Jammers score one point every time they lap an opposing Blocker. A Jammer laps a Blocker if they pass that opponent twice in a row (without that opponent having passed that Jammer), but score a point only if the lapping pass is earned (see Section 2.5). If an opponent is lapped but a point is not scored (because the lapping pass was not earned), the Jammer may yield position to that opponent and re-pass them, earning a pass, to score on that opponent.
Only Blockers can be scored upon. All Blockers are considered to be on the same trip, including former Jammers who have passed the Star.
Points are grouped by trips through the Pack. One trip through the Pack ends, and the next begins, when the Jammer exits the front of the Engagement Zone (or, if no Pack can be defined, when the Jammer is more than 20 ft ahead of the foremost in-bounds member of the previous Pack). Upon completion of a trip through the Pack, the Jammer’s score for that trip can no longer be altered by dropping back to re-pass any opponents the Jammer did not score upon on that trip.
If a Jammer enters the Engagement Zone from the front, they return to their previous trip until they exit the Engagement Zone from the front again. A Jammer cannot, however, fall behind by more than one trip. Whenever a Jammer exits the Engagement Zone from the front, they return to their latest trip. If a Jammer falls behind their initial trip through the Pack, passes on Blockers do not count toward scoring or lapping until they return to their initial trip through the Pack.
When a Jam ends, whatever trip the Jammers are on is considered to have been “completed” by the Jam ending.
Opponents can only avoid being scored upon by remaining ahead of the Jammer, or by ensuring that when they are passed, the pass is not earned. If a Jammer completes a trip through the Pack without the opportunity to earn a pass on an opponent, the Jammer is said to have earned a pass on that opponent. This includes but is not limited to:
Opponents who are ahead of the Engagement Zone when the Jammer completes their trip through the Pack by exiting the front of the Engagement Zone
Opponents who are ahead of the Engagement Zone at the end of the Jam when the Jammer is on a scoring trip and ahead of the rearmost Pack Blocker
Any Not-On-the-Track Point (see Section 2.5) that the Jammer cannot earn because they complete their trip through the Pack without the opportunity to earn a pass on any opposing Blocker (which would earn them a pass on the off-the-track opponents)
Opponents who are out of play behind the Pack, if a Jammer reenters the track from the Penalty Box in front of that Blocker
If a Jammer renders themself unable to score points–for example, by committing a penalty or by removing the Star–any not-on-the-track points they would have earned while unable to score are earned once they become able to score again. If an opponent’s action renders the Jammer unable to score–for example, a Jammer who is blocked out of bounds–the Jammer continues to score Not-On-the-Track points as usual.
When a Jammer is penalized, they are considered to no longer be on the track (even if they are physically still on the track). Accordingly, a penalized Jammer cannot earn passes on any further opponents until that Jammer completes their penalty. Upon release from the Penalty Box, a Jammer returns to the same trip through the Pack, having scored on (and/or being in position to score on) the same Blockers.
The Official Score is that which is reported and visible to teams, Officials, and spectators. If a point is awarded (or denied) in error, or if a Jammer Referee has reported a score incorrectly, the score may be corrected no later than the end of the Jam after the one in which the error occurred. If there are fewer than 2 minutes in the game remaining on the period clock, score corrections must be made before the start (rather than the end) of the Jam after which the error occurred.
However, points awarded (or denied) correctly, given the information available at the time, may not be taken away (or awarded) later. For example, a Jammer who exits the Engagement Zone and is awarded four points has earned those points, even if upon review they were found to have committed a penalty two trips prior (and thus would not have been able to earn those points).
