About Dressage
Early European aristocrats displayed their horses' training in equestrian pageants, but in modern dressage competition, successful training at the various levels is demonstrated through the performance of "tests," or prescribed series of movements within a standard arena. Judges evaluate each movement on the basis of an objective standard appropriate to the level of the test and assign each movement a score from 0 to 10-zero being "not executed" and 10 being "excellent." A score of 9 (or "very good") is considered a particularly high mark.
The dressage tests performed at the Olympic Games are those of the highest level-Grand Prix. This level of test demands the most skill and concentration from both horse and rider.
Gaits and movements performed at this level include collected and extended walk, trot, and canter; trot and canter half-pass (almost a sideways movement); passage (a slow-motion trot); piaffe (a "trot in place"); one and two tempi changes (where the horse appears to skip as it changes leads in the canter); canter "zigzags"; and pirouettes (a 360-degree circle, in place, at the canter).
Tests ridden at the Olympic Games are scored by a panel of five international judges. Each movement in each test receives a numeric score and the resulting final score is then converted into a percentage, which is carried out to three decimal points. The higher the percentage, the higher the score.
Olympic team medals are won by the teams with the highest, second highest, and third highest total percentage from their best three rides in the Grand Prix test.
Once the team medals are determined, horses and riders compete for individual medals. The team competition serves as the first individual qualifier, in that the top 25 horse/rider combinations from the Grand Prix test move on to the next round. The second individual qualifier is the Grand Prix Special test, which consists of Grand Prix movements arranged in a different pattern. For those 25 riders, the scores from the Grand Prix and the Grand Prix Special are then combined and the resulting top 15 horse/rider combinations move on to the individual medal competition-the crowd-pleasing Grand Prix Freestyle.
For their freestyles, riders and horses perform specially choreographed patterns to music. At this level, the freestyle tests may contain all the Grand Prix movements, as well as double canter pirouettes, pirouettes in piaffe, and half-pass in passage. For the freestyle, judges award technical marks for the various movements, as well as artistic marks. In the case of a tie, the ride with the higher artistic marks wins.
