Penalty Enforcement: A Study Guide for the Crew

Rules Mechanics

Reflects the 2025 NFHS rules year. Built from the 2025 NFHS Football Rules Book (Rules 6, 7, 8, 9 and 10, and the penalty summary). Last checked August 27, 2026.

A working summary of NFHS penalty enforcement — what the foul was, where it happened, and where the ball ends up.

How to use this page

Penalty enforcement is the part of officiating that is almost entirely learnable. Judgment on holding takes years. Knowing where to walk from takes an evening with a diagram and a few dozen repetitions.

This guide is organized the way the decision actually gets made on the field:

Vocabulary — the handful of terms every enforcement decision depends on.
All-but-one — the single principle that resolves most fouls.
The five-question checklist — what the referee runs through before signaling.
Situation by situation — running plays, passes, kicks, change of possession, dead-ball, multiple fouls, carryovers, trys.
Crew mechanics — flag, report, signal, enforce.
Penalty distances — the 5/10/15-yard groupings.

Enforcement is a crew responsibility, not a referee responsibility. When a penalty gets administered wrong, everyone wearing stripes owns it. The umpire has to know the spot and the distance. The head line judge has to know the down and control the chains. The wings have to know what to tell their coaches. Every one of those people needs this material.

1. Vocabulary

Everything downstream depends on getting these right, so it's worth being pedantic about them.

Status of the ball

There are only two possibilities, and the answer determines everything else.

Live ball — from the moment the ball is legally snapped or free kicked until the down ends.
Dead ball — the interval between downs.

Types of fouls

Type	When it happens	How it's enforced
Live-ball foul	While a down is in progress	Per all-but-one or the specific penalty statement
Foul simultaneous with the snap	Illegal motion, illegal shift, illegal formation	Ball stays live; previous spot; down repeated
Dead-ball foul	After the down ends, before the next snap or free kick	Succeeding spot; the down counts
Fouls that prevent the snap	Delay of game, false start, encroachment, illegal snap	Succeeding spot; down remains the same
Live-ball foul enforced as a dead-ball foul	Unsportsmanlike and nonplayer fouls, whenever they occur	Treated as if they happened after the play ended

That last row is the one that trips people up. An unsportsmanlike foul during a live ball does not combine with a live-ball foul to make a double foul. It gets tacked on separately, in order of occurrence.

Types of plays

Once the ball is live, the down is made up of one or both of these:

Loose-ball play — the action during:

a free kick or scrimmage kick,
a legal forward pass,
a backward pass, including the snap,
an illegal kick or a fumble by Team A from in or behind the neutral zone, before any change of possession,
plus any run that preceded one of the above.

That last clause matters more than any other sentence in this section. If the quarterback scrambles for eleven yards and then throws a legal forward pass, the scramble is part of the loose-ball play. A hold during the scramble is a loose-ball play foul with previous-spot enforcement — not a running play foul.

Running play — anything else. Any action while a player is in possession that isn't part of a loose-ball play.

A single down can contain several running plays. A runner fumbles, a teammate picks it up and runs, he throws a backward pass, someone else runs: that's multiple running plays, each with its own end of run.

The spots

Previous spot — where the ball was last put in play by snap or free kick. Common enforcement spot, so the crew must protect it. This is why the chain crew doesn't move the box when a flag is down.
Succeeding spot — where the ball will next be put in play. Usually the dead-ball spot, but it moves if a penalty relocates the ball.
Dead-ball spot — under the forward point of the ball when it became dead by rule.
Spot of the foul — where the foul happened. This is why the covering official's flag placement matters; if the flag is off, pick it up and move it decisively rather than nudging it with a foot.
End of the run — where the runner was downed, went out of bounds, fumbled, threw a backward pass, or threw an illegal forward pass. Note that the end of the run and the end of the running play can be different yardlines.
Post-scrimmage kick (PSK) spot — where the kick ends. See the kicking section.
Basic spot — a reference point, not a fixed location. It is one of a short list: the previous spot, the end of the run, the spot of the foul (for the fouls listed in 10-4-4), the succeeding spot (10-4-5), the PSK spot, or — after a change of possession — the 20-yard line or the goal line (10-4-7, 10-4-8). Nothing else.
Enforcement spot — the spot you actually walk from, derived from the basic spot by the all-but-one principle.

