Figure Skating Underrotation: How Jumps Are Judged and Scored

Updated: October 19, 2026

That makes underrotation in figure skating more than a question of counting turns: it is a judgment about where the jump’s rotation ends and the landing begins. Understanding what officials look for—and why close calls can divide viewers—helps explain how a seemingly tiny difference can affect a jump’s evaluation.

Landing shortfall	Classification	Protocol mark
Between ¼ and ½ rotation	Underrotation	<
½ rotation or more	Downgrade by a full rotation	<<
Exactly ¼ rotation	Quarter call: rotation counted, execution marked down	q
Less than ¼ rotation	Treated as fully rotated	none

What does underrotation in figure skating mean?

Underrotation in figure skating means a jump lands before the skater completes the rotation required for that jump. The shortfall is judged against the jump’s required turns, not simply by how the landing looks in a single photograph.

How the protocol distinguishes an underrotation from a downgrade

Two protocol symbols are used: “<” marks an underrotated jump, while “<<” marks a downgrade. The distinction is based on how much rotation is missing at landing.

• Underrotation (“<”): the jump is short by between a quarter and a half rotation.
• Downgrade (“<<”): the jump is short by half a rotation or more, so it is treated as one full rotation lower.

These thresholds describe the amount of rotation missing, not a visual impression from a still image. A frame can show the blade touching down, but it cannot by itself establish precisely how far the jump fell short; the call concerns the rotation completed by the landing.

Why can a full-turn jump be difficult to call?

A full-turn jump can be difficult to call because the key question is whether the skater has completed the required rotation when the blade first meets the ice. That instant may be hard to isolate in a brief view: the blade touches down while the skater’s body may still be turning. A visible landing position alone does not always make the exact timing clear.

What makes the landing hard to read

Take-off direction is not enough to establish how much rotation happened in the air. A skater can turn before leaving the ice, so the apparent direction at take-off does not show the airborne rotation by itself. At landing, fast rotation can compress the decisive moment: a small shortfall may be difficult to distinguish by eye.

The rules describe underrotation as a jump short by more than a quarter but less than a half rotation, and a downgrade as a shortfall of half a rotation or more. Those categories clarify what is being assessed, but they do not establish that every full-turn jump is harder to judge.

How do take-off direction and pre-rotation affect what viewers see?

Take-off direction and pre-rotation change how a jump’s rotation looks before and after it leaves the ice, so an earlier body position cannot by itself show whether the skater landed fully rotated. A Golden Skate forum excerpt argues that a skater who pre-rotates less gets more rotation in the air; it gives no numerical allowance and states no judging rule.

What the take-off reveals—and what it does not

The flip and Lutz begin from different edges: the flip uses an inside edge, while the Lutz uses an outside edge. That difference affects the direction from which rotation starts; on a Lutz, the counter-rotated take-off can make the body’s initial turn look unlike its later airborne rotation.

For either jump, assess the blade and foot at touchdown rather than relying on which way the skater faces in an earlier frame. A Lutz’s take-off direction is not a verdict on its landing: the decisive visual question is whether the blade and foot have completed the required rotation when they meet the ice.

What can a camera angle reveal—and what can it hide?

A camera angle can reveal the landing blade’s direction while hiding rotation that travels toward or away from the lens; no single view proves the whole jump. For an underrotation call, the key question is whether the skater completes the required turn before the blade touches down, not whether the blade looks aligned in one image.

A side-on replay can make the blade’s direction at landing easier to inspect, but it compresses movement along the camera’s line of sight. A view from above can clarify the skate’s direction across the ice, yet one frame may not capture the exact instant of touchdown. Each view therefore makes a different part of the landing easier to assess.

Why continuous replay matters

A replay is most informative when it shows take-off through landing without a break: viewers can follow the turn into the moment the blade meets the ice. A freeze-frame can be misleading because a turning blade may appear aligned at that instant even though the full movement shows otherwise. Screen views are evidence for discussion—not the judging rule; the distinction matters because a jump short by between a quarter and a half rotation is termed underrotated, while one short by at least half a rotation is downgraded.

When can a visual underrotation call be misleading?

A visual underrotation call can be misleading when a still image or a single camera angle hides how much the skater rotated between frames. The landing blade’s direction is useful evidence, but it must be read alongside the movement into the landing, not as a standalone verdict.

