This coming weekend the USTC (United States Taekwondo Committee) is hosting officials from the Kukkiwon, located in Seoul, Korea, to present a special Referee seminar. This seminar is focused on the Kukkiwon forms. The Kukkiwon forms (poomsae) are a standardized set of techniques put together in a pattern for training. Training in those patterns will teach many things related to self-defense. Unfortunately, many of the instructors in America have created their own version of the Kukkiwon standards. Competing in the Hanmadang World Games or the WTF International Championships requires you to know absolutely the exact method of performing the poomsae as done by the originators, the South Koreans at the Kukkiwon.
Those in attendance will be either getting certified as a Hanmadang IR, being re-certified as a Hanmadang IR (that's me..) or if you're a 3rd DAN or lower getting certified as a US Hanmadang official.
Being certified as a Hanmadang IR means that you underwent the training necessary to grade and judge the performance of those competing. To know when and where they made mistakes and the appropriate amount of points to deduct. It's harder than it sounds because of all the factors you have to watch for.
