Pass TrackerThe 3-2-1-0 Serve-Receive Rating System, Explained
The 3-2-1-0 scale is the most widely used way to grade serve receive in club and high school volleyball. Instead of "good pass" or "bad pass," you give every serve receive one number from 3 down to 0 based on how many offensive options the pass left your setter. Here is exactly what each number means, why coaches use it, and how to keep it consistent.
What each rating means
The core idea: you are grading the quality of the pass, measured by what your setter can do next, not whether you eventually won the point. A perfectly passed ball is still a 3 even if your hitter later gets blocked.
| Rating | Name | What it looks like |
|---|---|---|
| 3 | Perfect | Ball is right at the target, around 10 feet off the net. The setter is in position with every option live, including a quick middle attack. |
| 2 | Good | Setter can still run most of the offense but had to move, or the ball drifted off the net or inside. The quick middle is usually off the table. |
| 1 | Poor | Ball is kept in play but the setter is out of system or someone else has to set. You are almost certainly putting up a high, predictable outside ball. |
| 0 | Error | An ace, an overpass (a serve passed straight over the net), or a shank. No playable pass, and the serve ended the rally in the server's favor. An overpass counts as a 0 because it hands the other team a free attack, the same as an ace. |
A simple way to remember it
If numbers feel abstract to new passers, tie each one to the offense:
- 3 = run anything. All three front-row attackers plus the slide are available.
- 2 = run most things. You lose the quick, but the setter still has choices.
- 1 = free ball to them, basically. One predictable high set, easy for the other team to read and defend.
- 0 = they scored. Ace, overpass, or unplayable.
Why coaches use a number instead of "good" or "bad"
- It averages into a single stat. Numbers let you compute a passing average per player, per rotation, and per match, and chart it over a season. "Good/bad" cannot be averaged into a trend.
- It captures the middle. Most passes are not perfect or disasters, they are 2s. A two-bucket system throws away the exact information that separates a decent passing team from a great one.
- It maps to your offense. The scale is really a measure of how often your full offense is available, which is the thing that actually wins rallies.
Rate on the 3-2-1-0 scale in one tap
Pass Tracker is built around this exact scale. During the rally you tap 3, 2, 1, or 0 for the pass that just happened, and it keeps the running average, the in-system percentage, and per-player and per-rotation breakdowns for you, live. Free while in beta.

The whole scale hinges on one idea: in system means the pass was good enough to run your normal offense, and out of system means it was not. In 3-2-1-0 terms, 2s and 3s are in system and 1s are out of system (a 0 never got a pass up at all).
That is why coaches track in-system percentage next to the average: it is the share of serve receives graded 2 or 3. If your team is in system on 60% of serve receives, your setter gets to run the full offense 6 times out of 10. Raising that percentage often matters more than nudging the raw average, because it directly decides how often your middles and quick attack are options.
Common variations you will see
- The 4-point (0 to 4) scale. Some programs, and many college and national-team stat systems, split the top so a "perfect" and a "playable-but-off" pass are further apart. More precise, slightly slower to grade live. (An overpass is still a 0 on this scale too.)
- Plus/minus systems. A few coaches grade with symbols (#, +, -, =) instead of numbers. It converts to the same idea; numbers are just easier to average.
Pick one and never change it mid-season. A 2.1 average only means something if every rep all year was graded on the same scale by the same standard. Mixing a 0 to 3 average with a 0 to 4 average, or grading loosely in practice and strictly in matches, makes the trend line meaningless.
How to grade consistently
- Grade off the setter's position, not the outcome. Decide the number the instant the ball leaves the passer, based on where it is going, before you see whether the hitter scores.
- Have one grader per court. Two coaches will always drift on where "2 ends and 1 begins." One consistent set of eyes beats two accurate ones.
- Anchor your 2 vs. 3 line. Agree as a staff on the target box that counts as a 3, and hold it all season.
- Grade every rep, not just matches. The scale is most useful as a practice feedback tool. Passers improve when they see the number climb drill to drill.
The bottom line
The 3-2-1-0 scale grades each serve receive by how much offense it leaves available: 3 runs everything, 2 runs most, 1 is a predictable free ball, 0 is a point for the server. Pair the average with in-system percentage, pick one scale and grade it the same way all season, and the number becomes a real coaching tool instead of a guess.
