{{Short description|Ice skating scoring system}}
{{Use dmy dates|date=May 2018}}

The '''ISU Judging System''' or the '''International Judging System''' (IJS), occasionally referred to as the '''Code of Points''' (COP) system,<ref>{{cite web|url=https://www.swisstiming.com/sports/figure-skating/|title=Swiss Timing and Figure Skating|work=2017 Swiss Timing|access-date=25 March 2018}}</ref> is the scoring system that has been used since 2004 to judge the [[figure skating]] disciplines of [[single skating|men's and ladies' singles]], [[pair skating]], [[ice dancing|ice dance]], and [[synchronized skating]]. It was designed and implemented by the [[International Skating Union]] (ISU), the ruling body of the sport. 

This system of scoring is used in all international competitions sanctioned by the ISU, including the [[Olympic Games]]. The ISU Judging System replaced the previous [[6.0 system]]. It was created partially in response to the [[2002 Winter Olympics figure skating scandal]], in an attempt to make the scoring system more objective and less vulnerable to abuse.<ref>{{cite news|title=Scoring System Approved|work=[[The New York Times]]|date=10 June 2004 |url=https://www.nytimes.com/2004/06/10/sports/sports-briefing.html?ref=internationalskatingunion|access-date=25 July 2011}}</ref> U.S. Figure Skating has released a summary of the new judging system.<ref name="Anon. h495">{{cite web | title= UNDERSTANDING THE INTERNATIONAL JUDGING SYSTEM| url=https://usfigureskating.org/sites/default/files/media-files/Scoring%20Cheat%20Sheet.pdf | access-date=2023-09-18}}</ref>
==Previous judging system==
{{main|6.0 system}}
Figure skating was formerly judged on a 6.0 scale. This scale is sometimes called "the old scale", or "old system". Skaters were judged on "technical merit" (in the free skate), "required elements" (in the short program), and "presentation" (in both programs). The marks for each program ran from 0.0 to 6.0 and were used to determine a preference ranking, or "ordinal", separately for each judge; the judges' preferences were combined to determine placements for each skater in each program. The placements for the two programs were then combined, with the free skate weighted more heavily than the short program.
<!-- "Lowest scoring" is correct in the following sentence; 1.0 factored placements beat 2.0 factored placements, and 1.0 is lower than 2.0. -->The highest scoring individual (based on the sum of the weighted placements) was declared the winner.

==Scandal and response==
{{main|2002 Winter Olympics figure skating scandal}}
A judging controversy occurred during a pair skating event at the [[2002 Winter Olympics]], which used scoring based on the [[6.0 system]]. A second award ceremony was held in which the top two teams were both awarded gold medals. In 2004, the ISU adopted the New Judging System (NJS), or Code of Points, in an effort to establish a more objective system. This became mandatory at all international competitions in 2006, including the [[2006 Winter Olympics]]. The ISU released an explanation of the advantages of the new system over the 6.0 system.<ref name="Anon. o645">{{cite web | title= Frequently Asked Questions (FAQ) on the ISU New Judging System | url=https://www.isu.org/isu-statutes-constitution-regulations-technical-rules-2/isu-judging-system/275-new-judging-system-faq/file | access-date=2023-09-18}}</ref>

==Technical details==

===Technical panel===
Under the ISU Judging System, the base value of each element performed by the skater is identified by the Technical Panel. The purpose of this panel is to identify all of the elements performed by the skater in real time as they happen.  The panel is also responsible for identifying any "technical errors" to jumps; identifying falls of the skater; and the "levels of difficulty" performed in Spins and Steps.

The Technical Panel is composed of the following three people:<ref name="ISU Media Guide 23-24">{{cite web | title=ISU Figure Skating Media Guide 2023/24 | url=https://www.isu.org/media-centre/guides/media/32039-figure-skating-media-guide-2023-24/file | access-date=2023-10-12}}</ref>
# The Technical Controller (TC), who supervises the panel, and breaks ties on technical decisions during the "review of elements" when the TS and ATS do not agree. The TC is also responsible for "rule vetting" the program. The TC can discard any elements from scoring that break the rules for that level and specific program.
# The Technical Specialist (TS), who verbally calls the elements as they happen.
# The Assistant Technical Specialist (ATS), who takes written notes on all of the elements performed and to contribute to any decisions on technical calls during the "review of elements".