2. The All-But-One Principle

Some penalties name their own enforcement spot. Encroachment, illegal motion, illegal shift, illegal formation: always previous spot, no thinking required.

When the penalty statement doesn't name a spot, all-but-one decides it. It's also called the three-and-one principle, and the name is the mnemonic: of the four possible cases, three enforce from the basic spot and one doesn't.

Step one: find the basic spot

Play type	Basic spot
Loose-ball play (legal forward pass, kick play without PSK, backward pass or fumble behind the neutral zone)	Previous spot
Running play	End of the run
Scrimmage kick play where PSK applies	PSK spot (end of the kick)

Kick returns, interception returns, and other post-change action have no neutral zone, so they are running plays and the basic spot is the end of the run.

Step two: apply the grid

Two teams, two locations relative to the basic spot, four combinations:

Who fouled	Where	Enforce from
Team not in possession	Behind the basic spot	Basic spot
Team not in possession	Beyond the basic spot	Basic spot
Team in possession	Beyond the basic spot	Basic spot
Team in possession	Behind the basic spot	Spot of the foul ← the "one"

Said plainly: the defense always gets the basic spot. The offense gets the basic spot unless it fouled behind it, in which case it eats the spot of the foul.

One refinement. On a running play the line of scrimmage matters as well as the end of the run, and this is the part most often taught the old way. A foul by the offense behind the line of scrimmage, on a run that ends beyond the line, comes back to the previous spot — not the spot of the foul (10-4-2e). The spot of the foul is the enforcement spot when the offense fouls beyond the line of scrimmage but behind the end of the run (10-4-4e), and when the team in possession fouls behind the end of the run after a change of possession (10-4-4c).

Step three: check the consequences

If the enforcement spot lands in the fouling team's own end zone, acceptance produces a safety.
Half-the-distance applies whenever the penalty distance would take the ball more than halfway to the goal line.
Check whether the penalty carries loss of down or an automatic first down before you offer options.

Worked example. First and 10 for A from its own 20. A1 carries to the 35. A2 holds.

Hold at A's 25 → beyond the line of scrimmage, behind the end of the run (A's 35) → enforce from the spot of the foul → first and 15 from A's 15.
Hold at A's 15 → behind the line of scrimmage, run ended beyond it → enforce from the previous spot → first and 20 from A's 10.
Hold at A's 40 → beyond the end of the run → enforce from the basic spot → first and 5 from A's 25.
Hold in A's own end zone → enforcement spot is behind the goal line → safety if accepted.

Same foul, same down, four different results. That's the whole reason flag placement matters.

3. The Five-Question Checklist

Every enforcement, in order:

Live ball or dead ball? Dead-ball fouls skip everything below — succeeding spot, down counts, administer in order of occurrence.
Loose-ball play or running play? Remember that a run preceding a pass or kick belongs to the loose-ball play.
Where is the basic spot? Previous spot, end of the run, or PSK spot.
Who fouled, and where relative to the basic spot? Run the grid.
Does the offended team have a real choice? If not, don't burn time consulting a captain.

Then: enforce, verify the down and the chains, signal, and get the ball ready.

When you don't need to ask the captain

Some penalties are automatic acceptances. Consulting a captain about them is dead time that invites sideline noise.

Dead-ball fouls — the yardage is free, and there's no down at stake.
Fouls after a change of possession — same logic; nothing to replay.
Anything that wipes out a score, a turnover, or a first down against you.
Tack-on fouls — defensive facemask on a running play, roughing the passer on a completion.
Penalties carrying loss of down or an automatic first down.

Declination can be equally obvious. If the play produced a first down and the penalty wouldn't, signal the refusal and move on.

