Mixed martial arts bouts that do not end in a knockout, technical knockout, or submission are decided by the scorecards of three ringside judges. The sport uses the 10-Point Must System, which was adopted from professional boxing. However, the criteria used to evaluate rounds differ significantly from boxing, accommodating the ground combat and diverse striking mechanics of MMA.
The 10-Point Must Mechanics
Under the 10-Point Must System, judges must award exactly 10 points to the winner of the round. The loser of the round receives 9 points or fewer. Points can also be deducted by the referee for rules infractions (fouls), which are subtracted from the final round tally.
Typical round scoring outcomes include:
- 10-9 Round: A close round where one fighter won by a narrow but clear margin. This is the most common score in MMA.
- 10-8 Round: A round where one fighter dominated the competition through damage, positional dominance, or duration of control. Under current guidelines, judges are heavily encouraged to award 10-8 scores for highly one-sided rounds.
- 10-7 Round: An extremely rare score awarded only when a fighter is completely dominated, suffers severe damage, and is nearly stopped multiple times.
- 10-10 Round: A round that is completely even. Judges are strongly discouraged from scoring a round 10-10 unless there is absolutely no difference to evaluate.
The Hierarchy of Judging Criteria
According to the Unified Rules of Mixed Martial Arts, judges must evaluate rounds based on a strict hierarchy of criteria. Judges do not look at the round as a whole without structure; they must evaluate criteria in sequence.
- Effective Striking / Effective Grappling: This is the primary tier of evaluation. If one fighter has a clear advantage here, the round is scored for them. No other criteria are considered.
- Effective Aggressiveness: This is evaluated only if the striking and grappling of both fighters are deemed exactly equal.
- Fighting Area Control (Octagon Control): This is the final tie-breaker, evaluated only if both striking/grappling and aggressiveness are completely equal.
Tier 1: Effective Striking & Grappling
This is the primary scoring criteria. Effective Striking is evaluated by the total number of legal strikes landed by a competitor, with a focus on impact. Impact is measured by immediate damage (e.g. staggering an opponent, swelling, cuts) and cumulative wear. Quantity of strikes is secondary to the quality and damage caused.
Effective Grappling is evaluated by the execution of legal takedowns, submission attempts, transitions to dominant positions, and active ground control that has the potential to end the fight. Crucially, simply holding an opponent on the ground without attempting to score damage or find a submission is not considered effective grappling.
Tier 2: Effective Aggressiveness
If striking and grappling are completely even, judges look at aggressiveness. This means actively forcing the action, moving forward, and attempting to finish the fight. Mindless forward movement without landing strikes or grappling control does not count; the aggressiveness must be effective.
Tier 3: Fighting Area Control (Octagon Control)
As a final resort, judges look at who dictated the pace, place, and position of the bout. A fighter who keeps their opponent against the fence or controls the center of the cage may win this tie-breaker if all other metrics are dead-even.
"The modern judging criteria emphasize damage and impact over control. Holding an opponent against the cage or on the ground without landing strikes or attempting submissions is no longer sufficient to win a round if the other fighter landed more impactful strikes."
Understanding Decision Types
At the end of the bout, the judges' scorecards are tabulated. The final result is announced based on the judges' consensus:
| Decision Type | Judge 1 Scorecard | Judge 2 Scorecard | Judge 3 Scorecard |
|---|---|---|---|
| Unanimous Decision | Fighter A Wins | Fighter A Wins | Fighter A Wins |
| Split Decision | Fighter A Wins | Fighter B Wins | Fighter A Wins |
| Majority Decision | Fighter A Wins | Fighter A Wins | Draw / Even |
| Unanimous Draw | Draw / Even | Draw / Even | Draw / Even |
| Split Draw | Fighter A Wins | Fighter B Wins | Draw / Even |
| Majority Draw | Draw / Even | Draw / Even | Fighter A Wins |
Frequently Asked Questions
Under the Unified Rules, judges are instructed to score a round 10-8 when a fighter wins the round by a large margin. Judges look for three main factors: damage/impact (causing significant wear or staggering), dominance (total control on the feet or ground), and duration (maintaining dominance for the majority of the round). If all three are present, a 10-8 is mandatory. If two are present, a 10-8 is heavily considered.
No. A takedown is a transition tool. Under current criteria, a takedown only scores if the fighter uses it to launch submission attempts, advance position, or land impactful ground strikes. If Fighter A gets a takedown but Fighter B immediately stands up or attacks with submissions from the bottom, the takedown holds very little weight on the scorecards.
Yes. A single round can be scored 10-10 if it is completely equal. However, draws are more commonly the result of point deductions (e.g. a fighter wins two rounds 10-9 but has 1 point deducted for a foul, resulting in a 28-28 final scorecard tally).
