schools you're considering. Since the data is updated every school year, it won't be the exact curriculum for the year you actually enroll, but it's more than enough to get a sense of which subject areas a school tends to emphasize. Comparing two or three schools the same way will start to show you their relative leanings toward particular tracks. Confirm the finalized curriculum again through the pre-enrollment orientation or early-semester notices once you actually enroll -- and keep in mind that some courses may be dropped or added in the meantime, so don't treat what you see now as final.

Worth checking alongside this

If you haven't settled on a high school type yet, it helps to first sort out what actually differs between general, autonomous private, special-purpose, and vocational high schools. To understand why some courses show up on the transcript without a rank-based grade after enrollment, see how the credit system and course choice reshape the transcript. If you're weighing a STEM path, it's also worth checking the subjects Seoul National University recommends for its science track.

Steps in order

①Pick a few candidate schools you're considering. ②Look each one up on School Info (schoolinfo.go.kr) and check "Matters Concerning School Curriculum Organization, Operation, and Evaluation." ③Compare whether the specific courses your intended path requires are actually offered. ④If not, check whether a shared curriculum program (on-site or online) can cover it, and whether you need a graded course or completion is enough. ⑤Once assignment results are out, confirm the finalized curriculum again through pre-enrollment orientation or early-semester notices.