When to talk to the coach instead of the captain

There are situations where the decision is strategic and the captain will just go ask the coach anyway. Save everyone the delay and have the wing official on that side present the options directly:

Running into the kicker on a punt: accept and take fourth-and-short, or decline and take the field position?
Free kick out of bounds untouched: rekick after a 5-yard penalty, 5 yards from the succeeding spot, or the ball 25 yards beyond the previous spot?
A defensive foul on a try, which moves the ball to the 1½: a team not going for two may prefer its practiced kick distance.
A team intentionally taking delay of game before a punt to gain coffin-corner room — the opponent may want to decline and spoil it.

These are exactly the situations where a crew that knows enforcement cold looks sharp and one that doesn't looks lost.

4. Situation by Situation

4.1 Fouls on running plays

Straight all-but-one.

Offense. Enforce from the end of the run, unless the foul was behind the end of the run and beyond the line of scrimmage — then the spot of the foul. A foul behind the line of scrimmage on a run that ends beyond it comes back to the previous spot. A foul in the offense's own end zone is a safety on acceptance.

Defense. Always the end of the run. This is the familiar "tack-on": the runner gains 15, the defender grabs the facemask at any point during the run, and the 15 goes on the end.

Fouls at the snap. Illegal motion, illegal formation, illegal shift, a numbering violation — previous spot, repeat the down.

Illegal forward passes are running-play fouls under NFHS, enforced from the spot of the pass (7-5-3, 10-4-4b). A pass thrown after a change of possession is 5 yards; a pass from beyond the neutral zone, a second forward pass, and intentional grounding are 5 yards plus loss of down (7-5-2). If the pass is thrown from the offense's own end zone, accepting the penalty makes it a safety (8-5-2c); declining it is a safety only when the result leaves the passer in possession at the spot of the pass and the passing team forced the ball into its end zone. The way to remember spot-of-the-pass enforcement is that the runner keeps whatever he legally earned before he threw it.

Two related notes: pass interference and roughing the passer are not possible on an illegal pass, though contact can still be a personal foul. And if the defense also fouls on a down containing an illegal forward pass, the penalties cancel.

Fouls by the offense in the opponent's end zone before a touchdown are enforced from the goal line, because the goal line is the end of the run.

4.2 Fouls during passes, fumbles, and backward passes

The basic spot for a loose-ball play is the previous spot. Start there, then check whether the offense fouled behind it.

Legal forward pass, incomplete. Both teams' fouls come back to the previous spot — except an offensive foul behind the previous spot, which is enforced from the spot of the foul.

Roughing the passer on a completed pass is enforced from the dead-ball spot when the dead-ball spot is beyond the neutral zone, Team A has the ball at the end of the down, and there was no change of possession. Enforce from the previous spot instead if any of that fails — a change of possession, a dead-ball spot behind the neutral zone, a touchback — and for an incidental face mask on the passer. A screen pass caught behind the line and tackled there gets previous-spot enforcement, not a tack-on.

Fumbles and backward passes. The location of the loose ball relative to the neutral zone drives the basic spot:

Loose ball originates behind the neutral zone → basic spot is the previous spot. Offensive fouls behind it go to the spot of the foul; in the end zone, safety.
Loose ball originates beyond the neutral zone → the spot of the fumble or backward pass becomes the reference. Defensive fouls before or during the loose ball enforce from there; offensive fouls behind it and beyond the line of scrimmage enforce from the spot of the foul (10-4-4e); an offensive foul behind the line of scrimmage goes back to the previous spot (10-4-2e); offensive fouls beyond the fumble spot enforce from the spot of the fumble.

A consequence worth internalizing: a defensive foul during a fumble your own team recovers usually can't be tacked onto the end of the recovery, because enforcement runs from the spot of the fumble. Teams often decline it.

4.3 Fouls on free kicks

Fouls during the kick (before possession) — previous spot. Accepted means a rekick. One exception (10-4-2 EXCEPTION): for a K foul other than kick-catching interference that occurs before the kick ends, when K will not be next to snap, R may instead take the yardage from the succeeding spot and keep the ball.
Fouls before the ball is kicked, such as encroachment — dead-ball fouls, previous spot.
Fouls after the receivers gain possession — running-play fouls, all-but-one.

Use actual possession, not "the ball reached him," to decide which side of the change a foul falls on.