The Technical Panel is assisted by two people:
# The Data Operator (DO) assists the Technical Panel for recording purposes, and is supervised by the TC. The DO inputs the codes of the elements and levels of difficulty into the computer system.
# The Replay Operator (RO) operates an instantaneous slow-motion video replay system and supports the Technical Panel in the identification of the performed elements.<ref name="ISU Media Guide 23-24"/><ref name="US Rulebook 22-23">{{cite web | title= THE 2023-24 OFFICIAL U.S. FIGURE SKATING RULEBOOK| url=https://www.usfigureskating.org/sites/default/files/media-files/2023-24%20Rulebook.pdf | access-date=2023-09-19}}</ref>

===Judging panel===

The role of the judges is to evaluate the quality of each element performed (Technical Score) and the quality of the performance (Presentation Score).  At most international events and other large National Championships (such as the U.S. Championships), there are nine judges.<ref name="ISU Media Guide 23-24"/> At smaller competitions the panel might consist of between four and seven judges. An odd number of judges was needed to break ties in the old 6.0 system, but this is no longer necessary with averaging marks in the ISU Judging System.

==== Technical Element Score (TES) ====
Each element performed has a base value (which depends on its difficulty), and the judges assign a Grade of Execution (GOE), which can increase or decrease the base value. The GOE is marked as an integer from -5 to +5 since the [[2018–19 figure skating season|2018–19 season]]. Before the system change, the scale went from -3 to +3. Each plus or minus step in the GOE results in increasing or decreasing the base value by 10 % in single and pair Skating and by 16 % in ice dance. The total of all element scores gives the final Technical Element Score (TES).<ref name="ISU Media Guide 23-24"/>

==== Program Component Score (PCS) ====
In addition to the Technical Element Score, the judges award points on a scale from 0.25 to 10.00 with increments of 0.25 for different program components to grade the overall presentation of the performance. Since the [[2022–23 figure skating season|2022–23 season]], the judging panel evaluates three components: Composition (CO), Presentation (PR) and Skating skills (SK). Before the system change, the judges evaluated five components: Skating skills (SS), Transitions (TR), Performance (PE), Composition (CO) and Interpretation (IN). The total of all components is called the Program Component Score (PCS).

* ''Composition'' (CO): This evaluates how the program is designed in relation to the music; how are the different elements connected; how is the available space used; how does the choreography reflect musical phrase and form? 
* ''Presentation'' (PR): This evaluates how the program is performed; what does the skater express and project; what energy is created; what is the musical sensitivity and timing; for Pair, Ice Dance and Synchronized skating is the skating appropriately synchronized and showing awareness of space?
* ''Skating skills'' (SK): This mark assesses the skater's command of the blade over the ice, including the ability to skate with power and ease. The judges look at variety and clarity of edges, balance, body control, turns, steps, flow, power and speed.<ref name="ISU Media Guide 23-24"/><ref name="US Rulebook 22-23"/>

==== Computation of scores ====
The judging panel consists of up to nine judges and one referee. The Technical Panel sends the element codes to the judges' computers for marking. For each element, all of the judges award a mark for Grade of Execution (GOE) that is an integer between –5 and +5. The GOE mark is then translated into a value using the Scale of Value (SOV) table which is published regularly by ISU Communications.<ref name="isu_rules">{{cite web |title=ISU Constitution & Regulations |url=https://www.isu.org/inside-isu/rules-regulations/isu-statutes-constitution-regulations-technical |access-date=2022-04-22 |website=Isu.org}}</ref> The GOE values from the nine judges are averaged using the "[[trimmed mean]]" procedure, where the highest and lowest values are discarded and an average is calculated from the remaining seven values.<ref name="isu_rules" /> This average value (which may be positive or negative) is finally added to the base value to produce the judging panel's overall score for the element.

Judges also mark the Program Components, which are: Skating Skills; Presentation; and Composition. These Components are marked on a scale of 0.25–10 with 0.25 increments and averaged using the same "trimmed mean" procedure that was used for averaging the GOE marks. Judges also have the power to input majority deductions such as Music Violations and Costume/Prop Violations. The Referee inputs other deductions such as Time Violations, Interruption in Excess and Costume Failures.

