7.3 Scoring

The starting scoring must be reduced for every mistake.

7.4 Mistakes

  • Technical mistakes
  • The demonstration of the technic does not meet the prescribed requierements
  • Incorrect stances/positions: the relation of extremities, trunk, head to each other does not correspond to that prescribed or to the optimal.
  • Mistakes of the style: countenance, direction of sight, understanding of the kata


The competitor must be disquified in the following cases:

  • alters the kata.
  • presents a kata different from the previously announced.
  • makes change in the sequence or direction of technics.
  • falls down.
  • stops the presentation.


The deduction must be done according to the severity of the mistakes, devided into the following three categories:

9.1 Small mistakes (0.1)

A demonstration close to the perfect, a litle alteration can be observed from the correct execution.


a) technical:

  • the position of the arms is correct, the fits are not close properly.
  • there is some variation in performing the same technic: the chudan level is not always the same etc.

b) stances and positions:

the stances and positions are correct according to the prescriptions, but:

  • the same stance is presented in different sizes, the difference is less than 10 degrees or 1 foot in length.
  • the altitude of the similar stances differs, the difference is less than one palm.
  • the kata is completed in a point different from that prescribed, but closer than l foot to it.

c) style:

his countenance overacts the demonstration: overemphasizes the fighting feature of the kata.

9.2 Moderate mistake (-0,2, 0,3)

Significant deviation from the perfect demonstration.If the mistake is closer to the “litle” categorie, 0,2, if to the “rough” category, 0.3 points are to be lost.


a) technical:

  • incorrect start and end –position of the arm or leg: inproper hikite-too low.
  • punches, blocks, strikes starting from a position in front from that requiered.
  • overstretched arms ending a punch.
  • in the case of a punch or strike the trunk is not perpendicular to the direction of the technic but the angle does not exceed 45 degrees.
  • vice versa: in the case of a block the trunk does not turn to the requiered position ( 45 degrees).
  • visibly loose fist in hikite.
  • inproper speed of the technic (too slow or to fast).
  • in the case of a kick the heel of the supporting leg is lifted.

b) stances and positions:

  • visible fault in the in the executionof a stance: the difference is more than that allowed.
  • visible difference of the level of similar stances (Zenkutsu-dachi, Kiba-dachi, Kokutsu-dachi) what results in the waving of the kata.
  • the kata is completed in a place different from that prescibed, the difference exceed 1 foot.

c) style:

  • directing of the sight does not preceed the technic.
  • the tempo of the kata is not correct: too slow or too fast.
  • the stretched and relaxed phase of the technic is not evident.

9.3 Rough mistake (- 0,5)

Major divergence from the correct presentation.


a) technical:

  • altered level of a technic: jodan kick instead of chudan.
  • keage- like kick instead of the prescribed (e.g. yoko-geri)
  • absence of kiai.
  • overturning of the body in the end position (more than 45 degrees in the case of punch ior strike)
  • absolute absence of the turn in the case of a block.

b) stances and positions:

  • too high stances.
  • large range in the length and altitude of the same stance.


10.1 Results in a round

  • In the case of a draw, the lowest score accorded must be also involved in the calculation. If there is further a draw, th highest score is also calculated (the points accorded by the main judge and judges, devided with 3, to the third place of decimals).
  • If there is still a draw, a new kata must be presented: a compulsory kata in the 1st round, a free kata in the Final.

10.2 Calculating the Final Result and Placing

  • The valid scores of the rounds must be summarized.
  • The competitor who gained a higher score must obtain a higher place.
  • In the case of a draw the score gained in the first round makes the decision.
  • If there is still a draw, the competitors must present a new free kata (not done in the previous rounds).