Both teams foul. If both fouls precede the change of possession, they cancel and the kick is replayed — no options. If the receivers gain possession with clean hands and then foul, they can decline the kicking team's foul, keep the ball, and take their own penalty.

Free kick out of bounds untouched. The receiving team picks one of three: a 5-yard penalty and a rekick, 5 yards from the succeeding spot, or the ball at the inbounds spot 25 yards beyond the previous spot — that last one only when the previous spot is on the midfield side of R's 25. The older "take it where it went out of bounds" option is gone, so read 6-1-9 before you offer choices. If the kick crosses the goal line it's a touchback and there's no foul at all.

Fair-catch signals. An invalid or illegal fair-catch signal is a 5-yard foul. Note that an illegal signal does not kill the ball; the play continues, and the penalty is enforced afterward under the ordinary rules for a foul by the receiving team during a kick.

4.4 Fouls on change-of-possession plays

The core concept is clean hands: a team that fouled at any point during the down cannot keep the ball it gained later in that down. Once you foul, your hands stay dirty for the rest of the down.

Offense fouls before the change. The defense must decline to keep the ball.
Defense fouls before the change. The defense can't keep the ball. It goes back to the offense, enforced from the spot of the fumble or backward pass — or from the previous spot if the loose ball was behind the line.
Each team fouls. The team last gaining possession may keep it only if it did not foul before that final change, and only by declining the opponent's penalty (nonplayer and unsportsmanlike fouls excepted).

Segment thinking makes double-foul-with-change situations tractable. Break the down into segments at each change of possession: everything before the first change is segment one, everything before the second change is segment two, and so on. Then ask who fouled in which segment. If both teams fouled in segment one, the penalties cancel and the down is replayed — neither team got the ball clean.

End zone cases. After a change of possession, remember that the team designations don't change but the roles do — Team A is now the defense.

Play results in a touchback → basic spot is the 20.
Play results in a safety → basic spot is the goal line.
The opponent forced the ball into the end zone, and the related run is followed by a loose ball → basic spot is the 20, regardless of where the loose ball becomes dead (10-4-7).
The team in possession forced the ball into its own end zone, and the opponent fouls during the running play → basic spot is the goal line (10-4-8).
If both the foul and the dead-ball spot are in the field of play, ordinary all-but-one.

The force rule decides safety vs. touchback: if the team in possession put the ball into its own end zone, a downing there is a safety; if the opponent forced it there, it's a touchback.

Watch for the case where the team in possession fouls in its own end zone during a return that ends in the field of play. The result of the play is neither safety nor touchback, but accepting the penalty puts the enforcement spot in the end zone — and that's a safety.

4.5 Fouls on scrimmage-kick plays and PSK

Kicking team fouls from the snap until the kick ends: previous spot, unless the foul was behind the previous spot, in which case spot of the foul. In the kicking team's own end zone, a safety on acceptance. When K will not be next to snap, R may instead take the penalty (other than for kick-catching interference) from the succeeding spot and keep the ball (10-4-2 EXCEPTION).

Kick-catching interference by the kicking team gives the receivers a choice: accept the result of the play, take an awarded fair catch after a 15-yard penalty from the spot of the foul, or take 15 yards from the previous spot and replay the down (6-5-6 PENALTY).

Post-scrimmage kick enforcement applies when all of these are true:

the foul is by the receiving team, and isn't an illegal-substitution or illegal-participation foul that occurs at the snap;
it occurs before the kick ends;
it occurs beyond the expanded neutral zone;
the kick crosses the expanded neutral zone;
the down is not a try or a successful field goal;
the kicking team will not be next to put the ball in play.

If PSK applies, the basic spot is the end of the kick — where a player gains possession or where the kick is declared dead. A kick that breaks the plane of the receiving team's goal line ends at the 20. Receiving-team fouls behind the PSK spot are spot fouls. If PSK doesn't apply, receiving-team fouls before the kick ends get previous-spot enforcement.

The practical effect of PSK: the receiving team keeps the ball and takes the penalty from the end of the kick, rather than the kicking team getting a replay of fourth down. Missing PSK is one of the most common enforcement errors in high school football, and it's expensive — it hands a team a possession it shouldn't have.