===Technical elements===
The number and type of technical elements included in a skating program depend on the event and on the level of competition. At the senior international level, the [[Short program (figure skating)|short program]] for senior singles skaters must contain seven technical elements: (a) double or triple axel, (b) triple or quad [[Figure skating jumps|jump]], (c) jump combination including triple or quad jumps (maximum one double jump), (d) flying [[Figure skating spins|spin]], (e) [[camel spin|camel]] or [[sit spin|sit]] spin with only one change of foot, (f) [[Figure_skating_spins#Other_spins|spin combination]] with only one change of foot, and (g) [[step sequence]].<ref name="TechRules 2022">{{cite web | title=Special Regulations & Technical Rules Single & Pair Skating & Ice Dance 2022 |last1=ISW|date=14 September 2022| url=https://www.isu.org/inside-isu/rules-regulations/isu-statutes-constitution-regulations-technical/special-regulations-and-technical-rules/29500-single-pair-and-ice-dance-2022/file | access-date=2023-09-28}}</ref>{{rp|Rule 611}} The [[Free skating|free program]] for senior singles skaters must contain (a) a maximum of seven jumps, one of which must be an Axel, (b) a maximum of three spins (one a combination, one flying and one with a single position), (c) a maximum of one step sequence, and (d) maximum of one choreographic sequence.<ref name="TechRules 2022"/>{{rp|Rule 612}}

The short program for senior pairs skaters for the season 2023-24 shall consist of the following required elements: (a) any hip lift take-off (hand to hip or upper part of the leg position), (b) double or triple twist lift, (c) double or triple throw jump, (d) double or triple solo jump, (e) solo spin combination with only one change of foot, (f) death spiral forward inside, and (g) step sequence.<ref name="TechRules 2022"/>{{rp|Rule 620}} The free skating program for senior pairs skaters must contain: (a) maximum of three lifts, not all from the same group, (b) maximum of one twist lift, (c) maximum of two different throw jumps, (d) maximum of one solo jump, (e) maximum of one jump combination or sequence, (f) maximum of one pair spin combination, (g) maximum of one death spiral different from the death spiral of the Short Program, (h) maximum of one choreographic sequence.<ref name="TechRules 2022"/>{{rp|Rule 621}}

===Component factoring===
The panel's points for each Program Component are multiplied by a factor depending on the event. For singles and pair skating, the factor is uniform for all components, as follows:<ref name="TechRules 2022"/>{{rp|Rule 353(m)}}

The factors in ice dance are different for each Program Component and depend on the dance type.<ref name="TechRules 2022"/>{{rp|Rule 353(m)}}

===Protocol details===
Following an event, the complete judges' scores are published in a document referred to as a ''protocol''. This document uses specific notations as described below.

If a skater attempts more than the allowed number of a certain type of element in a program, then the element is still described and called as such by the technical controller, but receives a base value of 0 as well as a GOE of 0, regardless of how the judges have marked it. On ISU protocol sheets, elements that have been nullified by this are denoted by an asterisk (*) next to the element name. In free skating, for jumps executed twice as solo jumps, the second jump is marked as +REP and receives 70% of its base value. Jump elements performed after the halfway point of a program are marked with x and receive a 10% bonus added to their base value. If a jump has been called as having an unclear take-off edge, that jump is marked with ! and receives a –1 to –2 GOE depending on severity; if a jump has been called as having an incorrect take-off edge (for example, an inside edge on the take-off of a [[Lutz jump]]), that jump is marked with e and receives a –2 or –3 GOE depending on the severity of the edge fault. Jumps that are under-rotated are marked with < or << depending on the degree of turns completed on the ice instead of in mid-air. < indicates that a jump had less than a ½ turn but more than a ¼ turn completed on the ice, reducing the base value to 70% of its original value. << indicates a severe under-rotation (a ½ turn or more) and the jump is valued as if it had one less rotation (e.g. a triple would receive the value of a double).<ref name=isu1611>{{cite web |url=http://isu.sportcentric.net/db//files/serve.php?id=1862 |title=Communication No. 1611 – Single & Pair Skating – Scale of Values, Levels of Difficulty and Guidelines for marking Grade of Execution |date=4 May 2010 |publisher=[[International Skating Union]] |format=PDF |archive-url=https://web.archive.org/web/20100513221826/http://isu.sportcentric.net/db/files/serve.php?id=1862 |archive-date=13 May 2010 |url-status=dead |access-date=9 January 2015}}</ref>

Jumps that are executed in combination or sequence are marked as a single element, with a base mark equal to the sum of the base marks for the individual jumps. However, a combination or sequence can be downgraded – marked with +COMBO (combinations in the short program) or +SEQ (combinations and sequences in the free skate) – in which case the sum of the base values of the jumps is reduced to 80% of its original value.

