MMA Judging Explained: The Criteria, the 10-8 Round and the Myths

MMA judging gets blamed for a lot. Some of it is fair. A lot of it comes from fans scoring a different sport from the one the judges are scoring. The Unified Rules of MMA lay out exactly what judges should reward and in what order. Once you know that order, most "robberies" look a lot less mysterious, and the genuinely bad cards stand out even more. Here is how a round is scored, what earns a 10-8, and the myths that cause most of the arguments.

The same must system, a different sport

MMA borrowed boxing's 10-point must system. The judge must give 10 points to the winner of each round and fewer to the loser. If you want the boxing version first, we covered it in how a boxing round is scored.

The big difference is what counts as winning. Boxing judges weigh punches. MMA judges weigh everything that happens in a fight with punches, kicks, knees, elbows, takedowns and submissions. That needs a clearer hierarchy, and the Unified Rules provide one.

There are three judges, each scoring every round on their own card. Rounds are five minutes. Most fights are three rounds; title fights and main events are usually five.

The criteria, in order

Judges work through the criteria like a set of gates. They only move to the next one if the previous one is genuinely level.

Effective striking and grappling

This is the gate that decides nearly every round. Effective striking means legal strikes that do something to the opponent: they hurt, they slow, they wear down. Effective grappling means takedowns, reversals (going from the bottom position to the top), advancing to a better position, and submission attempts that genuinely threaten.

The word that matters is impact. Under the current guidance, judges should ask which fighter did more to bring the other closer to defeat. A clean head kick that wobbles someone outweighs a pile of light jabs. A takedown that leads to heavy ground strikes outweighs one where the opponent stands straight back up.

Striking and grappling are weighed together, not separately. A judge does not add up "striking points" and "grappling points". They look at the whole round and ask whose offence had the bigger effect.

Effective aggressiveness

Only if striking and grappling are completely level do judges look at effective aggressiveness: making attempts to finish the fight. Pressing forward is not enough. Chasing an opponent around the cage without landing is not effective. The fighter has to be actively hunting the finish.

Fighting area control

Last of all comes fighting area control: who decided where the fight happened. Pushing an opponent to the fence, keeping the fight in the middle, choosing whether it stays standing or goes to the mat. This is the tiebreaker of tiebreakers. If a judge is reaching for it, the round was very close indeed.

Why "damage" matters so much

You will hear commentators say "damage wins rounds". That is the plain-English version of the first criterion. Impact is the core of effective striking and grappling, and visible signs that a fighter has been hurt are some of the strongest evidence a judge has.

Why weight it so heavily? Because the purpose of MMA is to finish the opponent, by knockout, submission or stoppage. A round should go to the fighter who came closer to that goal. Damage is the clearest evidence of who came closer.

Two things are worth noting. First, impact is not only about cuts and swelling. A fighter whose legs buckle, who is visibly slowed by body shots, or whose movement is compromised by kicks to the leg is taking damage too. Our piece on the calf kick shows how leg damage builds across a fight even when it looks quiet. Second, some fighters mark up easily and some do not. Judges are asked to weigh the effect of the strikes, not to reward whoever has the more colourful face.

10-9, 10-8 and 10-7

The 10-9 round

The standard round. One fighter won it, by any margin. Close rounds and clear rounds are both 10-9.

The 10-8 round and the 2017 update

For years, 10-8 rounds were handed out very cautiously in MMA. That made it hard for a fighter who dominated one round and narrowly lost two others to win on the cards, even if they had done far more damage overall.

In 2017, the Association of Boxing Commissions adopted updated judging criteria that gave judges a clearer framework for 10-8 rounds. Judges assess three things:

• Impact. Did one fighter's strikes or grappling clearly diminish the other's ability to fight?
• Dominance. Was the losing fighter forced to spend the round defending, escaping and surviving, with little or no offence of their own?
• Duration. How much of the round did that impact or dominance last?