Live-ball fouls after the kick ends are simply running-play fouls.

First touching is not a foul, but it behaves like one procedurally. It occurs when a kicking team player touches a scrimmage kick beyond the expanded neutral zone before any receiving team player touches it beyond the neutral zone, and before the ball has come to rest (6-2-5). The free-kick version is any K touching before the ball crosses R's free-kick line and before R touches it there (6-1-7). The receivers get the option of taking the ball at that spot. There is no first touching in the receiving team's end zone, because the ball is dead when it breaks the plane. First-touching privileges are cancelled if the receivers foul after touching the kick, or if any penalty in the down is accepted — so the receivers sometimes have to choose between the spot of first touching and a penalty.

4.6 Dead-ball fouls

Enforced from the succeeding spot. The down counts. Administered separately and in order of occurrence — they never combine with anything to make a double or multiple foul.

If both teams commit dead-ball fouls before the referee has finished administering the first one, the penalties offset in equal number and are not walked off (10-2-5b). Order therefore matters: a foul that arrives after the first penalty has already been enforced does not offset — it is administered separately from the new succeeding spot.

Consider: second and 5 from A's 15; A1 is stopped for no gain; B2 commits a late hit; A1 curses B2 in response while the crew is still sorting out B2's foul. The two dead-ball fouls offset, and it is third and 5 from A's 15. Now change the timing: B2's late hit has already been walked off — first and 10 at A's 30 with the chains reset — and then A1 curses B2. A1's foul is enforced from the new succeeding spot: first and 10 from A's 15.

4.7 Live-ball foul followed by a dead-ball foul

Same principle: separate, in order.

Example: first and 10 from B's 15, Team A illegally in motion at the snap, A1 breaks free and taunts pursuers at B's 5 on the way to an apparent touchdown. The motion penalty comes back to B's 20; the unsportsmanlike is enforced from there. First and 30 from B's 35, and no touchdown.

A live-ball foul by one team and a dead-ball foul by the other cannot create a double foul. Both get enforced.

4.8 Double and multiple fouls

Double foul — each team commits one or more live-ball fouls (excluding nonplayer and unsportsmanlike) such that the penalties offset. With no change of possession, they cancel and the down is replayed.

Multiple foul — one team commits two or more live-ball fouls. The offended team picks which penalty it wants. Only one is enforced.

4.9 Carryover fouls ("bridges")

"Bridge" isn't a rulebook word, but it's the useful shorthand for carrying a penalty over to the try or the next kickoff.

The scoring team may elect to have a penalty enforced on the ensuing free kick instead of on the try. This applies when:

the defense commits a live-ball foul on a play where the offense scores a touchdown, or
the offense commits a live-ball foul after a change of possession and the defense then scores.

If the offense fouled before the change and the defense then scored, the defense must decline that penalty to keep the score.

Dead-ball fouls committed after the touchdown but before the next ready-for-play, and unsportsmanlike fouls during or after the down, can go on the try or bridge to the kickoff. In effect, every foul by the opponents of the scoring team from the start of the scoring play through the ready-for-play on the try carries the same set of options.

Bridges do not reach overtime — with narrow exceptions.

A live-ball foul during a touchdown on the last timed down of the fourth quarter cannot bridge to overtime. If the scoring team wants the penalty, it goes on the try.
A live-ball foul by the opponent during a field goal or try on the last timed down of the fourth quarter can bridge to the succeeding spot in overtime.

End-of-quarter handling. If a bridge foul occurs on the last timed down of the first, second, or third quarter and the team elects kickoff enforcement, the period is extended for the try only. The kickoff is the first play of the next quarter — and after the first and third quarters, that's after the teams change ends. If enforcement of an accepted penalty on the last timed down produces a safety, the period is not extended; the teams change goals and the free kick opens the next quarter.

Overtime bridges. Penalties can bridge from one overtime series to the next and from one overtime period to the next. When they can, giving the offended captain the correct options is squarely the referee's job, and the options are not obvious — a successful field goal with a defensive foul, for instance, lets the kicking team choose a replay from the previous spot or carry the penalty to the succeeding spot in the next period.

