The dressage trial consists of an exact sequence of movements ridden in an enclosed arena of 20x60m. The test is judged by one or more judges who are looking for balance, rhythm, suppleness, obedience of the horse and its harmony with the rider.

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 depending on the number of movements.
