The Skating System consists of a set of 11 rules. Each rule applies to a specific step in the process of marking and then tabulating the results. There is a systematic progression from one to the next, until you end up with the final result.
The Skating System is used for all WDSF competitions except WDSF Grand Slams and from 2017 onwards WDSF World Opens.
You can see the complete Skating System rule set in this document.
For the 2013 Grand Slam series an enhanced version (JS 2.0) was implemented.
The Judging System 2.1 which was introduced in 2015 was updated with an
improved calcuation of points.
WDSF Sports Director Marco Sietas authored this PowerPoint presentation explaininf the features of the NJS2.1. In it, he takes a look at the features that make this system a great tool to assess competitive performances in DanceSport.
The New Judging System 2.1 was used until mid-2017 for all Grand Slam tournaments and WDSF World Open competitions.
The JS 3.0 system is an improvement of the JS 2.1. It effectively reduces the problems faced with the use of JS 2.1. This system has replaced the JS 2.1 in all WDSF competitions.
The design intent for JS3 was to build on the intellectual property already invested in the JS2.1 system by considering the feedback from Adjudicators while including a mechanism that can remove "fake" scores.
Other Important Features
Features 0.25 marking scales derived from reduction. 0.25 should be awarded in consideration of a reduction rather then addition. For example if a couple consistently presents the qualities of a 9, with slight occasional mistake or deficiency, can be awarded an 8.75.
