General terms
Rink
The skating area must be rectangular and, if possible, 60 m by 30 m, and not larger or smaller than 56 m by 26 m. ISU Events and the Olympic Winter Games need two covered, heated rinks.
Program
What a skater, pair or couple performs in a segment, to music of their choice, alone on the ice. A program must have the allowed duration plus or minus 10 seconds, or time deductions apply.
Short program
The first segment in Single and Pair Skating, 2 minutes 40 seconds, made up of seven required elements, which differ by discipline and, for juniors, by season. Elements can be performed in any order, and an element that does not meet the requirements has no value.
Free skate
The second segment, called Free Skating in Single and Pair Skating: 4 minutes for seniors and 3 1/2 for juniors. A well-balanced program is built from a limited number of jump, spin, step and choreographic elements, linked by skating movements, and any extra element is not counted.
Disciplines
Single Skating (Women and Men), Pair Skating (one woman and one man) and Ice Dance (one woman and one man). Single and Pair Skating segments are the Short Program and Free Skating; Ice Dance has Pattern Dances, a Rhythm Dance and a Free Dance.
Segment
One part of a competition. Single and Pair Skating segments are the Short Program and Free Skating; Ice Dance segments are the Rhythm Dance and Free Dance (and Pattern Dances at some competitions). The short program or rhythm dance is skated before the free skating or free dance.
Program duration
Short Program 2:40; Free Skating 4:00 for seniors and 3:30 for juniors; Rhythm Dance 2:50; Free Dance 4:00 seniors and 3:30 juniors. A skater may finish 10 seconds either side, with a 1.0 deduction for up to every 5 seconds outside; elements started after the time plus 10 seconds have no value, and a program 30 seconds or more short is not marked.
Competition and officials
Referee
The official who manages the panel of Judges, conducts the draws, times the program and interruptions, applies the deductions for time, interruptions, costume falling on the ice and similar, and decides protests and the ice condition. The Referee also judges the event.
Scoring terms
Program components score
From three Program Components: Composition, Presentation and Skating Skills. Each Judge marks each from 0.25 to 10 in steps of 0.25, the panel's trimmed mean is multiplied by a factor published by the ISU, and the factored results are added.
Base value
The starting points of an element, from the Scale of Values chart published in an ISU Communication each season. Base values rise with difficulty: for jumps with the jump type and the number of revolutions, for other elements with the Level of Difficulty.
Judges
Officials who mark the Grade of Execution of each element and the Program Components. They do not identify the elements or levels: the Technical Panel does that.
Deduction
Points subtracted from the segment score. Examples: 1.0 up to every 5 seconds for program time lacking or in excess, 2.0 per illegal element, 1.0 for costume or prop violations, 1.0 for a late start, and falls and interruptions as set in Rule 353.
Segment score
The Total Elements Score plus the Program Component Score minus any deductions. The skater with the highest total is first. Ties are broken by Total Elements Score in the short program or rhythm dance and by the Program Component Score in the free skating or free dance.
Final score
The sum of the Total Segment Scores of the two segments. A tie is broken by the higher score in the last segment skated, and then by placement in the earlier segment.
Scale of Values
The chart, published each season in an ISU Communication, of the Base Value of every element and the numeric value of each GOE from +5 to -5.
Fall
Loss of control with most of the body weight on the ice through any part other than the blades. In senior single skating the deduction is 1.0 for the first and second fall, 2.0 for the third and fourth and 3.0 for the fifth onwards; juniors lose 1.0 per fall, and pairs and couples 1.0 for a fall by one partner and 2.0 by both.
Jumps
Jump
A jump element is an individual jump, a jump combination or a jump sequence. The listed jumps are Toeloop, Salchow, Loop, Flip, Lutz and Axel, in order of difficulty, with a number of revolutions; quint jumps are not allowed.
Rotation
The number of revolutions a jump has in the air: single, double, triple or quadruple. Base values rise with the number of revolutions. Quint jumps are not allowed in any discipline.
Axel
The last of the six listed jumps in order of difficulty. The rules call it the Axel Paulsen in the short program, where a double or triple Axel is required, and an Axel type jump is required in a senior free skate. The forward take-off is not stated in the rules.
