01 Levels & digital badges
CKL has three levels. Grade 1 is the highest (the reverse of TOPIK). Each level earns a verifiable digital badge.



02 Exam subjects
Subjects differ by grade. CKL assesses four skills — two receptive (Listening, Reading) and two productive (Writing, Speaking). Grade 3 covers two skills, Grade 2 covers three, and Grade 1 is the only grade assessed on all four. Each subject is out of 100.

Use-it-or-lose-it: a free voucher is valid for 6 months from issue — study and take your exam within that window. Partial re-sit: you re-sit only the subject you failed, at about 60% of the full fee — $33 for Grade 2, $44 for Grade 1. Note: Grade 1 Speaking & expression is held once a month, so re-sitting it can mean waiting up to about one month for the next session. Every other subject can be re-sat on demand.
05 Passing, certificate & renewal
- Passing criteria: Each subject is out of 100. You must score at least 40 in every subject (below 40 fails that subject) and average 60+ overall.
- Digital certificate: Issued online at no extra cost — with your gold/silver/bronze badge and a verifiable record (WIA Chain).
- Physical certificate: From 2026, physical cards/diplomas are discontinued as part of our environmental policy — certificates are digital.
- Renewal: Valid for 2 years from the pass date; renew by completing 30 continuing-education credits.
06 How the exam runs

- AI proctoring: Identity and integrity are verified during the exam (camera + activity checks).
- Results: Multiple choice is auto-scored on submit. Writing is scored against a rubric — most results are confirmed automatically, and any sent for human review are returned within 3 business days. Speaking is assessed by human assessors and returned within 3 business days. Business days follow the Korean calendar (public holidays excluded).