Pre-rotation before takeoff and rotation in the air are separate parts of a jump. Judging only the skater’s starting orientation can therefore overstate or understate the rotation completed airborne; the relevant question is how far short of the required full turn the jump is at landing.

Why the thresholds can be hard to distinguish

A jump short by between a quarter-turn and a half-turn is marked underrotated, while a shortfall of half a turn or more is downgraded by a full rotation. When camera perspective or gaps between frames make the landing rotation uncertain, a replay may not clearly establish which side of the half-turn threshold the jump falls on.

A single replay angle can help show blade direction and landing position, but it cannot by itself establish an official underrotation or downgrade decision.

How do underrotation and downgrade differ on the protocol?

On an ISU protocol, “<” marks an underrotated jump, while “<<” marks a downgrade: the dividing line is a shortfall of half a rotation. A jump that is short by more than a quarter but less than half a rotation is underrotated; a shortfall of half a rotation or more is downgraded by one full rotation.

• Underrotation (“<”): the jump falls between a quarter-rotation and a half-rotation short of the required rotation.
• Downgrade (“<<”): the jump is at least half a rotation short, so the protocol records it as one rotation lower.

The call depends on how much rotation is completed by the landing, not on whether the jump is a single, double, triple or quad. The same threshold therefore applies across jump types, even though the amount of rotation each requires differs.

What a downgrade can cost

A New York Times interactive example uses a triple Lutz to illustrate the scoring impact: it says a downgraded triple Lutz means a deduction of at least 4.1 points. That figure belongs to that specific example; it should not be treated as a current deduction for every jump, because the protocol mark and scoring consequence depend on the jump being judged.

Who makes the call, and how does replay help?

Rotation is called by the Technical Panel, not by the judges. The panel first identifies which jump was attempted, then reviews the take-off, the rotation in the air and the first instant the blade meets the ice on instant replay, and records the result on the protocol. The judges then grade execution separately.

• Jump identity comes first: a downgraded jump is still the jump the skater attempted. A downgraded triple is entered as that triple with the “<<” mark and scored at the double’s base value.
• The blade decides, not the body: shoulders and hips can keep turning after touchdown, so the panel compares the landing blade with the rotation the jump requires.
• Replay is not everywhere: at smaller competitions replay may be available to the Technical Panel only, or with fewer camera angles.

Close calls stay close. A landing near the quarter-turn or half-turn boundary can look different from two angles, and replay narrows that doubt without removing it.

How do you read a rotation call on the protocol?

Read a jump’s line on the protocol in two passes: the mark after the jump code, then the Grade of Execution (GOE).

• q: landed exactly a quarter short. The jump keeps its full base value, but the judges reduce the GOE.
• <: under-rotated, more than a quarter but less than half a turn short. The jump keeps its name, at a reduced base value listed in the ISU Scale of Values.
• <<: downgraded, half a turn or more short. The jump is valued as one with one rotation fewer.
• GOE: the judges’ execution mark on a scale from −5 to +5, applied after the panel’s call. Their guidelines also penalise an under-rotated landing, so a rotation call usually costs twice: once in base value and again in GOE.

The mark tells you the panel’s decision, not the exact points lost; that depends on the jump’s base value and the GOE. For the scoring system behind it, see how figure skating scoring works, and for the jumps themselves, figure skating jumps explained.

When a rotation call decides a result

Element scores add up to the technical elements score (TES), so one rotation call can move a skater past a rival in a close event. A rotation call is not a tie-break rule, though: when totals are level, the event’s own tie-break order applies, which we explain in how competition tiebreakers work.

The short version

• The thresholds distinguish a quarter-to-half-turn shortfall from a downgrade at half a turn or more.
• The protocol marks are “q” for a quarter short, “<” for underrotation and “<<” for downgrade.
• The Technical Panel makes the call on replay; the judges’ GOE is a separate mark.
• Take-off direction, pre-rotation and airborne rotation should not be treated as the same thing.
• A replay angle can clarify blade position but may conceal rotation toward or away from the camera.
• The New York Times triple Lutz example gives a historical deduction of at least 4.1 points; it is not a universal current jump value.