When a touchdown ends the game. If the outcome is already decided and the try isn't needed for playoff qualification, the penalty is declined and the game is over. If the try must be played, the penalty can only be enforced on the try, and the try is the last play.

4.10 Fouls on trys

Trys mostly follow ordinary scrimmage rules, with a handful of specific outcomes:

Situation	Result
Offense fouls, try unsuccessful	No replay if the defense declines. No bridge.
Offense fouls, try successful	Defense must accept to get a replay. No replay if the foul carries loss of down.
Defense fouls, try unsuccessful	Offense must accept to get a replay. No bridge.
Defense fouls, successful try — kick or two-point	Offense may accept the penalty and replay the try, or accept the result and take enforcement from the succeeding spot: the kickoff, or the start of overtime.

Kick trys and two-point trys are treated alike here — a successful two-point try with a defensive foul carries the same replay-or-succeeding-spot choice as a kick. You cannot mix: with two defensive fouls on a successful try, the offense picks one penalty and one enforcement option. It can't take previous-spot enforcement on one and bridge the other. And a team can't be penalized twice for the same act — if you accept and replay, there's no bridge as well.

Once the referee has signaled ready-for-play on the try, the bridge option is gone. A foul after that ready signal is enforced on the try, full stop.

5. Crew Mechanics

Throwing the flag

Live-ball foul: drop the marker, hold the whistle, keep officiating the play to its end. Note the spot and the number.
If the spot of the foul might be the enforcement spot, get the flag as close to the yardline as you can. Throw it so it lands beside the players, not at them — throwing toward the action helps you read the number.
Wrong spot? Pick it up and move it immediately and definitively. Delay makes it look like manipulation; toeing it along the ground looks worse.
Dead-ball fouls and fouls that prevent the snap: whistle immediately, toss the flag straight up in front of you, give the stop-the-clock signal. Then keep watching — the fouled-against player may retaliate.
Three short whistle blasts after the ball is dead, with the stop-the-clock signal, brings the flag to the referee's attention.
If you must leave the flag to report, another official should stand over it.
If two officials have flags, talk before either reports — same foul or two fouls?

Techniques to avoid: slam-dunking the flag, throwing it at a player, waving it instead of throwing it, and looking angry while you do any of it.

No "me-too" flags. A second flag thrown to back up a partner is deceptive, contributes to a flag-happy image, and creates the possibility of two officials giving contradicting explanations of the same act. Coverage areas overlap sometimes; solidarity isn't a reason to throw.

Reporting

Every foul goes to the press box, both coaches, and the entire crew.

The covering official gets the report to the referee and the head line judge as fast as the play allows — the head line judge so the chains and box freeze, the referee so he can start the enforcement sequence.

Don't signal from your position. It's standard at higher levels and wrong at this one, because another official may have a different foul on the same snap. When two flags are down, the officials who threw them get together and agree before anything goes to the press box. If the line judge signals defensive encroachment from the wing and the crew ultimately penalizes the offense for a snap infraction, the offensive coach has a legitimate grievance. Get together, decide, report to the referee, then go explain to your coach.

Keep conferences short and keep your hands off each other. An arm around a partner's waist looks like conspiracy from the sideline.

Depth of the report is a pregame item. Some referees want "Number 49, offense, illegal motion." Others want "Number 49 cut upfield too soon." Getting the fuller version from a newer official lets the referee confirm there actually was a foul. Be especially careful with movement fouls, where the order of events decides the call, and with players on the end of the line, whose movement is less restricted than an interior lineman's.

The referee also needs to know the status of the ball at the time of the foul, and whether an involved player was an eligible receiver, on the fouls where that changes enforcement. Identify teams as offence and defence rather than by jersey colour.

A dead-ball foul before the snap is reported differently: the wing jogs slowly toward the middle of the field to report it, still watching the players he just flagged, because the player who was contacted may try to retaliate.

Explaining to coaches

The wing on the offending team's sideline reports the number and the nature of the foul. "Your man in motion cut upfield too soon" buys far more credibility than "there was illegal motion." The other wing only needs to give the nature of the foul.

