Volleyball stats explained, from kills to points per set

A volleyball box score records both rally-ending events, such as kills and aces, and plays that keep rallies alive, such as digs. Those numbers are not interchangeable: an assist helps create a kill, but it does not add another point to the scoreboard.

The definitions and formulas below follow the 2026 NCAA Volleyball Statisticians’ Manual for indoor volleyball. For beach volleyball or another competition, check the statistics provider’s legend rather than assuming every category uses the same convention.

The main volleyball stats and abbreviations

Read the column heading as well as the abbreviation. For example, E in the attack section means attack errors—not every mistake a player makes.

Stat	Meaning	What it tells you
K — Kills	Attacks that directly produce a point, including attacks that lead directly to an opponent’s blocking error	Attacking point production, not necessarily hard spikes
E — Attack errors	Failed attacks, including balls hit out and attacks blocked for a point	Points conceded during attack attempts
TA — Total attacks	Kills + attack errors + attacks kept in play	Attacking workload; not every ball sent over the net counts
PCT — Hitting percentage	(K − E) ÷ TA	Net attacking output per attempt
A — Assists	Passes, sets or digs to a teammate who then records a kill	Successful connections to attacking points—not the number of sets attempted
SA — Service aces	Serves that directly produce a point	Direct scoring from service; receiver contact does not rule out an ace
SE — Service errors	Serving faults, such as serving out or into the net	Points conceded on serve
RE — Reception errors	Errors associated with an opponent’s ace	Direct reception failures, not all poor passes
D or DIG — Digs	Opponent attacks successfully kept in play	Defensive saves against attacks—not serve receptions
BS / BA — Block solos / block assists	Successful point-ending blocks by a lone blocker or cooperating blockers	Blocking credits; a block deflected and successfully kept in play earns neither
PTS — Points	K + SA + BS + ½ BA	Credited scoring contributions, not the team’s full scoreboard total

These categories come from the NCAA manual’s definitions and calculated categories. A player can earn an assist without using an overhead set, and a successful block can award a block assist to each cooperating blocker even if only one touches the ball.

Read one player’s line

Consider this illustrative match in which the player appeared in all four sets:

12 K, 4 E, 30 TA, 1 SA, 1 BS, 4 BA

The player’s hitting percentage is:

(12 − 4) ÷ 30 = .267, rounded to three decimal places.

The kill percentage is different: 12 ÷ 30 = 40%. Hitting percentage subtracts attack errors; kill percentage does not. The remaining 14 attempts stayed in play, because 30 − 12 − 4 = 14. For more on which contacts enter the denominator, see volleyball hitting percentage.

The player’s credited points are:

12 + 1 + 1 + (½ × 4) = 16.0 points.

Notice that blocking uses two conventions. The player has five individual block credits—one solo plus four assists—but those assists contribute only half each to the points calculation. NCAA team blocks likewise use BS + ½ BA, rather than simply adding every player’s block credits. These are the manual’s specified formulas.

Why statistical points do not equal the set score

In an illustrative 25–22 set, the winning team could have:

• 14 kills
• 2 aces
• 3 solo blocks
• 6 additional points from opponent errors, such as missed serves or attacks hit out

Its credited statistical points total 19, while its scoreboard total is 25. The six additional opponent errors complete the score. Do not count an opponent’s attack blocked for a point again among those additional errors: the same rally already supplied the block credit.

Assists and digs cannot fill that gap. If a defender digs an attack, a setter assists and a hitter kills the next ball, the team records three useful actions but wins one rally and one scoreboard point. See how volleyball scoring works for the distinction between rally points and sets won.

Compare rates, then check opportunities

Per-set statistics divide the total by sets played. The example player’s 12 kills across four sets equal 3.00 kills per set, and 16.0 points equal 4.00 points per set. That makes totals easier to compare across matches of different lengths, but it does not adjust for every opportunity: under NCAA statistical rules, even a partial appearance counts as a set played for the player’s statistical categories. See the manual’s per-set calculation rules.

For a useful first reading of a box score:

• Read kills alongside hitting percentage and attempts: volume and efficiency answer different questions.
• Read aces alongside service errors: aces alone omit points conceded. The fuller comparison is in aces versus service errors.
• Treat digs and reception errors as different categories: digs concern attacks; reception errors concern serves. A poor but playable pass may produce no reception error.

Avoid a universal “good stat” cutoff without specifying the competition, role and sample. A high rate on a few attempts is not the same evidence as sustained production across a season.
