How Dressage is scored

Each movement in the test is scored on a scale from 0 to 10, with a score of "10" being the highest possible mark and with the total maximum score for the test varying depending on the level of competition and the number of movements. Therefore, if one movement is poorly executed, it is still possible for the rider to get a good overall score if the remaining movements are very well executed. The marks are added together and any errors of course deducted. To convert this score to penalty points, the average marks of all judges are converted to a percentage of the maximum possible score, subtracted from 100 and the multiplied by a co-efficient decided by the governing body. EG. 77 percent becomes 34.5 penalty points or (100 - 77) x 1.5 = 34.5

Once the bell rings the rider is allowed 45 seconds to enter the ring or is eliminated.
If all four feet of the horse exit the arena during the test, this results in elimination.
If the horse resists more than 20 seconds during the test, this results in elimination.
Errors on course:
1st: minus 2 marks
2nd: minus 4 marks
3rd: elimination

An obstacle is defined as having been knocked down if any part of its height is lowered. It is therefore possible to knock out a pole below the top pole and receive no penalties, as long as the highest pole stays in place, so that the jump retains the same height. It does count as a knockdown if the highest pole falls out of one jump cup but remains in the other; although part of the pole remains at the original height, the other part is lowered.

The winner is the horse and rider with the fewest penalties. Awards are usually presented while mounted, before the placed riders take a lap of honor around the arena.