If you didn't get the number, say so. Never guess. A number that turns out not to exist on that roster destroys the crew's credibility for the rest of the night.

Enforcing

Umpire. For previous-spot enforcement, return to the exact previous spot — the right yardline and the right lateral position between the hashes. Calculate the destination and walk directly to it; marching off a yard at a time looks amateurish.

Head Line Judge. Walk the penalty yardage off on your sideline while the umpire walks it off in the field — two independent counts that have to agree. Own the down number, and remember that acceptance of a penalty carrying loss of down, or declination, does not produce a replay of the previous down. If the umpire's spot and yours disagree, resolve it before the ball goes down. Then have the box and chains moved. In pregame, make clear to the chain crew that nothing moves until you tell them.

Line judge. Hold the enforcement spot until you are certain the enforcement was done correctly. Don't leave it to walk with anybody — you are the backup if the chains move prematurely or the umpire's count drifts.

Everyone not directly involved in enforcement watches players from the whistle until the ready.

A useful pregame convention: tape at the halfway point of the chain. If the box is beyond the tape, a 5-yard defensive penalty produces a first down — "five will get you one." The head line judge can flash this to the referee with a flat palm against the chest, so the referee already knows a new series is coming if the defense encroaches.

Sideline management. When the referee has a foul in front of the offending team's bench, the wing should come mark the flag so the referee can move away from the sideline rather than stand there arguing. The opposite wing can casually pace off the penalty as a backup for the umpire; the two should end up in the same place. Afterward, the wing picks up the flag and returns it to the referee in the middle of the field — again keeping the referee away from an angry bench.

Changing your mind. "When in doubt, don't throw the flag." But if you've thrown one you shouldn't have, tell the referee. It's unfair to penalize a team because you're no longer sure. Only the referee waves off a flag.

Signaling

Signals are a sentence, not a pile of words. Give them in order, distinctly, without rushing them together. Face the press box for every signal. Come to a complete stop first — don't walk through them. Pick a spot halfway up the stands, keep your head up, and keep your face neutral: you're neither pleased nor annoyed to be doing this. Don't jab the arm on the point.

You don't need to get between the hashes. If the play ended in a side zone, being clear of players is enough.

Stand up straight. Clipping and blocking below the waist require bending; almost nothing else does — including penalty declined, which is one of the most commonly hunched-over signals in the game.

Live-ball foul sequence:

The foul
Point to the offending team
The next down (or new series)
Ready-for-play, or start-the-clock — whistle simultaneously

Dead-ball foul sequence:

Dead-ball signal first
The foul
Point to the offending team
The next down (or new series)
Ready-for-play, or start-the-clock

Add signals as the situation requires — loss of down, disqualification. Disqualification goes after the foul signal and before the down. A declination is signaled after the point to the offending team.

Self-evident fouls — false start, delay of game, encroachment — don't need both a preliminary and a post-enforcement signal.

Clock help. The covering official tells the referee whether the clock starts on the ready or the snap, since the referee is already facing that way to signal the press box. The two approved signals are a rotated index finger for "wind on the ready" and wrists crossed at waist level for "don't wind". When the clock starts on the ready, the downward stroke of the start-the-clock signal can serve as the ready.

Wait for the head line judge to confirm the chains are set and the crew is in position before the ready-for-play.

Unsportsmanlike fouls and disqualifications

Every official records the number, or the position of the nonplayer — head coach, coordinator, etc.
Second unsportsmanlike foul on the same individual = disqualification. A flagrant foul, personal or unsportsmanlike, = immediate disqualification.
Only the referee gives the disqualification signal, and only while signaling to the press box. Use the approved signal — not a windup and a throw.
The calling official informs the player, then reports the number and the infraction to the referee, the coach, and the crew. Expect the coach to want more detail than usual.
Everyone records the number and the time. The calling official should write a short description for the state association report while it's fresh.
A disqualified coach must leave the stadium area before play resumes and may have no further contact with the team for the rest of the game, halftime included. Disqualified players are not required to leave the field.

