World Skate International Skateboarding Judging Commission Workshop


Amongst the many responsibilities of World Skateboarding as Tokyo 2020 approaches, one of the most important is standardizing the process and criteria of how skateboarding contests are judged.

Quality and consistent judging are the basis of fair competition and ensure that skaters around the world know what’s expected of them as they begin the qualification process for the Olympic Games. Poor judging, on the other hand, does the opposite—and worse—as it can actually cripple the progression of a sport.

Amidst four days of deliberation, 17 skateboarders from 11 different countries, with over 500 years of combined skateboarding experience, worked diligently to translate the inherent recognition of what makes good skateboarding from something "you know when you see it," to something that can be written down and explained to skateboarders all over the world. Again and again, the value and appreciation of progression, creativity, and originality rose to the forefront as we labored to ensure that the criteria we produced supported the continual positive growth of skateboarding on all levels.

At the premiere of "Tony Alva’s Loveletters" documentary, Tony summed up our thinking when he shared his philosophy and approach to skateboarding as “progression over perfection.”

Three simple words that perfectly describe what makes for great skateboarding, spoken with zen-like simplicity, by someone who has spent more time on a skateboard than almost anyone on the planet.

Here’s a more in-depth explanation:


The International Skateboarding Judging Commission (ISJC) Skateboarding Judging Criteria was created to foster the continual progression of skateboarding while highlighting the importance of creativity and originality of skateboarding in competition.


  • Skateboarding judging doesn’t exist to standardize or define what is considered good skateboarding, it is strictly a tool to rank the performance of skateboarders against each other in a given competition.
  • Scoring is based on judging the current performance or moment in time.
  • Judging is based on a skater’s performance against the current field, not against their past performances or ability.


  • The judging panel will use the below criteria to formulate a single score based on the overall impression of a skater’s performance within the parameters of the competition.

JUDGING CRITERIA (in order of priority)

  • Difficulty
    • Trick Performed
    • Obstacle Selection
  • Execution
    • Quality of Execution
    • Style
      • Fluidity / Power / Aggression / Aesthetics
      • Speed
      • Height / Distance
      • Quality of Landing
    • Use of Course
      • Variety of Tricks
        • A higher number of tricks will not necessarily result in a higher score as the value of difficulty and execution are more important in formulating an overall impression score.
      • Variety of Obstacles
      • Flow (for runs only)
  • Consistency (for runs only)
    • While consistency and runs without any bails are a key factor in any high-scoring skateboarding performance, consistency alone will not be enough to win a competition, as the value of difficulty, execution, and use of course are more important in formulating an overall impression score.
