Scoring & Stats Explained

Volleyball stats measure how players and teams perform. The core stats are the kill, ace, dig, assist, block and error. The headline efficiency number is hitting percentage = (kills − attack errors) ÷ total attack attempts. To work it out from your own numbers, use the Stats Calculator.

The core stats

Every rally scores a point for one team (rally scoring), so every stat below is tied to how rallies are won or lost. For sets, matches and tiebreaks, see Rules for Beginners.

  • Kill: an attack that ends the rally in your team's favor — the opponent cannot return it.
  • Ace: a serve that scores directly: it lands untouched, or the receiving team can't keep it in play.
  • Dig: keeping an opponent's attack in play (serve receive does not count as a dig).
  • Assist: the touch — almost always the set — that leads directly to a teammate's kill.
  • Block: a block that wins the point directly (a "stuff"). One blocker gets a solo block; when two or three block together, each gets a block assist. Touching the ball on the block without scoring is not counted as a block.
  • Error: a fault that gives the opponent the point — a service error, an attack into the net or out, a ball-handling fault, and so on. Only attack errors count in hitting percentage.
  • Pass rating: a coaching convention, not an FIVB rule. Each serve-receive pass is scored 0–3 (3 = perfect, the setter has every option; 2 = good, some options; 1 = poor, only one option, usually a high set; 0 = no playable pass: an ace, a shank or an overpass), and the average shows passing quality. A 0 is a coaching grade, not a box-score stat: an aced pass also counts as a reception error (RE), but an overpass that stays in play does not. See serve receive.

Hitting percentage

Hitting percentage (also called attack efficiency) is the standard measure of how effective a hitter or team is. The formula is:

Hitting % = (kills − attack errors) ÷ total attack attempts

Under NCAA-style accounting, attack errors include faults during an attack attempt, such as an illegal contact or back-row attack, and out/net/blocked attacks that end the rally in a point for the opponent. Ordinary nonattack setting and serving errors are separate. Attempts = kills + attack errors + attacks kept in play; scoring tips and dumps count too. An overpass or survival free ball kept in play is not an attempt. If it scores directly, count a kill and attempt; a free-ball fault may be an attack error unless the preceding touch made it unplayable.

Worked example

Suppose a hitter records 15 kills and 3 attack errors on 40 total attempts:

(15 − 3) ÷ 40 = 12 ÷ 40 = 0.300

That is read as "a .300 hitting percentage." Because attack errors are subtracted, the number can be negative when a player makes more attack errors than kills; the scale runs from −1.000 to 1.000. Anything around .300 and above is generally considered strong, though it varies by level and by position — middles often post higher percentages on quick sets than outside hitters.

Side-out percentage

Side-out % is the share of rallies a team wins while receiving serve. A high side-out percentage means the team reliably converts the opponent's serve into a point of its own, which is the foundation of consistent play. Its counterpart, point-scoring (or serving) percentage, measures rallies won while serving.

Reading a box score

Match reports and stat sites use short abbreviations. The common ones:

KKills
EAttack errors
TATotal attack attempts
PCTHitting percentage
AAssists
SAService aces
SEService errors
REReception (serve-receive) errors

PTSPoints: kills + aces + solo blocks + half the block assists

Season stats are often shown per set (for example, kills per set = kills ÷ sets played), so players who played different numbers of sets can be compared fairly.

Deep dive: reading the numbers

Why hitting percentage beats raw kills

Kills alone don't tell the whole story — a hitter with many kills but many errors may be hurting the team. Hitting percentage rewards scoring and punishes attack errors on the same scale, so it reflects true efficiency. That is why coaches track it per set and per rotation, not just as a season total.

Team stats vs individual stats

The same stats aggregate to the team: team hitting percentage, total blocks (solo blocks plus half the block assists), total digs, and service aces. Side-out % and point-scoring % describe the team as a whole across its two phases — receiving and serving — and together they explain most of why a set was won or lost.

Where stats come from

Each stat counts a specific outcome of a rally: a kill and an ace end it in your favor; an error hands the point to the opponent. The rules decide what counts as a fault. If any term here is unfamiliar, the glossary defines them all in one place.

From five actions to a useful tally

This fictional teaching sample shows five actions, not a whole match. Decide what each action counts as before using a calculator. The accounting follows NCAA statistics; another competition or data provider may use its own definitions.

ActionKillsAttack errorsAttempts
A deliberate tip lands for a point.101
An intentional attack is dug and the rally continues.001
The referee calls an illegal contact during an attack attempt.011
A serve-receive overpass is kept in play by the opponents.000
A free ball sent only to keep play alive is kept in play.000

Totals: 1 kill, 1 attack error, 3 attempts. Hitting efficiency = (1 − 1) ÷ 3 = .000; kill percentage = 1 ÷ 3 = 33.3%. Those are different measures. The in-play overpass and survival free ball do not add attempts.

Try these totals in the stats calculator. For your team, use a fuller sample and note the context before choosing one practice goal; five actions cannot diagnose a player. The simple observation sheet is useful when detailed tallying would distract from watching.

Frequently asked questions

How do you calculate hitting percentage in volleyball?

Hitting percentage is (kills minus attack errors) divided by total attack attempts: (15 − 3) ÷ 40 = .300. NCAA-style attack errors include faults during an attack attempt, not ordinary serving or nonattack setting errors. A survival free ball or overpass kept in play is not an attempt; a direct point is a kill and attempt. A free-ball fault can be an attack error unless an unplayable preceding contact caused it.

What is the difference between a kill and an ace?

A kill is an attack that scores directly; an ace is a serve that scores directly: it lands untouched, or the receiving team can't keep it in play. Both end the rally in your favor, but a kill comes from an attack and an ace from a serve.