====Scale of Values (SOV) and abbreviations of common elements====
Every spring/summer the ISU releases rule updates which include a current Scale of Values (SOV) for different types of element. One is released for Singles/Pairs<ref name="SOV SP 2023">{{cite web | title=Communication 2475—Scale of Values Single and Pair Skating 2022/23 | url=https://www.isu.org/inside-isu/isu-communications/communications/28337-isu-communication-2475/file | date=4 May 2022|access-date=2023-09-28}}<br/>Per Communication 2558, ISU Communication 2475 Scale of Value Single & Pair Skating will remain valid for season 2023/24.</ref><ref name="LOD 2024">{{cite web | title= Communication 2558—Levels of Difficulty and Guidelines for marking Grade of Execution and Program Components Season 2023/24|date=9 August 2023 | url=https://www.isu.org/figure-skating/rules/fsk-communications/31153-isu-communication-2558/file | access-date=2023-09-28}}</ref> and another for Ice Dance.<ref name="SOV ID 2024">{{cite web | title=Communication No. 2564—Ice Dance Scale of Values season 2023/24 | url=https://www.isu.org/figure-skating/rules/fsk-communications/31294-isu-communication-2564/file | access-date=2023-09-28|date=31 May 2023}}</ref> Click "show" below to view the abbreviations and codes for different figure skating elements.

The level of a spin or footwork sequence is denoted by the number following the element abbreviation. The number of rotations on a jump is denoted by the number preceding the element abbreviation. For example, 3A denotes a triple Axel, while SlSt4 denotes a level four straight line step sequence. ChSt and ChSq are step sequences and spiral sequences that have no level and a fixed base value.

===In ice dance===
[[Ice dancing|Ice dance]] judging is similar to pairs and singles, but uses a separate set of rules and table of values. In the compulsory dance, steps are specified and "elements" are defined for each dance as subsets of the prescribed steps. For compulsory dance only, there is no program component score given for transitions and choreography. Instead there is a timing (TI) program component that is exclusive to the compulsory dance, leaving only four program components in the compulsory dance. In the original dance there are five marked technical elements. In the free dance, there are nine marked technical elements. Unlike singles and pair skating, the different program components are weighted differently in each segment of the competition. The highest factored component(s) in each segment are skating skills and timing in the compulsory dance, interpretation in the original dance, and transitions in the free dance. The calculation of these factors is described in Rule 353.<ref name="Special Tech 2022">{{cite web | title= ISU SPECIAL REGULATIONS & TECHNICAL RULES SINGLE & PAIR SKATING and ICE DANCE 2022 | url=https://www.isu.org/inside-isu/rules-regulations/isu-statutes-constitution-regulations-technical/special-regulations-and-technical-rules/29500-single-pair-and-ice-dance-2022/file | access-date=2023-09-28}}</ref>

== Highest scores ==

After being trialed in 2003, the IJS replaced the old [[6.0 system]] in the 2004–2005 figure skating season. Up to and including the [[2017–2018 figure skating season|2017–2018 season]], the Grade of Execution (GOE) scoring system for each program element ranged between –3 and +3. Starting with the 2018–2019 season, the GOE was expanded to range between –5 and +5. Hence, the [[International Skating Union]] (ISU) have restarted all records from the 2018–2019 season and all previous statistics have been marked as "historical".<ref>{{cite web |url=http://www.isu.org/statistics |title=Statistics including Personal Best & Season's Best information |publisher=[[International Skating Union]] |access-date=22 July 2016}}</ref>

The ISU only recognizes the best scores that are set at international competitions run under the ISU's rules, and does not recognize, for example, scores that are obtained at national figure skating championships. The competitions recognized by the ISU are: [[Figure skating at the Olympic Games|Winter Olympics]] (including the team event), [[Figure skating at the Youth Olympic Games|Youth Olympics]] (including the team event), [[World Figure Skating Championships|World Championships]], [[World Junior Figure Skating Championships|World Junior Championships]], [[European Figure Skating Championships|European Championships]], [[Four Continents Figure Skating Championships|Four Continents Championships]], [[ISU Grand Prix of Figure Skating|GP events]], [[ISU Junior Grand Prix|Junior GP events]], [[ISU Challenger Series|Challenger Series events]], and [[ISU World Team Trophy in Figure Skating|World Team Trophy]].

