lower levels. For example, some riders who consider themselves to be training classically would not ask their horse to hold his head near-vertical when he first began training, and this would be penalized at the lower levels of competitive dressage, marked down because the horse is not considered to be correctly on the bit. Other riders, who also would consider themselves classically trained, would disagree, saying that if a horse is not ready to travel in a correct outline (on the bit) he is not ready for competition, and this is the reason such horses would be marked down. The highest form of classical riding, as well as dressage, high school dressage, or haute école, takes years for both the horse and rider to master. When a horse is advanced in its training, it can perform not only Grand Prix dressage movements such as collected and extended gaits, passage and piaffe, but some can also perform certain "Airs Above the Ground," although usually a horse will only be trained in one air, and only if it is particularly able. The school jumps The "high school" or haute ecole school jumps, popularly known as the "airs above the ground", include the courbette, capriole, levade, and ballotade. Though these movements are said to come from when the horse was used in war, in their modern form, the airs were unlikely to have been used in actual battle, as all but the capriole expose the horse's sensitive underbelly to the weapons of foot soldiers, and they were more likely training exercises used off the battlefield. The courbette is a movement where the horse balances on its hind legs and jumps, keeping its fore legs off the ground, thus it "hops" on its hind legs. The capriole is a movement where the horse leaps into the air and pulls his fore legs in towards his chest at the height of elevation, while kicking out with his hind legs. The levade' is a movement where the horse is balanced on its haunches at a 45° angle from the ground. It requires great control and balance, and is very strenuous. Two main breeds are most well known for their abilities for airs above ground: the Lipizzaner and the Andalusian. Other breeds known for their abilities in high school dressage include the Friesian and Lusitano. The Spanish Riding School in Vienna, as well as the Cadre Noir