6. Penalty Distances

Grouped by distance. This is a memorization aid, not a substitute for the penalty summary in the current rulebook — check yardage, loss-of-down, and automatic-first-down status there before you rely on it.

5 yards

Delay of game · illegal substitution · encroachment · false start · snap infraction · disconcerting act · free-kick infraction · free kick out of bounds · illegal formation · illegal numbering (fewer than five on A's line numbered 50–79) · illegal shift or illegal motion · planned loose-ball infraction · invalid or illegal fair-catch signal · illegally handing the ball forward (loss of down) · illegal forward pass by the offense (loss of down) · illegal forward pass by the defense · intentional grounding (loss of down) · ineligible receiver illegally downfield · illegal touching (loss of down) · helping the runner · incidental grasp of the facemask · running into the kicker or holder · attendant illegally on the field · sideline interference — a nonplayer outside the team box but not on the field (warning first, then 5 yards, then 15)

10 yards

Holding · illegal use of hands or arms · illegal block in the back · illegal block on a free kick · illegal blocking technique · interlocked blocking · runner grasping a teammate · illegally kicking or batting the ball

15 yards

Unsportsmanlike conduct by a player or nonplayer · illegal block after a fair-catch signal · kick-catching interference · forward-pass interference · illegal block below the waist · block on the free kicker or holder · clipping · chop block · tripping · illegal personal contact · charging into an opponent obviously out of the play · hurdling an opponent · grasping and twisting, turning or pulling the facemask, helmet opening, chin strap, or attached mouth guard · illegal helmet contact · targeting · illegal blindside block · horse-collar tackle · initiating contact with a helmet-less opponent · forceful contact against a defenseless receiver · roughing the passer (automatic first down) · roughing the kicker or holder (automatic first down) · roughing the snapper (automatic first down) · slapping a blocker's head · illegal personal contact in the restricted area · illegal participation · nonplayer illegally on the field · sideline interference (third and subsequent offenses) · unfair acts

Disqualification with a 15-yard penalty

Fighting by a player or nonplayer · intentionally contacting an official · striking, kicking, or kneeing · any act that is unduly rough or flagrant · a second unsportsmanlike foul by the same individual · a substitute leaving the team box during a fight

7. The Short Version

If you remember nothing else:

Two questions decide almost everything: where is the basic spot, and where did the foul happen relative to it.
Basic spot = previous spot on a loose-ball play, end of the run on a running play, end of the kick under PSK.
All-but-one = the defense always gets the basic spot; the offense gets the basic spot unless it fouled behind it.
A run that precedes a pass or kick belongs to the loose-ball play.
Dead-ball fouls are separate, in order, from the succeeding spot, and the down counts.
Clean hands: you can't keep a ball you gained after you fouled.
PSK keeps the ball with the receiving team and enforces from the end of the kick.
Signals are a sequence. Stop, face the press box, and give them in order.

Notes on sources and currency

This page is an original summary of NFHS penalty-enforcement concepts written for our members. It is not a reproduction of any published work.

Officials who want a fuller treatment — with diagrams and dozens of worked case plays — should get a copy of High School Football Penalty Enforcements Made Easy: Position by Position Responsibilities by Jeffrey Stern, published by Referee Enterprises / NASO. It is the best study aid available on this topic and it is worth buying.

Verify against the current rulebook. The enforcement concepts above are stable, but the wording and the numbers move. This page was checked against the 2025 NFHS Football Rules Book. Before you teach any of it, read the current book and your state's adaptations. The parts worth re-reading every year:

The basic-spot rules (10-4). These have been rewritten more than once, and the changes are the kind that alter where you walk from, not just how it reads.
Blocking below the waist and the free-blocking zone (9-3-2, 2-17).
The illegal personal contact list (9-4-3). Fouls get added to it and the names change.
The penalty summary. Yardage, loss of down and automatic first down all live there. Section 6 above is a memory aid built from it, not a replacement for it.
The signal chart. Signal numbers and mechanics change. Work from the current chart, and confirm which signals your state expects.
Vermont adaptations. Check for any state-specific modifications before applying anything here.