When a fighter wins a round with significant impact, and dominance or duration are also present, a 10-8 is meant to be on the table. The point was to encourage judges to use the full scale, rather than to save 10-8 for rounds where the fight was nearly stopped.

The 10-7 round

A 10-7 is reserved for overwhelming dominance and impact across the round: the losing fighter was in serious trouble repeatedly and offered essentially nothing back. You will rarely see one. Most rounds that bad end in a stoppage.

The 10-10 round

Even rounds are allowed but strongly discouraged. As in boxing, the judge's job is to find a winner, and in five minutes of MMA there is almost always something to separate them.

The common misconceptions

"He got the takedown, so he won the round"

A takedown is effective grappling, but it is one action. What happens after it matters more. If a fighter scores a takedown in the first minute and the opponent stands up thirty seconds later, then outstrikes them for the remaining time, the takedown alone should not win the round. Takedowns earn credit for the position and the threat they create. If they create nothing, the credit is small. There is more on how wrestlers and grapplers try to turn position into scoring in our wrestling vs jiu-jitsu breakdown.

"She had four minutes of control time"

Control time is a statistic, not a criterion. Holding a fighter against the fence or lying on top of them is only effective grappling if it is doing something: landing strikes, advancing position, hunting submissions. Four minutes of stalled top position against an opponent who is landing elbows from the bottom may not win the round at all.

"He was moving forward the whole time"

Forward movement is not effective aggressiveness on its own, and aggressiveness only counts if striking and grappling are level anyway. A fighter can walk forward for five minutes and lose the round to an opponent who counter-punches cleanly off the back foot.

"She landed more strikes"

Strike counts are useful, but they do not weigh strikes. Twenty light leg kicks and one punch that drops someone are not equal. Judges are told to weigh impact, so the round can go to the fighter who landed less.

"The submission attempt doesn't count because it wasn't finished"

It does count, if it was a genuine threat. A deep choke that forces the opponent to fight desperately to escape is effective grappling. A loose attempt that never troubled anyone is not.

A hypothetical three-round card

Here is an invented fight between two invented fighters, Red and Blue. This is a hypothetical example only, to show how 10-8 rounds and split opinions combine. Each cell is written as Red–Blue.

The story: Red wins a competitive first round on the feet. In round 2, Blue lands a takedown, moves to mount (sitting on the opponent's chest) and lands heavy ground strikes for most of the round. In round 3, Red lands more on the feet but Blue scores a late takedown and threatens a choke.

• Judge 1 gave round 2 as 10-8 because Blue's ground work had clear impact, dominance and duration. Red wins rounds 1 and 3, but the 10-8 brings the card level at 28–28.
• Judge 2 saw round 2 as a clear Blue round but not a 10-8, perhaps judging that Red defended well enough to limit the impact. That card goes to Red, 29–28.
• Judge 3 agreed on the 10-8 and also gave round 3 to Blue, weighing the late takedown and choke threat above Red's striking. That card goes to Blue, 27–29.

One card each way plus a draw: a split draw. Notice how much hangs on round 2. A single judgement call on whether it was 10-8 or 10-9 moves Judge 1's card from a draw to a Red win, and that alone would have turned the result into a split decision for Red.

This is why we write a short note on every round when we score a fight. When cards disagree, the disagreement is usually about one or two rounds, and the note tells you why.

The bottom line

MMA judging is not a mystery. Effective striking and grappling decide almost every round, and impact is the heart of it. Aggressiveness and cage control only come into play when everything else is level. Since the 2017 update, a dominant, damaging round should be scored 10-8, which gives judges a way to reward the fighter who came closest to a finish.

Takedowns, control time, forward pressure and strike counts are all clues. None of them is the answer by itself. Score the next card you watch with the hierarchy in hand, write one line per round, and compare it with the officials. You will argue with fewer cards, and argue better with the ones that deserve it.
