sharp blast on the whistle. The Chief judge must ensure that all Judges are ready before he

calls for score to be displayed in unison.

– The caller/announcer will announce the scores awarded beginning with the referee and then

continuing in a clockwise manner. When these scores have been registered, the referee will

blow a further sharp blast on the whistle, whereupon the cards will be lowered. (The referee

may also blow a further blast on the whistle to allow the judges to turn their scorecards for

better viewing for the spectators, prior to lowering their scores.)

– When the scorekeeper summates the scores for each competitor in the round, the maximum

and minimum score is permanently excluded from the total for that round.

Technique with “good form” is said to have characteristics conferring probable effectiveness

within the framework of traditional Karate concepts.

  1. Correct attitude – is a component of good form and refers to a non-malicious attitude of

great concentration obvious during delivery of the scoring technique.

  1. Vigorous application – defines the power and speed of the technique and the palpable will

for it to succeed.

  1. Zanshin – is that criterion most often missed when a score is assessed. It is the state of

continued commitment, which endures after the technique has landed, and the ability to

continue with proper form, other continuing techniques. The competitor with Zanshin

maintains total concentration and awareness of the opponent’s potentiality to counter


  1. Proper timing – means delivering a technique when it will have the greatest potential


  1. Proper distancing – means delivering a technique at the precise distance where it will

have the greatest potential effect. Thus if the technique is delivered on an opponent who is

rapidly moving away the potential effect of that blow is reduced.

– A Full Point may also be awarded for techniques deficient in one of the above criteria but

  which conform to the following schedule:

– Jodan Kicks or other technically difficult techniques.

– Deflecting an attack and scoring to the unguarded target of the opponent.

considered valid.

scored and may result in a penalty being imposed on the offender.

– Technique, even if technically correct, will not be scored if it is delivered when the two

competitors are outside the competition area. However, if one of the opponents delivers an

effective technique while still inside the competition area and before the Referee calls “YAME”,

the technique will be scored.

– Technique can be scored if delivered after a penalty that will be issued to the opponent.
