Judging Certification Program
The scorekeeper to international judge certification ladder.
Background
The Judging Certification Program traces back to 2002, when the Rules and Judges Training Committee — an ad hoc committee of the Technical Advisory Committee — built the original certification system, mentoring structure, and training materials. In 2009, Grandmaster Shin formed the Judging Certification Committee to keep reviewing and updating the process.
The four levels
| Level | Eligibility | Requirement to certify |
|---|---|---|
| Scorekeeper | Cho Dan Bo at least 14 years old, or 5th gup and higher at least 16 years old | Pass the written test |
| Corner Judge | Dan member at least 16 years old | Certified scorekeeper with documented experience at 1+ championship (log sheet required); pass written and practical tests |
| Regional Center | Certified corner judge | Documented experience at 2-3 championships as corner judge (log sheet required); pass written and practical tests |
| International | E Dan and higher | Certified regional center with documented experience; must have judged a World Championship; pass written and practical tests |
Cho Dan Bo members 16 and older can be certified as corner judges, but they aren't permitted to actually judge until they become Dan members.

Tracking your experience
Serving as a judge, scorekeeper, timekeeper, or arbitrator all count as judging experience. The head table — or whoever is responsible for ring assignments at that championship — signs your log sheet.
Renewal and upgrades
- Certification is valid for 5 years. Once it expires, the judge starts the certification process again.
- Re-certifying as a Center or International judge requires a completed log sheet documenting experience.
- If a judge can't verify the required experience and other requirements for Center judge, the process restarts from Scorekeeper.
- Sah Dan and above are not required to keep a log sheet.
- Upgrading to the next level still requires completing the testing process and paying the fee, even if the experience requirement is already met.
