🏅 NASKA Scoring

5 judges: highest and lowest scores are dropped; middle three are summed. Scores must be within 0.02 of the middle score — if not, the outlier is adjusted.

Scoring Formulas

WKF (2019+, per wkf.net):

Sort each of the 7 T scores and 7 A scores individually. Drop the 2 highest and 2 lowest from each set → 3 scores remain each. Total = (T₁ + T₂ + T₃) × 0.70 + (A₁ + A₂ + A₃) × 0.30 Max = (10 + 10 + 10) × 0.70 + (10 + 10 + 10) × 0.30 = 30.0

NASKA (per naska.com):

5 judges: drop highest and lowest → sum middle 3. Scores within ±0.02 of middle. 3 judges: sum all 3 scores. Elimination range: 9.90–9.99 | Finals range: 9.96–10.00

Traditional / Local:

Drop High+Low → sum remaining OR Sum all OR Average all Score range set by individual tournament or governing body.

Frequently Asked Questions

How does WKF kata scoring work?
Seven judges each give a Technical score (T) and an Athletic score (A) on a 5.0–10.0 scale in increments of 0.2. The two highest and two lowest scores are dropped from each category independently, leaving three scores per category. The final total is: (sum of 3 kept T scores × 0.70) + (sum of 3 kept A scores × 0.30). The maximum possible total is 30.0 (three 10.0 technical scores + three 10.0 athletic scores). This system was introduced by the WKF in 2019, replacing the previous flag system, and was used at the 2020 Tokyo Olympics.
What is the maximum kata score in WKF?
The maximum WKF kata score is 30.0. This would require three kept Technical judges to each score 10.0 (contributing 21.0 at 70% weight) and three kept Athletic judges to each score 10.0 (contributing 9.0 at 30% weight): 21.0 + 9.0 = 30.0. In practice, elite competitors at Karate1 Premier League events typically score in the 24–27 range.
How does NASKA kata scoring differ from WKF?
NASKA (North American Sport Karate Association) uses 3 or 5 judges scoring on a narrow high-precision range: 9.90–9.99 in eliminations and 9.96–10.00 in finals. With 5 judges, the highest and lowest are dropped and the middle three are summed (max 29.97 in eliminations, 30.00 in finals). With 3 judges, all three are summed (max 29.97 / 30.00). Critically, NASKA rules require no two scores to differ by more than 0.02 from the middle score — any outlier must be adjusted. WKF uses a much wider 5.0–10.0 range with separate technical and athletic categories and a 70/30 weighting.
How are WKF kata tiebreakers resolved?
WKF tiebreakers are applied in this order: (1) the highest total of the three kept Technical scores before the 70% weighting is applied; (2) the highest single kept Technical score; (3) the highest single kept Athletic score. If all three criteria are still equal, additional procedures in the WKF competition rules document apply. This calculator displays all three tiebreaker values automatically so judges have them ready.
What score range do WKF kata judges use?
WKF judges score from 5.0 to 10.0 in increments of 0.2 for both Technical and Athletic categories. A score of 0.0 is given only for disqualification. In practice at elite international events, scores rarely fall below 7.0. Regional and national tournaments affiliated with WKF use the same 5.0–10.0 range, though some local clubs use a 0–10 range without the 0.2 increment restriction.
Can I use this calculator for team kata?
Yes. Team kata (performed by three athletes simultaneously) follows the exact same WKF scoring formula. The seven-judge panel scores the team as a single unit using the same T and A categories, and the same trimmed 70/30 calculation applies. Simply enter the 7 Technical and 7 Athletic scores that the judges awarded to the team's performance.
What is the difference between kata and kumite scoring?
Kata scoring evaluates a solo (or team) performance of pre-defined forms: judges assess Technical execution (stances, technique, rhythm, timing — 70%) and Athletic performance (speed, power, balance — 30%) on a numerical scale. Kumite (sparring) is point-based: Yuko (1 pt), Waza-ari (2 pts), and Ippon (3 pts) are awarded for correctly executed controlled strikes to legal target areas. A kumite match is won by reaching an 8-point lead or having the highest score at time. There are no trimmed averages in kumite — every awarded point counts.
Why are the two highest and lowest scores dropped?
Dropping the extreme scores is a form of trimmed mean that reduces the impact of any single judge who scores significantly higher or lower than consensus — whether from bias, distraction, or genuine disagreement. It smooths out outlier opinions while still using input from all seven judges. The same approach is used in Olympic figure skating and diving scoring.
