What are skateboarding judges looking for in a run?

• Difficulty: "the most distinctive criterion". It covers how hard the trick is and the obstacle it is done on.
• Variety: a wider range of tricks of the same or higher difficulty makes a stronger impression.
• Execution and landing: style, speed, distance, energy and height, through the start, middle and end of each trick. "The quality of landing is a decisive part".
• Use of the course: moving through the course efficiently, using the key obstacles and keeping speed.
• Not a count: "a higher number of tricks does not necessarily result in a higher point evaluation".
• Consistency: landing tricks without falling. Not completing the full time of a run counts against it.
• Flow: connecting tricks in a way that is continuous, fluent and pleasing to watch.
• Stepping off: in street, stepping off the board between tricks may be judged a lack of flow.
• Repetition: repeating tricks or trick components, or using the same obstacle again and again, is "proportionally penalized".
• The decisive three: difficulty, variety and execution are named as "the decisive factors".
• Common sense: the criteria rest on the judges' own experience of skating and knowledge of its current state.

The glossary has the judging criteria, the overall impression, the difficulty entry, the variety entry, the execution entry, the use of the course, the flow entry and the repetition entry.

The criteria try to measure skateboarding without telling skaters what good skateboarding is. The document says so itself: it does not exist "to standardize or create a definition" but "to provide a framework for quantifying it". One overall mark lets a judge reward a run that is more than the sum of its tricks.
