The ISU Judging System (also called Code of Points (CoP) or the New Judging System (NJS)), is the scoring system currently used to judge the figure skating disciplines of men's and ladies' singles, pair skating, ice dancing, 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 Winter Olympic Games.
The ISU Judging System replaced the old 6.0 system in 2004. This new system was created in response to the 2002 Olympic Winter Games figure skating scandal, in an attempt to make the scoring system more objective and less vulnerable to abuse.[citation needed]

[edit] Previous judging 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 then combined to determine placements for each skater in each program. The placements for the two programs were then combined, with the free skate placement weighted more heavily than the short program. The lowest scoring individual (based on the sum of the weighted placements) was declared the winner.
[edit] Scandal and response
In 2004, after the judging controversy during the 2002 Winter Olympics, the ISU adopted the New Judging System (NJS), or Code of Points, which became mandatory at all international competitions in 2006, including the 2006 Winter Olympics.
[edit] Technical details
[edit] The technical panel
Under the new system, technical marks are awarded individually for each skating element. Competitive programs are constrained to have a set number of elements. Each element is judged first by a technical specialist who identifies the specific element. The technical specialist uses instant replay video to verify things that distinguish different elements; e.g. the exact foot position at take-off and landing of a jump. The decision of the technical specialist determines the base value of the element. A panel of twelve judges then award a mark for grade of execution (GOE) that is an integer from -3 to +3. The GOE mark is then translated into a value by using the table of values in ISU rule 322. The GOE value from the twelve judges is then averaged by randomly selecting nine judges, discarding the high and low value, and averaging the remaining seven. This average value is then added (or subtracted) from the base value to get the value for the element. Skaters can receive deductions for things like falls and for lifts that go on for too long.
[edit] Elements
The number and type of elements in a skating program depends on the event and on the level of competition. At the senior international level, single and pairs short programs contain eight technical elements. The actual eight elements are detailed for single skaters in ISU rule 310. Each skater must attempt one combination jump, two solo jumps, three spins, and two skating sequences. The eight elements required for a senior pairs short program include two lifts, two jumps, two spins, one step sequence, and one death spiral (ISU rule 313).
Senior level free programs have 14 elements for pairs and men, and 13 elements for ladies. The details of the elements are given by ISU rules 320 and 321. Pairs do 4 lifts, 4 jumps, 4 spins, and 2 step sequences. Men do 8 jumps, 4 spins, and 2 step sequences. Ladies do 7 jumps, 4 spins, and 2 step sequences.
[edit] Protocol details
Following an event, the complete judges scores are published in a document referred to as a protocol. There are specific notations used on the protocols.
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 judges may have marked it. On ISU protocol sheets, elements that have been nullified by this are denoted by an asterisk(*) next to the element name. If a jump has been called as having an incorrect take-off edge (for example, an inside edge on a lutz jump take-off), that jump is marked with an e, for incorrect edge.
Jumps done in combination 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 can be downgraded to a "sequence", in which case the base value is 0.8 times the sum of the individual jumps. The jumps normally executed at the senior level, and their base values, are quad toe loop (9), triple Axel (7.5), triple Lutz (6), triple flip (5.5), triple loop (5), triple Salchow (4.5), triple toe loop (4) and double Axel (3.5).

[edit] Program Components
The former presentation mark has been replaced by five categories, called program components. The components are (1) skating skills (SS), (2) transitions (TR), (3) performance/execution (PE), (4) choreography (CH), and (5) interpretation (IN). A detailed description of each component is given in ISU rule 322.2. Each component is awarded a raw mark from 0 to 10 in increments of 0.25, with a mark of 5 being defined as "average". The five raw marks are then translated into a program mark by multiplying by a factor that depends on the program and the level.
For senior ladies and pairs, the factor is 0.8 for the short program and 1.6 for the long program. For senior men, the factor is 1 for the short program and 2 for the long program. The factors are set so that the total score from the artistic marks will be about equal to the total score from technical marks. Senior men tend to have higher element scores than ladies because they have more jumping passes and attempt higher valued jumps, so their program components are factored higher to reflect the difference.
[edit] In ice dancing
Ice dancing 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 5 marked technical elements. In the free dance, there are 9 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 exact values of these factors are listed in ISU Rule 543.1k.

[edit] Subjectivity
Judging in figure skating is inherently subjective. Although there may be general consensus that one skater "looks better" than another, it is difficult to get agreement on what it is that 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 get more experience with the new system, there may emerge more consensuses. However, for the 2006 Olympics there were cases of 1 to 1.5 points differences in component marks from different judges.[citation needed] This range of difference implies that "observer bias" determines about 20% of the mark given by a judge.[citation needed] 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]
[edit] Criticism
The ISU judging system moves figure skating closer to judging systems used in sports like diving and gymnastics. It also has some features intended to make judging more resistant to pressure by special interests. However, there is debate whether the new system is an improvement over the old 6.0 system.[citation needed]
Under the ISU rules, the judges' marks are anonymous, which removes any public accountability of the judges for their marks. The random panel selection procedure can change a skater's mark by several points and alter the outcome of competitions depending on which subset of judges are chosen. The United States Figure Skating Association has split with the ISU on these two issues. In the U.S., the judges names remain associated with the marks. Also the U.S. uses only nine judges and counts all nine of their scores.
[edit] Ties
While COP has minimized the number of ties and the need for multiple tiebreaks like there was under 6.0, ties still do occur. At the 2007 World Figure Skating Championships, Yukari Nakano and Carolina Kostner tied for 5th place with 168.92 points overall. Nakano won 5th place on the tiebreak, which was the free skate placement, and Kostner dropped to 6th.[4] Ties for single segments of the competition also occur. At the 2004 Skate America, Alissa Czisny and Cynthia Phenuef tied in the short program at 50.20, with both earning a TES score of 25.40 and a PCS score of 24.80.[5]
