How to Judge a Skateboarding Competition
The Complete Judge's Guide — Overall Impression, Criteria, Scoring Systems, and Best Practices
Last updated: March 17, 2026
Skateboarding judging is based on Overall Impression — judges evaluate each performance holistically rather than scoring individual tricks separately. A panel of 5 judges scores each run or trick on a 0–100 scale. Highest and lowest scores are dropped, remaining three are averaged. There is no official difficulty multiplier — a clean, stylish kickflip can outscore a sloppy 900. Judges assess difficulty, execution, variety, style, and use of course as interconnected criteria, not weighted categories. This guide covers everything you need to judge skateboarding competitions confidently at any level.
Understanding Overall Impression Scoring
Overall Impression: the core concept. You watch the skater. You absorb what happens. You assign one score. That's it. No difficulty table. No components added together. One holistic number representing what you saw.
This reflects how skateboarding actually works — it values innovation, style, and risk alongside difficulty. A skater landing something no one's landed before with clean execution and flow deserves the reward, even if the individual tricks aren't the hardest available.
What this means in practice:
Don't mentally add up trick scores. Watch the run. A strong run builds momentum — each trick adds to the overall arc. A fall reduces it, but one mistake doesn't erase everything else. Context matters: the same kickflip backside lipslide scores differently on a low rail versus a big handrail. Same trick, different context. A score of 85 at a local contest isn't the same as 85 at the Olympics. You're always comparing relative to the level and field. When you score, you're asking: how good was this performance overall?
The Five Judging Criteria
While Overall Impression is holistic, use five interconnected criteria as your mental framework. These are not separately weighted or scored — they inform the single overall score:
| Criteria | Description |
|---|---|
| Difficulty | Technical complexity of tricks performed. Includes flip tricks (kickflip, heelflip, tre flip), grinds (smith, feeble, crooked), combinations (flip-in/flip-out grinds), and stance variations (switch, nollie, fakie). Higher difficulty potential earns higher scores, but only if executed cleanly. |
| Execution | How cleanly tricks are landed and performed. Clean pop, proper catch in the air, stable landing, controlled roll-away. A wobble, foot drag, or hand touch on landing reduces execution quality. Even the most difficult trick loses impact if the landing is sketchy. |
| Variety | Diversity of trick types and obstacle usage. A run that includes flips, grinds, slides, manuals, and uses multiple obstacles scores higher than repeating the same trick type. Variety demonstrates well-rounded skateboarding ability. |
| Style & Flow | Personal expression, smooth transitions between tricks, speed maintenance, and confident body language. Style is what separates good skateboarding from great. Two skaters can do identical tricks — the one with more natural, effortless style scores higher. |
| Use of Course | Utilizing different obstacles and sections rather than sticking to one area. In street: using rails, stairs, ledges, gaps, manual pads. In park: using the full bowl including extensions, hips, deep end, shallow sections. Creative line selection through the course is valued. |
Scoring Runs: The 45-Second Performance
In both street and park, runs are timed performances (typically 45 seconds) where the skater links multiple tricks across the course. Judge the complete performance as a single unit.
What makes a high-scoring run:
Strong opening: A confident, clean trick sets the tone and establishes authority. Progressive difficulty: Building from solid tricks to harder ones throughout the run shows control and ambition. Smooth connections: Linking tricks without awkward pushes, stops, or hesitation demonstrates flow. Full course usage: Moving across different sections shows adaptability and awareness. Clean finish: Ending strong with a memorable final trick leaves a lasting impression.
How falls affect run scores:
A fall during a run significantly impacts the score, but judges must acknowledge the quality of everything before and after. A run with one fall but otherwise exceptional content might score 60–70, while a completely clean but uninspiring run might score 65–75. Context matters — the severity of the fall, how quickly the skater recovers, and how much quality content surrounds the mistake all factor in.
Run score benchmarks (approximate):
- 90–100: Exceptional — near-perfect execution of high-difficulty tricks with style and flow. Extremely rare.
- 80–89: Excellent — high difficulty, clean execution, strong variety and style. Occasional minor imperfections.
- 70–79: Very good — solid difficulty and execution with some notable strengths. Minor mistakes acceptable.
- 60–69: Good — competent skating with some standout moments but also noticeable weaknesses or a fall.
- 50–59: Average — basic tricks performed adequately, or harder tricks with significant execution issues.
- Below 50: Below average — multiple falls, limited trick selection, or incomplete run.
Scoring Best Trick Attempts
Best Trick is different — single trick, scored alone. The skater gets one chance per attempt to land one trick. You score that moment in isolation.
Key differences from run scoring:
Single trick focus: You're not watching a sequence. One trick. Difficulty, execution, style of that single trick. Higher risk tolerance: Skaters attempt way harder tricks in Best Trick because failed attempts don't count. A kickflip backside lipslide might be a 75 on a low rail but 90+ on the big handrail — same trick, different context. Progression rewarded: If a skater already scored 80, they'll try something harder on the next attempt. Landing the harder variation should score higher. You're scoring the progression, not punishing the challenge.
TNS (Trick Not Scored) mechanism: Paris 2024 introduced this. Athlete lands a trick but doesn't like the score? Crosses both arms above their head within 5 seconds of landing — that attempt is TNS (Trick Not Scored), counts as 0.0, no repetition penalty. They can immediately attempt the same trick again, harder. As a judge, treat TNS like a failed attempt (it's a 0), but understand the athlete is pursuing progression. This mechanism changed Best Trick from "don't mess up" to "push harder."