==Subjectivity==
Like [[gymnastics]] and [[Diving (sport)|diving]] competitions, judging in figure skating is intrinsically [[Subjectivity|subjective]]. Although there may be general consensus that one skater "looks better" than another, it is difficult to reach agreement on what causes one skater to be marked as 5.5 and another to be 5.75 for a particular program component. As judges, coaches, and skaters gain more experience with the new system, greater consensus may emerge. However, for the 2006 Olympics there were cases of 1 to 1.5 point differences in component marks from different judges.{{Citation needed|date=March 2008}} This range of difference implies that "observer bias" determines about 20% of the mark given by a judge.{{Citation needed|date=February 2008}} Averaging over many judges reduces the effect of this bias in the final score, but there will remain about a 2% spread in the average artistic marks from the randomly selected subsets of judges.{{Citation needed|date=March 2008}}

Aside from intra-expert subjectivity, skating is very open to misjudgement from everyday spectators who only see skating casually, e.g. every four years at the Olympics. A skater's jump may look perfect, but the general public will not be aware that the competitor landed on an incorrect edge, therefore receiving fewer points for an element, resulting in the appearance of haphazard or biased judging.

==Criticism==
The aim of the IJS is to ensure that the judging of figure skating competitions is more consistent with the judging of sports such as [[Diving (sport)|diving]] and [[gymnastics]]. It also includes features intended to make judging more resistant to pressure by special interests. However, there is debate as to whether the new system is in fact an improvement over the old 6.0 system.<ref>{{cite news|url=https://www.theguardian.com/sport/2006/feb/19/winterolympics2006.winterolympics1 |title=Jury is out on skating's latest judging system |first=Clare |last=Balding |date=19 February 2006 |work=[[The Guardian]] |access-date=2 October 2019}}</ref><ref name=":0">{{cite news |last1=Pilon |first1=Mary |last2=Longman |first2=Jere |date=5 February 2014 |title=Despite Revamp, Figure Skating Gets Mixed Marks |work=[[The New York Times]] |url=https://www.nytimes.com/2014/02/06/sports/olympics/despite-revamped-system-for-judging-figure-skating-gets-mixed-marks.html |access-date=2 October 2019 |archive-url=https://web.archive.org/web/20140206083202/https://www.nytimes.com/2014/02/06/sports/olympics/despite-revamped-system-for-judging-figure-skating-gets-mixed-marks.html |archive-date=6 February 2014}}</ref> One criticism of the adoption of the IJS was in the way it alienated casual figure skating fans; whereas the 6.0 system was universally understood due to its simplicity and intuitive scale, the large cumulative scores given by the IJS are less intuitive.<ref name=":0" /> Judging bias was also found to be about 20 percent greater in the IJS than in the 6.0 system, with judges being inclined to give higher marks to skaters from their own country.<ref name=":0" /> 

Initially under the new ISU rules, the judges' marks were anonymous, which removed any public accountability of the judges for their marks. However, problems with this system came to the forefront during the [[2014 Winter Olympics|Sochi Olympics in 2014]] following Russian skater [[Adelina Sotnikova]]'s victory over [[Yuna Kim]]. In large part due to the judging and technical panels including four Russians, these results sparked a debate over the judges' objectivity.<ref>{{Cite web |date=2017-08-27 |title=Olympic figure skater won't defend gold medal |url=https://www.espn.com/olympics/story/_/id/20477424/adelina-sotnikova-defend-olympic-figure-skating-gold-medal-pyeongchang |access-date=2022-08-18 |website=ESPN.com |language=en}}</ref> In June 2016 the ISU Congress voted to abolish anonymous judging altogether.<ref>{{cite web|url=https://www.insidethegames.biz/articles/1038244/isu-vote-to-abolish-anonymous-judging-system-in-figure-skating-to-increase-transparency|title=ISU vote to abolish anonymous judging system in figure skating to "increase transparency"|work=inside the games|date=8 June 2016|access-date=25 March 2018}}</ref>

==Ties==
While the IJS has minimized the number of ties and the need for multiple tiebreaks, as there were under the old 6.0 system, ties do still occur for both overall score and also for single segments of the competition. Short/rhythm segment ties are broken based on the TES score and free segment ties on the PCS. For ties in the overall score, ties are broken based on the free segment placement.

==Judge reduction in 2008==
In 2008, the [[International Skating Union|ISU]] ruled to reduce the number of judges from twelve to nine. The need to reduce costs was given as the prime reason for this change.<ref>{{cite web|url=http://web.icenetwork.com/news/article.jsp?ymd=20090428&content_id=64320&vkey=ice_news|title=How many judges are there, anyway?|first=Lynn|last=Rutherford|website=web.icenetwork.com|date=28 April 2008|access-date=25 May 2018}}</ref> Since the highest and lowest extreme scores are discounted, the scores of seven judges (rather than ten) determine the outcome of competitions.