Listed jumps
The rules list six jumps in order of difficulty: Toeloop, Salchow, Loop, Flip, Lutz and Axel. They are told apart by the take-off, which the Technical Panel checks; a wrong take-off edge on a Flip or Lutz is marked with 'e' or '!'.
Combination jump
A jump combination is two or more jumps in which the landing foot of one jump is the take-off foot of the next. One full revolution on the ice between the jumps, with no weight transfer, is still a combination. In free skating one combination may have up to three jumps.
Under-rotated
A jump with more than a quarter but less than half a revolution missing, marked '<'. It scores 80 per cent of its base value and the Judges reduce the GOE. A jump with half a revolution or more missing is downgraded ('<<').
Toeloop
A toe-assisted jump taken off from a backward outside edge and landed on the same foot. The first of the six listed jumps in order of difficulty.
Salchow
An edge jump taken off from a backward inside edge of one foot and landed on the backward outside edge of the other foot. The second listed jump.
Loop
An edge jump taken off from a backward outside edge and landed on the same foot's backward outside edge. The third listed jump.
Flip
A toe-assisted jump taken off from a backward inside edge. A wrong or unclear take-off edge on a Flip or Lutz is marked 'e' or '!'. The fourth listed jump.
Lutz
A toe-assisted jump taken off from a backward outside edge, turning against the curve of the edge. The fifth listed jump, one step below the Axel.
Spins and footwork
Spin
A rotation on one foot in place. The basic positions are camel, sit and upright. A spin with fewer than three rotations is a skating movement, and the number of revolutions in each position is needed for the element to count.
Edge
The inside or outside curve of the blade used on a step or jump. In ice dance an edge is the visible tracing of one foot on one curve; a change of edge changes from one curve and edge to another.
Pairs and ice Dance-Specific terms
Lift
In Pair Skating an overhead lift is classified by the hold into five groups, determined at the moment the woman passes the top of the man's head. In Ice Dance a dance lift is a movement in which one partner is elevated, held at least 3 seconds and set down; see Dance lift.
Throw jump
A partner-assisted jump in which the woman is thrown into the air by the man at take-off and lands without assistance on a backward outside edge.
Death spiral
A pair element in which the man pivots with the knee bent and toe anchored and the woman circles around him on one edge, leaning to the ice with her head near it. The four types are backward outside, forward inside, backward inside and forward outside. It scores a Level only if both partners hold the position for at least one revolution.
Twizzle
A travelling turn on one foot with one or more rotations, quickly rotated in one continuous action. If travelling stops it becomes a solo spin. A series of checked three turns is not a twizzle, and a twizzle must have two revolutions to count in a step sequence level.
Pair skating elements
Pair Skating
The skating of two persons in unison, performing movements in such harmony as to give the impression of genuine pair skating, not independent single skating. Partners may separate from time to time, but must keep unison.
Twist lift
A lift in which the woman is thrown into the air, rotates freely and must be caught at the waist by the man before a smooth landing on one foot. The short program allows a Lutz or Flip take-off and two or three revolutions.
The ruleWhat are the rules for lifts in pair skating?Unison
Both partners moving together in harmony, in mirror skating (symmetrical) or shadow skating (parallel). It is considered in Skating Skills.
Ice dance
Ice Dance
A discipline of one woman and one man, with Pattern Dances, a Rhythm Dance and a Free Dance. At ISU Events and the Olympic Winter Games it consists of the Rhythm Dance and the Free Dance.
Pattern Dance
The skating of prescribed patterns, steps and turns to music with a defined rhythm and constant tempo, selected from a list of 35 dances, such as the Foxtrot, Tango and Waltzes. Each dance is skated by the couple alone and the number of sequences depends on the dance.
The ruleHow is ice dance different from pair skating?Free Dance
A creative dance program, 4 minutes for seniors and 3 1/2 for juniors, with required elements announced each year. The music must have a rhythmic beat and/or melody and at least one change of tempo, and the program must not have the concept of a pair or show program.