Olympic street format: 5 best trick attempts per skater. Only top 2 tricks add to the final score. 3 failed attempts or TNS refusals? Doesn't matter. This structure encourages skaters to go all-in on progression without fear.
JudgeMate's role: The system automatically identifies which 2 tricks count (the highest-scoring ones) and adds them to the best run score. You score each attempt independently. JudgeMate calculates what counts.
Street vs Park: How Judging Emphasis Shifts
Same 0–100 scale and five criteria apply to both disciplines, but the relative emphasis shifts.
Street Judging Emphasis
Technical precision is paramount. Street tricks on rails, stairs, and ledges demand exact pop height, proper lock-in position on grinds, and stable landings on flat ground. Trick selection on obstacles matters — choosing the right trick for the right obstacle demonstrates skate IQ. A smith grind on a kinked rail is more impressive than on a straight flat bar. Best trick importance is high — the best trick round in street allows for progression and strategy; judges should reward skaters who push boundaries. Line creativity in runs is valued — unique combinations of obstacles that flow naturally through the course.
Park Judging Emphasis
Flow and speed are essential. Park skating should look effortless — maintaining speed through transitions without unnecessary pushes. Amplitude (height above the coping) is a clear differentiator. Higher airs demonstrate power, control, and commitment. Transition usage matters — carving, pumping, and using the bowl's shape rather than just hitting the lip shows mastery. Aerial trick variety across different sections — 540s on one wall, a McTwist on another, combinations in the corner — demonstrates complete park skateboarding. Only the best run counts in park (3 runs, best score wins), so score each run independently as if it were the only performance.
The Trimmed Mean: How Individual Scores Become Final Scores
In professional skateboarding competitions, a panel of 5 judges scores each performance independently. Then the highest and lowest scores are dropped, and the remaining 3 scores are averaged. This is the trimmed mean.
Why the trimmed mean matters:
Prevents outlier bias: If one judge scores dramatically higher or lower than consensus, their score is removed. This protects against individual bias, national favoritism, or simple errors. Encourages honest scoring: Judges know that extreme scores will likely be dropped, encouraging them to score within a reasonable range of their peers. Maintains consistency: The middle three scores typically cluster within 3–5 points of each other at well-judged events, producing a result that reflects genuine consensus.
Example calculation: Judge scores for a run: 78, 82, 80, 75, 81
- Drop highest (82) and lowest (75)
- Average remaining: (78 + 80 + 81) / 3 = 79.67
JudgeMate performs this calculation automatically and in real time. Judges enter their individual scores, and the system instantly displays the trimmed mean to spectators and athletes on the live leaderboard.
Best Practices for Skateboarding Judges
Before competition:
Know the format. Street or park? How many runs, tricks, scoring scale (0–100 vs 0.0–10.0)? Walk the course. Understand which obstacles exist and what tricks they enable. Technical ledge combinations have different scoring implications than open transition. Attend the judges' meeting. Head judge establishes benchmarks. You align expectations with other judges. Calibrate together. Watch practice runs as a panel, discuss score ranges. This prevents the judges from being 20 points apart on the same skater.
During competition:
Score independently. Never look at other judges' scores before entering yours. That's the foundation. Use the full scale. Don't bunch everything 60–80. 90+ for exceptional. Below 50 for poor. Full range = meaningful separation. Stay consistent. Two equally impressive runs get similar scores. Consistency matters more than hitting a specific number. Falls scale proportionally. One fall in an otherwise strong run: meaningful deduction, not catastrophic. Multiple falls: larger impact. Don't chase consensus. You believe it's an 85, the average is 78? Score 85. The trimmed mean handles disagreements.
Common mistakes:
Tricks you don't recognize: Assess execution, not the name. Clean pop? Stable landing? Controlled? You don't need to know it's a "kickflip backside lipslide" to score it. Overweighting difficulty: Sloppy 900 does not beat perfectly executed 540. Execution and style matter equally. Recency bias: Don't let the last skater influence this one's score. Judge each on its own merits.
Worked Example: Judging a Street Competition Run
Walk through the thought process of scoring a 45-second street competition run.
The run: The skater pushes off and approaches the 8-stair set. Pops a clean kickflip down the stairs — good height, caught well, stable landing. Rolls to the flat bar and locks into a frontside boardslide, sliding the full length before popping off cleanly. Transitions to the hubba ledge, does a backside smith grind — technical, locked in, clean exit. Pushes to the manual pad and holds a long manual (10+ feet) before kickflipping out. Moves to the big rail, attempts a backside 50-50 but steps off at the end — a minor bobble but stays on the board. Finishes with a frontside 180 over the gap.
Judge's mental assessment:
Difficulty: Medium-high. Kickflip down 8 stairs, smith grind, long manual with kickflip out — solid technical content. No cutting-edge tricks but consistently challenging.
Execution: Very clean except for the 50-50 step-off. Five of six tricks landed perfectly. The manual was impressive in length and control.
Variety: Good — flip tricks, grinds, manuals, gap trick. Used multiple obstacle types.
Style: Smooth transitions, good speed throughout, natural body positioning. The kickflip catch was particularly clean.
Use of course: Good — used stairs, flat bar, hubba, manual pad, rail, and gap. Covered most of the course.
Overall impression: Strong run with one minor mistake. The consistency and flow were impressive, the trick selection was smart, and execution was mostly clean. The step-off prevents it from being elite, but it's clearly a high-quality performance.
Score: 78
Rationale: Above the "very good" threshold (70+) due to overall quality and variety. Below the "excellent" range (80+) because the step-off on the big rail — which could have been a highlight moment — reduced the overall impression. If the 50-50 had been clean, this run could have been an 82–84.
